The molecular masses of α-glucosidase A and B were 78 kDa and 82 kDa by SDS-PAGE, and 62 kDa and 70 kDa by gel filtration, respectively. α-Glucosidase A had high activity not only toward maltooligosaccharides but also toward α-glucans. The optimum pH was 4.5-5.5 and about 50% of the activity remained after incubation at 65℃ for 20 min. On the other hand, α-glucosidase B had high activity toward maltooligosaccharides but faint activity toward α-glucans. The optimum pH was 5.0 and no activity was found after incubation at 65℃ for 20 min. The enzymatic and immunological properties of α-glucosidase A and B were similar to those of α-glucosidase. Tor U, and α-glucosidase V or W, isolated from spinach seeds without 4℃ storage, respectively. These findings suggest that the α-glucosidase in spinach seeds is modified to be two molecular forms. en-copyright= kn-copyright= en-aut-name=FuruiSatoshi en-aut-sei=Furui en-aut-mei=Satoshi kn-aut-name=古井聡 kn-aut-sei=古井 kn-aut-mei=聡 aut-affil-num=1 ORCID= en-aut-name=SugimotoManabu en-aut-sei=Sugimoto en-aut-mei=Manabu kn-aut-name=杉本学 kn-aut-sei=杉本 kn-aut-mei=学 aut-affil-num=2 ORCID= en-aut-name=SuzukiYukio en-aut-sei=Suzuki en-aut-mei=Yukio kn-aut-name=鈴木幸雄 kn-aut-sei=鈴木 kn-aut-mei=幸雄 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Spinach kn-keyword=Spinach en-keyword=α-Glucosidase kn-keyword=α-Glucosidase en-keyword=Multiple molecular forms kn-keyword=Multiple molecular forms END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=135 end-page=144 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=1998 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=イネ幼植物から調整した細胞壁に含まれるペクチン質の性状 kn-title=Characteristics of Pectic Polysaccharides from Rice Shoots en-subtitle= kn-subtitle= en-abstract=イネ幼植物から調整した細胞壁から、50mMの1,2−シクロヘキサンジアミン四酢酸と炭酸ナトリウムにて、ペクチン質を化学的に抽出した。抽出される全ペクチン質に含まれる糖含量は、乾燥細胞壁重の約1％に相当した。両者の薬剤で抽出されたペクチン質をDEAE−Trisacryl Mカラムトグラフィーによって、5種の多糖画分に分画し、主要3画分の構成糖組成と分子量を検討した。1,2−シクロヘキサンジアミン四酢酸で抽出され上記カラムに未吸着の中性多糖画分は、アラビノース、ガラクトースから成り、分子量56kDaであった。また、炭酸ナトリウムで抽出されカラムに未吸着の中性多糖画分は、アラビノース、キシロース、ガラクトースから成り、分子量30kDaであった。一方、酸性多糖画分は、中性糖側鎖を持った、ラムノガラクツロナンとホモガラクツロナンを含んでいた。Erwinia carotovora Er.からのエンド−ペクチン酸リアーゼとKluyveromyces fragilisからのエンド−ポリガラクツロナーゼの精製標品を、イネ細胞壁に作用させたところ、0.4〜0.6％に相当するペクチン質断片が可溶化された。一方、上述したカラムトグラフィーで得られた82kDaのラムノガラクツロナンにエンド−ポリガラクツロナーゼを作用させると、多量のガラクツロン酸が遊離され、また、未分画分は90％以上のガラクトースとアラビノースから成っていた。この結果から、この酸性多糖画分の”hairly”領域は、エンド−ポリガラクツロナーゼの作用できないガラクトースとアラビノースのみから成る側鎖であった。 kn-abstract=Pectic polysacchasides from the starch-free cell wall preparation of rice (Oryza sativa) shoots have been extracted in sequence with cyclohexane-trans-1,2-diaminetetra-acetate(CDTA)and Na2CO3. The total amount of polysaccharides extracted with the agents was estimated as approximately 1% of the cell walls. The extracted polysaccharides were fractionated by DEAE-Trisacryl M ion-exchange chromatography yielding five fractions, and the monosaccharide composition and molecular mass were constructed from homogalacturonan and rhamnogalacturoanan containing the "hairy" region with galactosyl and arabinosyl side-chains. The solubilized pectic polysaccharides after treatment with two pectolytic enzymes accounted for 0.4〜0.6% of the starch-free cell walls. en-copyright= kn-copyright= en-aut-name=KonnoHaruyoshi en-aut-sei=Konno en-aut-mei=Haruyoshi kn-aut-name=今野晴義 kn-aut-sei=今野 kn-aut-mei=晴義 aut-affil-num=1 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=2 ORCID= en-aut-name=YamasakiYoshiki en-aut-sei=Yamasaki en-aut-mei=Yoshiki kn-aut-name=山崎良樹 kn-aut-sei=山崎 kn-aut-mei=良樹 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Cell wall kn-keyword=Cell wall en-keyword=Oryza sativa kn-keyword=Oryza sativa en-keyword=Pectic polymer kn-keyword=Pectic polymer END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=2 article-no= start-page=201 end-page=213 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Ixia から分離された bean yellow mosaic virus kn-title=Characterization of Bean Yellow Mosaic Virus from Ixia hybrida en-subtitle= kn-subtitle= en-abstract=1992年に岡山県倉敷市玉島で、葉に斑入りを生じた球根類花卉植物Ixia hybridaからpotyvirus(Ixia-B)が分離され、その諸性質から　bean yellow masaic virus(BYMV)と同定された。本ウイルスを11科47種の植物に接種したとこと、フリージャ、Nicotiana clevelandii、Chenopodium amaranticolar、ソラマメ、クリムソンクローバー、インゲンマメ、ホウレンソウに全身感染し、またC.quinoa、フダンソウ、ツルナ、センニチコウなどに局部感染したが、エンドウ、ササゲ、ダイズなどには感染しなかった。本ウイルスをはモモアカアブラムシにより非永続的伝搬され、C.quinoa の病葉粗汁液中での安定性は耐熱性が55℃〜60℃（10分）、耐希釈性10-3〜10-4、耐保存性2〜4日であった。DN法試料の電顕観察で多くのpotyvirusよりやや長い約820nmのひも状粒子と管状封入体の破片が見られた。感染葉の超薄切片では風車状、層板状の封入体、dence body、細胞質に散在するウイルス粒子が観察された。本ウイルスはfreesia mosaic virusおよびclover yellow vein virusの抗血清と反応せず、また本ウイルス抗血清を用いた寒天ゲル内二重拡散法ではBYMV分離株（Cro-4, BYMV-G）と反応したが、本ウイルスとBYMVのCro-4およびBYMV-G間にspurが形成され、異種抗原の存在が認められた。外被タンパク質の分子量は約34Kで、ssRNAのサイズは約9Kbであった。Papain,chymotrypsin,pepsinを用いた外被タンパク質のぺプタイドマッピングでは、本ウイルス、Cro-4、BYMV-G、Cal-35の部分分解パターンがそれぞれ異なり、外被タンパク質がアミノ酸配列レベルで異なっていることが示唆された。 kn-abstract=A strain (Ixia-B) of bean yellow mosaic virus (BYMV) isolated from Ixia hybrida was characterized and compared with other isolates of BYMV and clover yellow vein virus (CYVV). Ixia-B was transmitted by aphids,Myzus presicae in a non-presistent manner and by sap-inoculation to 11 of 46 species in 5 of 10 families tested, and had a similar host range to that of some BYMV isolates, althrough some defferences were detected. Sap from diseased C. quinoa was infective after 10 min heating at 55℃ but not 60℃, after a dilution to 10-3 but not 10-4, and after 2 days but not 4 days at 20℃.The Virus particles were filamentous rods of about 13×820 nm. Ixia-B contaied a single protein species with a molecular weight of 34,000 and a single viral RNA with approximately 9,000 bases. In ultrahtin sections of leaf tissues from infected plants, the virus particles, cylindrical cytoplasmic inclusions and dense bodies were obsserved in the cytoplasm. The antiserum to Ixia-B produced by immunizing a rabbit had a titer of 1/512. A close serological relationship was revealed between Ixia-B and two strains of BYMV from crocus and gladiolus, but no relationship to clover yellow vein virus was found in agar gel diffusion tests. However,Ixia-B could be distinguished from two strains of BYMV by the formation of spurs among them in agar gel and by the differences in the patterns of peptide mapping of coat proteins. From these findings, Ixia-B was identified as a strain of BYMV. en-copyright= kn-copyright= en-aut-name=TsujiToshiya en-aut-sei=Tsuji en-aut-mei=Toshiya kn-aut-name=辻俊也 kn-aut-sei=辻 kn-aut-mei=俊也 aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name=近藤秀樹 kn-aut-sei=近藤 kn-aut-mei=秀樹 aut-affil-num=3 ORCID= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Ixia hybrida kn-keyword=Ixia hybrida en-keyword=Bean yellow mosaic virus kn-keyword=Bean yellow mosaic virus en-keyword=Potyvirus kn-keyword=Potyvirus END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=1-2 article-no= start-page=58 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The cladosporium leaf mold of chestnut caused by Cladosporium epiphillum (Pers.)

Test plants were Oryza sativa (Rice), Hordeum vulgare (Barley), Lactuca sativa (Lettuce), Cucumis sativus (Cucumber), Daucus carota (Carrot), Brassica pekinesis (Chinese cabbage), Spinacia oleracea (Spinach) and Raphanus sativus (Radish). From the absorption characteristics of NH4+ and NO3- between a single salt solution of NH4NO3 and a complete nutrient solution containing NH4NO3, the test plants were classified into goup 1(rice,barley and lettuce), which absorbed NH4+ more rapidly than NO3- in both absorption solutions, group 2(cucumber and carrot), which absorbed NH4+ slightly more than NO3- in the single salt solution of NH4NO3, the tendency of which was reversed in the complete nutrient solution containing NH4NO3, and goup 3(Chinese cabbage,spinach and radish), which absorbed NO3- clealy more than NH4+ in the complete nutrient solution, whereas the absorption of NH4+ or NO3- was almost equal in the single salt solution of NH4+NO3-. The above classisication of plants could be explained by the balance of a repressive or competitive characteristics of NH4+ absorption mainly as sociated with a capacity for absorption of calcium ion(Ca2+) and magnesium ion(Mg2+), and the relative root affinity to NO3- that can be evaluated by the relative absorption of NO3- to mono-phosphate ion(H2PO4-) in plant roots. The group 1 plants are the so-called acid tolerant plants, which appeared to be tolerant to NH4+, and showed a marked pH decreased during the 24 hours of the absorption experiments in those plants.

To elucidate the interaction between the midget chromosome and rye cytoplasm, in this study, an attempt was made to isolate rye-type cDNAs from a cDNA library of (cereale)-CS by differential screening. Two replica filters from each plate were hybridized with digoxigenin (DIG)-labeled wheat CS cDNAs and with DIG-labeled rye cDNAs,respectively. Out of ca. 20,000 plaques, 27 were hybridized more strongly with rye cDNAs than with CS cDNAs. These clones were classified into six classes (T-Y) by blot hybridization. The majority of the clones (21 out of 27) was belonged to the same class (1), showing rye-type RFLP (restriction fragment length polymorphism). The DNA sequence of clone CrClA in class T, was very similar to that of wheat ribulose 1,5-bisphosphate carboxylase,large subnit gene, rbcL(94.5% homology). However, the 3' end of CrClA was shorter than that of wheat rbcL, and terminated at TAA instead of TAG, like the rbcL of Aegilops crassa. In the clone CrC5.4, the first half of the sequence was similar to that of one rice EST clone, the functions of which are not known, and the latter was similar to the reverse sequence of maize 4.5S-23S ribosomal RNA. This suggests that CrC5.4 had been derived from two defferent cDNAs of (cereale)-CS. Three other clones had homology to the chlorophyll a/b binding protein genes (cab) of wheat, maize and tomato, and one to wheat rbcS (ribulose1,5-bisphosphate carboxylase small subnit gene). However, no clear polymorphisms were detected between wheat and rye by using those clones as probes. en-copyright= kn-copyright= en-aut-name=MurataMinoru en-aut-sei=Murata en-aut-mei=Minoru kn-aut-name=村田稔 kn-aut-sei=村田 kn-aut-mei=稔 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=Cytoplasm substitution line kn-keyword=Cytoplasm substitution line en-keyword=Differential screening kn-keyword=Differential screening en-keyword=Midget chromosome kn-keyword=Midget chromosome en-keyword=Rye kn-keyword=Rye en-keyword=Wheat kn-keyword=Wheat END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=2 article-no= start-page=53 end-page=65 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=197503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characteristics and inheritance of EMS-induced mutants in barley I.

In Cd-polluted areas, the fields are affected by both wastewater and the emissions from the chimneys of zinc refineries or plating factories. The application of inhibition agents, such as slaked lime, calcium silicate or fused magnesium are applied to inhibit the absorption of these metals by plants. Many reports have been made on the decrease of metal absorption through the application of some form of calcium, phosphate or silicate. Also, it has been reported that wheat is more sensitive to CdS than to CdO. However, almost all experiments were performed at less than 500 ppm Cd in soil, and these experiments have not been made at a concentration close to the level critical for wheat plants. There have been few reports on the effects of calcium cabonate on metal tolerance or metal uptake at the a level critical wheat. The typical example of using calcium carbonate was investigated by Maeda, and the application of phosphate by Koshino, and by Muramoto et al. The effects of calcium carbonate on the metal content of wheat to the critical levels were examined. en-copyright= kn-copyright= en-aut-name=MuramotoShigeki en-aut-sei=Muramoto en-aut-mei=Shigeki kn-aut-name=村本茂樹 kn-aut-sei=村本 kn-aut-mei=茂樹 aut-affil-num=1 ORCID= en-aut-name=NishizakiHisao en-aut-sei=Nishizaki en-aut-mei=Hisao kn-aut-name=西崎日佐夫 kn-aut-sei=西崎 kn-aut-mei=日佐夫 aut-affil-num=2 ORCID= en-aut-name=AoyamaIsao en-aut-sei=Aoyama en-aut-mei=Isao kn-aut-name=青山勲 kn-aut-sei=青山 kn-aut-mei=勲 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=181 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=タバコ懸濁培養細胞におけるアルミニウムの二価鉄、銅およびカドミウム毒性に対する影響 kn-title=Effects of Aluminum on the Toxicity of Iron(II), Copper and Cadmium in Suspension-cultured Tobacco Cells en-subtitle= kn-subtitle= en-abstract=二価鉄[Fe(U)]、銅（Cu)およびカドミウム（Cd）の細胞毒性に対するアルミニウム（Al）の効果について検討した。120μM AlCl3の存在もしくは非存在下において、対数増殖期の細胞をFeSO4,CuSO4,CdCl2で各々18時間、pH4.0で処理した。処理後の生存率は、処理後の細胞を増殖させたのちに、未処理細胞（コントロール）の増殖に対する金属で処理した細胞の相対増殖率で求めた。Al,Fe(U),Cdの単独処理による増殖阻害は、各々300μM、200μM、500μMの濃度まで観察されなかったが、Cuでは15μMで大きく阻害された。このように、タバコ細胞は相対的にAl、Fe（U）、Cdには感受性が低く、Cuには感受性が高かった。細胞をFe（U）およびAlの両方で処理すると、増殖は著しく阻害され、AlおよびFeの細胞内含量も相乗的に増加した。Cuで処理した場合、Alを加えることにより逆に増殖率が増加した。しかし、細胞内Cu含量はAlの影響を受けなかった。Cd処理の場合、Alを加えてもCdによる増殖阻害の程度は変わらなかった。このように、AlはFe（U）、Cu、Cd毒性に対して各々異なる相互作用を示し、Fe（U）に対し、相乗効果を、Cuに対しては拮抗的な阻害を示したが、Cdに対してはみかけ上効果がなかった。 kn-abstract=The effects of aluminum (Al) on the cytotoxicity of ferrous iron (Fe(U)), copper(Cu) and cadmium(Cd) were studied. Log-phase cells were treated with either FeSO4,CuSO4, or CdCl2 in the presence or absence of AlCl3(120μM) for 18h at pH 4.0. After the treatment, the viability was determined as relative growth of the metal-treated cells to the untreated control cells during the post-treated culture. A single treated with either Al, Fe(U) or Cd did not inhibit the growth at the metal concerntrations up to 300 μM, 200 μM and 500 μM, respectively, whereas the growth was markedly inhibited at 15 μM Cu. Thus,the cells were relatively insensitive to Al, Fe(U) and Cd and sensitive to Cu. When cells were treated with both Fe(U)(120 μM)and Al(120μM), the growth was significantly inhibited and the cellular contents of both Al and Fe increased synergistically. After the treatment with Cu(0 to 10 μM) with or without Al, the cells grew more vigorously when they were treated in the presence of Al, althrouh the Cu content of the cells were not alterd by Al. The presence of Al during the treatmemt with Cd(0 to 2 μM) had no effect on the degree of growth inhibition by Cd. Thus, Al interacts with the toxicity of Fe(U), Cu and Cd in different manners; synergistic with Fe(U), antagonistic with Cu and apparently no effeco on Cd. en-copyright= kn-copyright= en-aut-name=YamamotoYoko en-aut-sei=Yamamoto en-aut-mei=Yoko kn-aut-name=山本洋子 kn-aut-sei=山本 kn-aut-mei=洋子 aut-affil-num=1 ORCID= en-aut-name=ChangYi-Chieh en-aut-sei=Chang en-aut-mei=Yi-Chieh kn-aut-name=張藝潔 kn-aut-sei=張 kn-aut-mei=藝潔 aut-affil-num=2 ORCID= en-aut-name=OnoKanji en-aut-sei=Ono en-aut-mei=Kanji kn-aut-name=小野寛治 kn-aut-sei=小野 kn-aut-mei=寛治 aut-affil-num=3 ORCID= en-aut-name=MatsumotoHideaki en-aut-sei=Matsumoto en-aut-mei=Hideaki kn-aut-name=松本英明 kn-aut-sei=松本 kn-aut-mei=英明 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Aluminum kn-keyword=Aluminum en-keyword=Antagonistic kn-keyword=Antagonistic en-keyword=Nicotiana tabacum kn-keyword=Nicotiana tabacum en-keyword=Suspension culture kn-keyword=Suspension culture en-keyword=Synergistic kn-keyword=Synergistic END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=1-2 article-no= start-page=67 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=1965 dt-pub=196512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Sexual compatibility between form species of Erysiphe graminis DC. and viability of the ascospores derived from the inter-form-specific hybridization. kn-title=Erysiphe graminis DC.のform species間の和合性およびform species間交雑により形成された子のう胞子の寄生力 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HiuraU. en-aut-sei=Hiura en-aut-mei=U. kn-aut-name=日浦運治 kn-aut-sei=日浦 kn-aut-mei=運治 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=4 article-no= start-page=239 end-page=247 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=197703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Genetics of host-parasite interaction in formae speciales of Erysiphe graminis kn-title=Erysiphe graminisのformae specialesとそれらの宿主との相互関係の遺伝 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HiuraU. en-aut-sei=Hiura en-aut-mei=U. kn-aut-name=日浦運治 kn-aut-sei=日浦 kn-aut-mei=運治 aut-affil-num=1 ORCID= en-aut-name=HetaH. en-aut-sei=Heta en-aut-mei=H. kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=39 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=1997 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ラン科植物に発生するシンビジウムモザイクウイルスの血清学的検出 kn-title=Evaluation of Dot-Immunobinding Assay and Rapid Immunofilter Paper Assay for　Detection of Cymbidium Mosaic Virus in Orchids en-subtitle= kn-subtitle= en-abstract=Dot-immunobinding assay （DIA）法とrapid immunofilter paper assay （RIPA）法の2種の血清学的診療法をcymbidium mosaic virus （CyMV）の検出に適用したところ、両方法とも少なくとも純化ウイルスで100ng/ml、罹病葉汁液では10-4希釈まで検出可能であった。DIA法では検出に5〜6時間要したが、本法は多量の資料の診断に適していると思われた。一方、RIPA法では本ウイルスをDIA法と同程度の検出感度で数分以内で正確に検出できたことから、本法は今後のCyMVの簡易・迅速診断法として多種属のラン科植物に広く活用できると考えられた。さらにRIPA法ではCyMVとORSVに重複感染した植物から両ウイルスを同時に検出できた。 kn-abstract=Dot-immunobinding assay (DIA) on nitrocellulose membranes and rapid immunofilter paper assay (RIPA) were examind for their usefulness in the detection of cymbidium mosaic virus (CyMV) in orchids. The minimum detection levels of CyMV by these methods were 100 ng/ml in purified preparations and at 10-4 dilution of extracts from infected leaves of orchids could be detected by these methods. Although DIA took 5 to 6 hours for the detection of the virus, it was reliable method for diagnosis of a large-number of samples. On the other hand, RIPA, which enabled detection of CyMV within a few minutes with sensitivity similar to that of DIA, will be suitable as a rapid and handy tool for virus disease diagnosis in orchids. Moreover, by RIPA, we could detect CyMV and odontoglossum ringspot virus (ORSV) simultaneously form doubly infected plant. en-copyright= kn-copyright= en-aut-name=I WayanGara en-aut-sei=I Wayan en-aut-mei=Gara kn-aut-name=イ　ワヤンガラ kn-aut-sei=イ　ワヤン kn-aut-mei=ガラ aut-affil-num=1 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name=近藤秀樹 kn-aut-sei=近藤 kn-aut-mei=秀樹 aut-affil-num=2 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Serological detection kn-keyword=Serological detection en-keyword=Cymbidium mosaic virus kn-keyword=Cymbidium mosaic virus en-keyword=Orchid kn-keyword=Orchid END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=2 article-no= start-page=91 end-page=103 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ニンジン懸濁培養細胞の培養液に分泌される細胞外多糖成分 kn-title=Extracellular Polysaccharides from the Culture Medium of Cell Suspension Cultures of Carrot en-subtitle= kn-subtitle= en-abstract=植物培養細胞は懸濁（液体）培養を行うことによって、細胞壁構成多糖成分と構造的に類似している多糖成分を、その培地中に分泌することが知られており、これまで数種の植物培養細胞について報告されている。そこで、これまで研究例のないニンジン培養細胞を使用して、その細胞外多糖成分について検討した。ニンジン懸濁培養細胞の対数増殖後期の培養濾液からエタノール分画によって多糖成分を集め、DEAE-Sepharose CL-6およびDEAE-Trisacry Mカラムクロマトグラフィーによって、数種の多糖画分に分画し、それら画分の構成糖組成を検討した。また、上記カラムに吸着しない中性多糖分画は、分子量52kDaと40kDaの2種の画分から成り、Trichoderma virideから分子量52kDaの画分はキシログルカンであると示唆された。一方、上記カラムに吸着する酸性多糖画分は、DEAE-Trisacryl M カラムクロマトグラフィーによって数種の画分に分画された。その中で、分子量80kDaを示す主要画分は、Erwinia carotovora Er.から精製したエンド‐ペクチン酸リアーゼ、Kluyveromyces fragilisから精製したエンド‐ポリガラクチュロナーゼ、ニンジン培養細胞から精製したα-L-アラビノフラノシダーゼやβ-ガラクトシダーゼなどによって分解されなかった。しかし、50mMのトリフルオロ酢酸による分解にて、4％に相当するガラクトースを含む生成物が遊離された。これらの結果から、この酸性多糖画分は、複雑な中性糖側鎖の結合したラムノガラクチュロナン領域（”Hairy”region）であることが示唆された。 kn-abstract=The extracellular polysaccharides have been fractionated from the culture medium of carrot(Daucus carota)cell culrures by precipitation with ethanol and by chromatography on DEAE-Sepharose CL-6B DEAE-Trisacryl M ion-exchange and Bio-Gel A-1.5m gel-permeation.The sugar composition and molecular mass of purified neutral and acidic polymers were determined.

Plants responded by developing chemicals and morphological defense to arthropods. Some secondary metabolic substances in plants have been assumed to be toxic or deter feeding. Aconitic acid in the barnyard-grass subspecies, Echinochloa oryzycola Vasing has been reported to be an active component against brown rice planthopper Nilapalvata lugens (Stal) (Kim et al. 1976). Aphids, Ropalosiphum padi. L., R. maidis (F.), Schizaphis graminum (Rondani)and Sitobion akeviae (Shinji), are important pests of barley (Hordeum vulgare L.) and wheat (Triticum aesstivum L.). On barley plants, more than seven aphids per stem causes yield loss (Hansen 1990). R. maidis sometimes severely infested corn plants (Zea mays L.), the leaves being wet by honeydew. Melanaphis sacchari (Zehntner) caused brownish decay of leaves of a susceptible line・ of sorghum Sorghum bicolor Moench. We examined the relation between aconitic acid contents and aphid densities in wheat, barley, corn, sorghum, barnyard grass and rice (Rustamani et al. 1992a). The plants containing larger amounts of aconitic acid showed a moderate degree of resistance to aphids. The findings obtained on additional lines in 1991, and on other components, such as DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), are reported herein. en-copyright= kn-copyright= en-aut-name=A.RustamaniMaqsood en-aut-sei=A.Rustamani en-aut-mei=Maqsood kn-aut-name=ルスタマニマクスード kn-aut-sei=ルスタマニ kn-aut-mei=マクスード aut-affil-num=1 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=2 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=3 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=79 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=オオムギの組換え型自殖系統、同質遺伝子系統、および倍加半数体系統を用いた発芽時における耐塩性の遺伝解析 kn-title=Genetical Studies on Salt Tolerance at Germination in Recombinant Inbred, Isogenic,　and Doubled Haploid Lines of Barley (Hordeum vulgare L.) en-subtitle= kn-subtitle= en-abstract=オオムギの発芽時みおける耐塩性と形態マーカーとの連鎖関係を調べるために、Russia 6×HES 4の交雑から養成した組換え型自殖系統125系統と同質遺伝子系統70系統、およびLeger×CI 9831の交雑から養成した倍加半数体145系統の種子を1.5％の塩化ナトリウム溶液を用いて20℃、12時間日長の条件で発芽させ、置床後10日後に調査してシュートを25mm以上抽出した種子の置床種子に対する割合をもって発芽時の耐塩性とした。各種主働遺伝子が発芽時の耐塩性に及ぼす影響を解析するために、組換え型自殖系統、同質遺伝子系統、および倍加半数体系統を親品種間の間で異なる形質によって群別し、発芽時の耐塩性を比較した。その結果、Russia 6×HES 4の組換え型自殖系統、および同質遺伝子系統においては六条型は二条型よりも耐塩性が有意に強く、また、Leger×CI 9831の倍加半数体系統においては二条型は六条型よりも、底刺の短毛は長毛よりもそれぞれ耐塩性が有意に強く、条性間の耐塩性の強弱は交雑組合せによって逆転した。一方、芒の粗滑、穂密度、および頴色の比較においては有意差が認められなかった。以上の結果から、条性を支配するν遺伝子、および底刺のタイプを支配するs遺伝子と発芽時の耐塩性を支配する遺伝子との関連性が推察された。また、芒の粗滑を支配するr遺伝子、穂密度を支配するl遺伝子、および頴色を支配するRe-2遺伝子と発芽時の耐塩性は独立であると考えられた。 kn-abstract=To determine the relationship between morphological markers and salt tolerance at germination in barley (Hordeum vulgare L.), a total of 125 recombinant inbred (RI) lines of Russia 6×HES 4, a seriesof 70 isogenic (IG) lines for V/ν gene derived from Russia 6×HES 4, and 145 doubled haploid (DH) lines of Leger×CI 9831 were evaluated for their salt tolerance at germination.

This sequence is 6611 nucleotides long containing four open reading frames, which correspond to 126 K,183 K,31 K and 18 K proteins. The 5' non-coding region of ORSV Cy-1 is 62 nucleotides. The ORFs encoded a 126 K polypeptide and a 183 K read-through product in which helicase-sequence and polymerase-sequence motifs are found. The5' non-coding region,which extends from bases 1 to 62 has 2G residues and the ribosome binding site (AUU). The3' non-coding region of ORSV Cy-1 composes 414 nucleotides in length. The genomic organization of ORSV Cy-1 is nearly identical to that of ORSV Korean strain(ORSV-K).

Infection scores varied among the cultures and barley varieties, and their interactions were observed. Principal component analysis of the infection scores revealed that the cultures could be classified into three groups by first and second components (contributing 40.2% and 15.6% of the total variance, respectively), and that two Japanese cultures could be distinguished from the others isolated in Europe and North America. This indicates that the fungus is geographically differentiated in the reaction of the barley varieties to the cultures. Furthermore, East Asian barley varieties differed from European ones in their reactions to the culltures, while barley varieties from regions between East Asia and Europe showed a large genetic diversity in their reactions. en-copyright= kn-copyright= en-aut-name=KonishiTakeo en-aut-sei=Konishi en-aut-mei=Takeo kn-aut-name=小西猛郎 kn-aut-sei=小西 kn-aut-mei=猛郎 aut-affil-num=1 ORCID= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Powdery mildew kn-keyword=Powdery mildew en-keyword=Geographic distribution kn-keyword=Geographic distribution en-keyword=Differentiation kn-keyword=Differentiation END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=73 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=オオムギのアブラムシ抵抗性とグラミン：EDTA法による解析 kn-title=Gramine and Resistance of Barley to Aphids : Analysis of EDTA Exdates from Barley Leaves en-subtitle= kn-subtitle= en-abstract=オオムギのアブラムシ抵抗性要因物質の一つ、グラミンは幼苗に多量に存在している。アブラムシ口針切断法とEDTA法を用いて、アブラムシが吸汁するオオムギの師管液にグラミンが存在しているかどうか検討した。幼苗に寄生しているアブラムシの口針をレーザ光線を用いて切断したが、師管液は得られなかった。オオムギ葉を切断しEDTA溶液に浸し、切り口から液中に浸潤してくる成分は師管液に非常に類似したものといわれている。このEDTA法により得られた浸潤液のグラミンと糖の含量を時間を追って測定したところ、グラミンが師管液中に存在する可能性を示唆する結果を得た。 kn-abstract=Young leaves of barley contain a large amount of gramine, which is one of the factors involved in the resistance of barley against aphids.

The time course of sucrose and gramine content of EDTA exudates from barley leaves suggested the existence of gramine in phloem sap. en-copyright= kn-copyright= en-aut-name=YoshidaHideya en-aut-sei=Yoshida en-aut-mei=Hideya kn-aut-name=吉田英哉 kn-aut-sei=吉田 kn-aut-mei=英哉 aut-affil-num=1 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=2 ORCID= en-aut-name=KawadaKazuo en-aut-sei=Kawada en-aut-mei=Kazuo kn-aut-name=河田和雄 kn-aut-sei=河田 kn-aut-mei=和雄 aut-affil-num=3 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Resistance to aphids kn-keyword=Resistance to aphids en-keyword=Gramine kn-keyword=Gramine en-keyword=EDTA kn-keyword=EDTA en-keyword=Localization kn-keyword=Localization END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=4 article-no= start-page=269 end-page=277 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Detection of Leek Yellow Stripe Virus by Dot-immunobinding Assay kn-title=Leek yellow stripe virusのdot-immunobinding assayによる検出ならびにその診断への利用 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NodaChiyoichi en-aut-sei=Noda en-aut-mei=Chiyoichi kn-aut-name=野田千代一 kn-aut-sei=野田 kn-aut-mei=千代一 aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=2 ORCID= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=2 article-no= start-page=145 end-page=149 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cloning of PCR-Products Encoding Potassium Channel Proteins from Mesembryanthemum crystallinum kn-title=Mesembryanthemum crystallinum(ice plant)におけるカリウムチャンネルをコードするPCR産物のクローニング en-subtitle= kn-subtitle= en-abstract=耐塩性、耐乾性の極めて高い Mesembryanthemum crystallinum からPCR法を用いてカリウムチャンネル遺伝子断片を得た。2つのクローンが独立に得られたが、互いによく似ていて、シロイヌナズナのカリウムチャンネルとは67から88％の相同性を示した。サザンハイブリダイゼーションの結果から、今回得られた遺伝子はシングルコピーであり、またカリウムチャンネル遺伝子ファミリーが存在する可能性が示唆された。 kn-abstract=Gene fragments of potassium channels were cloned from Mesembryanthemum crystallinum by using RT-PCR (reverse transcription-polymerase chain reaction).

The sizes of each cDNA clone for RNAs 1,2,3,4 and 5 molecules were 3.0, 1.7, 1.8, 1.5 and 1.4 kbp, respectively. cDNA inserts to RNA 2 were covered at a part of the 3'regions, and those of RNAs 3,4 and 5 were almost full-length. The plasmids containing each of cDNA inserts were labeled with digoxigenin by the random priming method. Northern blot hybridization tests showed that individual probes hybridized specially to each of the five RNAs. Good results were obtained with 1 to 10 ng of RNA as a mixture of five RANs, but the probe to RNA 3, RNA 4 or RNA 5 gave a weak signal with hererologous RNAs when more than 10 ng RNA was used. In dot blot hybridization, the limit of detection was about 10 pg RNA, but if a higher content of RNA was spotted, cross reaction occurred using heterologous RNAs. For laboratory and field isolates of BNYVV, each of RNAs 3,4 and 5 was easily detected by Northern blot hybridization in total nucleic acids extracted from Tetragonia expansa leaves inoculated mechanically, but not from roots of sugar-beet plants inoculated by the fungus Polymyxa betae. However, satisfactory results were obtained with partially purified or concentrated preparations from roots. These findings indicate that the digoxigenin-labeled probes are useful for the identification and detection of RNAs contained in field and laboratory isolates of BNYVV. en-copyright= kn-copyright= en-aut-name=SaitoMinako en-aut-sei=Saito en-aut-mei=Minako kn-aut-name=齊藤美奈子 kn-aut-sei=齊藤 kn-aut-mei=美奈子 aut-affil-num=1 ORCID= en-aut-name=KiguchiTadahiko en-aut-sei=Kiguchi en-aut-mei=Tadahiko kn-aut-name=木口忠彦 kn-aut-sei=木口 kn-aut-mei=忠彦 aut-affil-num=2 ORCID= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name=玉田哲男 kn-aut-sei=玉田 kn-aut-mei=哲男 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Sugar beet kn-keyword=Sugar beet en-keyword=Rhizomania kn-keyword=Rhizomania en-keyword=BNYVV kn-keyword=BNYVV en-keyword=RNA detection kn-keyword=RNA detection en-keyword=Nonradioactive cDNA probe kn-keyword=Nonradioactive cDNA probe END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=123 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=カクヤリグサ科一年生雑草における数量分類学的研究 kn-title=Numerical Taxonomic Study in Annual Cyperaceous Weeds en-subtitle= kn-subtitle= en-abstract=カヤツリグサ科の3種の雑草カヤツリグサ（C.microiria Steud.）12系統、コゴメガヤツリ（Cyperus iria L.）12系統およびチャガヤツリ（C.amuricus Maxim.）6系統を岡山県、鳥取県および東京都なら採集して倉敷で栽培し、形態的特性、バイオマスおよび種子生産性など21形質を調査した。各形質を分散分析したところ系統間差はいずれも有意であったが、種間の値は多くの形質で重複し、単一形質による種の判別は困難であった。21形質間の相関行列を主成分分析したところ、上位3主成分の累積寄与率は83％と大きく、第1主成分（37％）は小穂の形態と種子生産性、第2主成分（28％）は生長量、第3主成分（18％）は種子重と小穂密度とそれぞれ関係が深いとみられた。第1主成分と第3主成分によって供試30系統は3群に分けられ、各群はそれぞれの種と一致した。さらに、第2主成分と第3主成分によってカヤツリグサ種内の系統は主として生長量の異なる3群に分類できた。クラスター分析によって供試30系統は4つの大きな群に分けられた。一番目の群には、C.amuricusの全系統、二番目の群にはC.microiriaの3系統、三番目の群にはC.microiriaの残りの系統、および最後のクラスターにはC.iriaの全系統が含まれた。従って、C.microiriaha形態的および生態的形質において異なる2ないし3の生態型から成ると考えられた。このように数量分類学あるいは多変量解析はカヤツリグサ科の雑草の種間ならびに種内の分類に極めて有効な解析法であることが示された。 kn-abstract=Three species of Cyperaceous weeds, Cyperus iria (12 strains), C.　microiria(12 strains) and C. amuricus (6 strains), were collected from different sites of Okayama, Tottori and Tokyo prefectures, and various morphological characters, biomass and seed production were observed on the plants which were cultivated at Kurashiki. The analysis of variance showed a significant difference among the strains in each character. However, the species overlapped with each other in most morphological characters. Prinipal component analysis on the 21 characters showed that 83% of the total variation could be explained by the first three components: the first component (37%) was regarded as factors concerning spikelet and seed production; the second component (28%) was regarded as factors concerned the size of vegetative parts; the third component (18%) was largely affected by seed weight and floret density. Scatter diagram on the first and third principal components showed that the 30 strains of three species divided into three groups, and strains in each group correspond to the three species without exception. Based on the second and third principal components, strains of C. microiria were further divided into three sub-groups according to size of vegetative parts. Using the cluster analysis, 30 strains of these species were divided into four large clusters; the first was composed of C. amuricus strains, the second was of three strains of C. microiria, the third included the remaining strains of C. microiria, and the last cluster was composed of C. iria strains. It may be concluded that C. microiria is composed of two or three ecotypes which are different in morphological and reproductive traits. en-copyright= kn-copyright= en-aut-name=Muhamad AhmadChozin en-aut-sei=Muhamad Ahmad en-aut-mei=Chozin kn-aut-name=Muhamad AhmadChozin kn-aut-sei=Muhamad Ahmad kn-aut-mei=Chozin aut-affil-num=1 ORCID= en-aut-name=SatouKazuhiro en-aut-sei=Satou en-aut-mei=Kazuhiro kn-aut-name=佐藤和広 kn-aut-sei=佐藤 kn-aut-mei=和広 aut-affil-num=2 ORCID= en-aut-name=YasudaShozo en-aut-sei=Yasuda en-aut-mei=Shozo kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Cyperus iria kn-keyword=Cyperus iria en-keyword=Cyperus microiria kn-keyword=Cyperus microiria en-keyword=Cyperus amuricus kn-keyword=Cyperus amuricus en-keyword=Numerical taxonomy kn-keyword=Numerical taxonomy en-keyword=Speciation kn-keyword=Speciation END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=2 article-no= start-page=147 end-page=158 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=日本とカナダの春播オオムギから採取した大麦網斑病菌株の病原性の変異 kn-title=Pathogenic Variation of Pyrenophora teres Isolates Collected from Japanese and Canadian Spring Barley en-subtitle= kn-subtitle= en-abstract=北海道およびカナダの春播オオムギがら採取した22の大麦網斑病菌株（Pyrenophora teres Drechs.）を世界各地のオオムギ38品種に幼苗接種し、病斑指数によって病原性の変異を検討した。分散分析の結果、菌株の病原力ならびに品種の抵抗性には有意差が認められたが、菌株と品種の交互作用は統計的には有意でなかった。各菌株の反応をFinlay-Wilkinson（1963）の回帰分析によって解析したところ、北海道とカナダの菌株で病原性反応に差が認められた。この傾向はカナダの菌株のうち、通常のNet typeの菌株よりも斑点状病斑を示すSpot typeの菌株で顕著であった（Fig.1）。さらに、菌株と品種の交互作用を詳細に解析するために相互作用と相乗交互作用モデル（AMMIモデル）を適用して交互作用に関する主成分分析を行った結果、各菌株は日本のNet type、カナダのNet type、カナダのSpot typeの3群に分けられた（Fig.1）。各菌株について群間ならびに群内の相関係数を算出したところ（Table5）、Net typeの菌株相互の相関係数は0.601〜0.969と相対的に高かったが、一部の菌株と品種の組合わせでは抵抗性反応の逆転がみられた（Fig.4）。一方、Spot typeの菌株とNet typeの菌株の相関係数は0.302〜0.538と低く、両者の病原性は多少異なることが示された。このような一部の菌株と品種の間に認められる弱い交互作用は、抵抗性を支配する主働遺伝子の特異的な反応が、いわゆる圃場抵抗性を支配する微働遺伝子の作用によって修飾された結果と考えられる。 kn-abstract=Twenty-two isolates of Pyrenophora teres Drechs. collected from Japanese and Canadian spring barleys were inoculated to 38 barley varieties having various genetic backgrounds. The analysis of variance for the discase ratings showed that there were significant differences both in the virulence of isolates and the resistance of varieties. However, the interaction among isolates and varieties was not statistically significant. Both Finlay-Wilkinson regression analysis and principal component analysis by Additive Main effects and Multiplicative Interaction effects(AMMI)model classified the isolates into three groups,which were different in origins and sympton types.

However, the population of Rhopalosiphum padi sometimes differed with the seedling. The plant resistance to the natural infestation of cereal aphids was obvious at the heading stage. There was a negative correlation between the high population density of aphids and gramine concentration.

In every F2 and F3 population, disease ratings showed a continuous distribution. As many F3 lines with intermediate resistance had a smaller variance and homozygous genotype, the resistance might be controlled by a few genes. The heritabilities of the disease rating were estimated　by correlation coefficients and regression coefficients between each F2 plant and the descended F3 lines. Another estimate for heritability was calculated by the selection differential in the F2 plants and genetic gain in the F3 lines. Despite the different level of resistance in the resistant parents of the two crosses, the three kinds of heritabilities estimated were similar and ranged from 0.6 to 0.8. Because of the fewer number of genes controlling the disease resistance and the higher heritabilities, selection in a early generation may be effective for net blotch resistance in barlcy. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name=佐藤和広 kn-aut-sei=佐藤 kn-aut-mei=和広 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Net blotch kn-keyword=Net blotch en-keyword=Pyrenophora teres kn-keyword=Pyrenophora teres en-keyword=Selection kn-keyword=Selection en-keyword=Barley kn-keyword=Barley en-keyword=Disease resistance kn-keyword=Disease resistance END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=2 article-no= start-page=113 end-page=129 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=高対塩性オオムギ品種の選抜 kn-title=Selection for High Salt Tolerant Cultivars in Barley en-subtitle= kn-subtitle= en-abstract=耐塩性品種を選抜するため、500品種のオオムギを用い、水耕栽培実験を行った。培地の塩化ナトリウム濃度は2（対照区）、150および300mMとした。用いた品種500品種は、4581品種のオオムギから、発芽時の耐塩性の高い品種として選抜されたものである。1回に約100品種を用い、5回の水耕栽培実験で耐塩性の高い105品種を選抜した。この105品種を同一時期に水耕栽培し、主として塩化ナトリウム300mMでの地上部収量を比較することにより、最終選抜を行った。その結果、10余品種の高対塩性オオムギが得られた。これらの高対塩性オオムギ品種では、塩化ナトリウム150mMの場合に、対照区の42〜86％、300mMの場合に対照区の17〜30％の地上部収量が得られた。これらの実験に用いたオオムギ品種から、対塩性の高いもの、中程度のもの、および低いものを各々10数品種選び、それらのイオン含量を測定した。その結果、同一グループ内でもイオン含量にかなりの変動が見られるが、対塩性の高いグループでは、オオムギのナトリウム吸収に比較し、カリウム吸収の大きい傾向を認めた。 kn-abstract=In order to select higher salt tolerant cultivars of barley,solution culture experiments were carried out with 500 barley cultivars, which were preliminarily selected from 4581 cultivars by exposure to 1-2% of sodium chloride(MaCl) during the germinating stage.

Then the final selection was carried out on those 105 cultivars, and it was found that more than 10 cultivars were highly salt tolerant, mainly based on the comparisons of shoot yields under the supply of 300 mM of NaCl.High salt tolerant barley cultivars mentioned above showed 42-86% and 17-30% of the control in shoot yield under the condition of 150 and 300 mM of NaCl, respectively.On three groups of barley,each having more than 10 cultivars, which are high, moderate and low in salt tolerance, ion contents of the plants were analyzed.The results suggest that potassium(K) uptake was comparatively larger in the high salt tolerant goup of barley cultivars,through there was a big variation in sodium(Na) and K contents even within the same group. en-copyright= kn-copyright= en-aut-name=SopandieDidy en-aut-sei=Sopandie en-aut-mei=Didy kn-aut-name=SopandieDidy kn-aut-sei=Sopandie kn-aut-mei=Didy aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= en-aut-name=MoritsuguMasumi en-aut-sei=Moritsugu en-aut-mei=Masumi kn-aut-name=森次益三 kn-aut-sei=森次 kn-aut-mei=益三 aut-affil-num=3 ORCID= en-aut-name=KawasakiToshio en-aut-sei=Kawasaki en-aut-mei=Toshio kn-aut-name=川ｱ利夫 kn-aut-sei=川ｱ kn-aut-mei=利夫 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Ion content kn-keyword=Ion content en-keyword=Salt tolerance kn-keyword=Salt tolerance en-keyword=Sodium chloride kn-keyword=Sodium chloride en-keyword=Yield kn-keyword=Yield END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=43 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=1999 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=エビネから分離されたインゲンマメ黄斑モザイクウイルスの諸性質 kn-title=Some Properties of Bean Yellow Mosaic Virus Isolated from Calanthe sp.(Orchidaceae) in Japan en-subtitle= kn-subtitle= en-abstract=山口県で採集した葉にモザイク症状を示すエビネからインゲンマメ黄斑モザイクウイルス（BYMV）が分離された。本ウイルスは汁液接種により試験した12科46種のうち9科29種に感染し、モモアカアブラムシにより非永続的に伝搬された。本ウイルスの粗汁液中での安定性、粒子の形態、管状封入体及び細胞内結晶状封入体の形態は既報のBYMVのそれらと同様であった。SDS-PAGEによる外被タンパク質の分子量は35,000であった。微沈降反応及びDAS-ELISAにおいて、本ウイルスはクロッカス及びグラジョラスから分離されたBYMVと血清学的に近縁であったが、グラジョラス分離株よりもクロッカス分離株の方が本ウイルスとより近縁であった。 kn-abstract=Bean yellow mosaic virus (BYMV) was isolated from Calanthe sp.showing mild chlorosis on the leaves, collected in Yamaguchi Prefecture in Japan. The virus was transmitted by the aphid Myzus persicae in a non-persistent manner, and by sap-inoculation to 29 out of 46 plant species from 9 out of 12 families tested. Stability in crude sap, morphology of virus particles, shape of cylidrical inclusions and the presence of cytoplasmic crystalline inclusions in the infected cells were similar to those of BYMV isolates previously reported. The virus contained a single protein species with a molecular weight of 35,000. In a microprecipition test and double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), the virus showed a close serological relationship to isolates of BYMV from both crocus and gladiolus, and showed a distant relationship to clover yellow vein virus. Three BYMV isolates used in this study were found to be serologically related to each other, but the virus was more closely related to the BYMV crocus isolate than to gladiolus isolate. en-copyright= kn-copyright= en-aut-name=MatsumotoJun-Ichi en-aut-sei=Matsumoto en-aut-mei=Jun-Ichi kn-aut-name=松本純一 kn-aut-sei=松本 kn-aut-mei=純一 aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=2 ORCID= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Calanthe sp. kn-keyword=Calanthe sp. en-keyword=bean yellow mosaic virus kn-keyword=bean yellow mosaic virus en-keyword=clover yellow vein virus kn-keyword=clover yellow vein virus en-keyword=serological relationship kn-keyword=serological relationship END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=1-2 article-no= start-page=51 end-page=57 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Note on the parasitic fungus, Spicaria rubido-purpurea AOKI, on the potato tuber moth, Gnorimoschema opercullela (ZELL).

To elucidate their functions,targeted mutagenesis was performed by transformation with clened DNA in which the ORF was disrupted by insertion of a kanamycin resistancen gene cassette.Streak-purifications of a single colony of each transformant were repeatde to segregate homozygous mutants for disrupted copies, because Synechocystis PCC6803 was reported to have approximately 10 chromosomal DNA copies. Southern blot analysis revealed that mutants for ORF326 had not only disrupted ORF326 copies but also wild type ORF326 copies. This suggests that ORF326 is indispensable for growth under the mixotrophic growth condition used. However, mutants for frxC and mutants for ORF469 had only mutated copies, indicating that they dispensable for growth. Growth and chlorophyll a content of an ORF469-disrupted mutant were compared and chlorophyll a content of an ORF469-disrupted mutant were compared to those of wild type under mixotrophic growth condition, but no significant difference was detected. This indicates that ORF469 is required for neither normal growth nor chlorophyll biosynthesis under thie condition. en-copyright= kn-copyright= en-aut-name=OguraYutaka en-aut-sei=Ogura en-aut-mei=Yutaka kn-aut-name=小倉豊 kn-aut-sei=小倉 kn-aut-mei=豊 aut-affil-num=1 ORCID= en-aut-name=TakemuraMiho en-aut-sei=Takemura en-aut-mei=Miho kn-aut-name=竹村美保 kn-aut-sei=竹村 kn-aut-mei=美保 aut-affil-num=2 ORCID= en-aut-name=OdaKenji en-aut-sei=Oda en-aut-mei=Kenji kn-aut-name=小田賢司 kn-aut-sei=小田 kn-aut-mei=賢司 aut-affil-num=3 ORCID= en-aut-name=OhyamaKanji en-aut-sei=Ohyama en-aut-mei=Kanji kn-aut-name=大山莞爾 kn-aut-sei=大山 kn-aut-mei=莞爾 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Cyanobacteria kn-keyword=Cyanobacteria en-keyword=Gene disruption kn-keyword=Gene disruption en-keyword=Synechocystis PCC6803 kn-keyword=Synechocystis PCC6803 END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=33 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=トウモロコシに含まれるDIMBOAとアブラムシ抵抗性の関係 kn-title=The Relationship between DIMBOA Concentration in Corn Lines and Resistance to Aphids en-subtitle= kn-subtitle= en-abstract=ハイドロキサム酸のDIMBOAは特定のイネ科植物にあり、寄生する昆虫や病原菌に対して抵抗性物質となっている。一方、トウモロコシにはトウモロコシアブラムシとムギクビレアブラムシが寄生し、養分奪取、排泄する甘露によるスス病や萎縮病ウイルスの伝播者としての害をもたらしている。トウモロコシの21系統を1990年と1991年に栽培し、生育に伴うDIMBOA含量の消長とアブラムシの寄生の変化を調べた。DIMBOAは単位体重当り若齢期に多量を含有し、生育に伴って少量になり、老齢期になると検出不可能の量となった。使用した系統は全て多少ともアブラムシに対して抵抗性を示し、オオムギやコムギなどで見られた増殖は見られなかった。大増殖している農家の圃場から移植したが、DIMBOA含量の多い若齢期においては急速に死滅した。DIMBOA含量の少ない成熟期から老齢期にかけては若干管生存した。ムギミドリアブラムシを用いて、人工飼育液にDIMBOA等を添加して生存率を調べて、他の作用物質との関連を考察した。トウモロコシには同じ篩管に含有されるアコニット酸も多量にあり、両物質が共に抵抗性物質であると考えられた。 kn-abstract=2,4-Dihydrox-7-methoxy1,4-benzoxazin-3-one (DIMBOA), a hydroxamic acid is considered to be one of the components responsible for the resistance to pest insects in cereal plants. The relationship between concentration of DIMBOA and aphid infestation on 21 corn lines was investigated in 1990 and 1991. DIMBOA was detected in leaves od all corn lines tested, contained larger amounts in young plants and gradually decreased with growth. This property was the same as observed in wheat. A more than ten times difference in DIMBOA concentration was observed in corn lines. However, there was no positive correlation between DIMBOA concentration and aphid density. Most of the lines used had resistance to aphids.

The inheritance of seed flooding tolerance was also analyzed with a 6 x diallel cross. A large variation in seed flooding tolerance existed in the soybean germplasm as reflected in the germination rate which ranged from 0 to 100%. Most of the varieties tested were sensitive to seed flooding, and only 4% of the tested varieties showed a high tolerance (germination rate >90%). Seed flooding tolerance was controlled by both additive and dominance genes and a small number of effective factors and high narrow sense heritability in diallel analysis indicate that the selection for tolerance can effectively be done in early generations. en-copyright= kn-copyright= en-aut-name=HouFwu-Fenn en-aut-sei=Hou en-aut-mei=Fwu-Fenn kn-aut-name=侯福分 kn-aut-sei=侯 kn-aut-mei=福分 aut-affil-num=1 ORCID= en-aut-name=ThsengFu-Sheng en-aut-sei=Thseng en-aut-mei=Fu-Sheng kn-aut-name=曽富生 kn-aut-sei=曽 kn-aut-mei=富生 aut-affil-num=2 ORCID= en-aut-name=WuShu-Tu en-aut-sei=Wu en-aut-mei=Shu-Tu kn-aut-name=呉詩都 kn-aut-sei=呉 kn-aut-mei=詩都 aut-affil-num=3 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Glycine max kn-keyword=Glycine max en-keyword=Seed flooding tolerance kn-keyword=Seed flooding tolerance en-keyword=Diallel analysis kn-keyword=Diallel analysis en-keyword=Germination kn-keyword=Germination en-keyword=Varietal kn-keyword=Varietal en-keyword=difference kn-keyword=difference END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=1-2 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=1965 dt-pub=196512 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A virus disease of pea caused by white clover mosaic virus. kn-title=White clover mosaic virusによるエンドウのウイルス病 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=InouyeT. en-aut-sei=Inouye en-aut-mei=T. kn-aut-name=井上忠男 kn-aut-sei=井上 kn-aut-mei=忠男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=1 cd-vols= no-issue=1 article-no= start-page=35 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Absorption of Iron by MuSty-Odor Producing Cyanobacteria (Anabaena macrospora, Phormidium tenue, Oscillatoria tenuis and Oscillatoria brevis) kn-title=かび臭物質産生ラン藻類Anabaena macrospora, Phormidium tenue, Oscillatoria tenuis 及びOscillatoria brevisの鉄吸収 en-subtitle= kn-subtitle= en-abstract=A recent problem for water utilities is musty-odor, which is caused by geosmin or 2-methylisoborneol produced by cyanobacteria. In order to clarify the mechanism of growth of musty-odor producing cyanobacteria, the effect of iron on the growth of Anabaena macrospora, Phormidium tenue, Oscillatoria tenuis and Oscillatoria brevis was studied. The growth of A. macrospora, P. tenue and O. tenuis was suppressed at low levels of iron (colloidal iron, 1 μM as Fe) in the EDTA-free CT medium. However, at high levels of iron (18 μM as Fe) using colloidal iron kept in a refrigerator, A. macrospora and P. tenue were able to grow although O. tenuis could not. When autoclaved colloidal iron was used as the iron source, none of the cyanobacteria except O. brevis were able to grow. The effect of spongy or powdery iron on the growth of cyanobacteria was also investigated. A. macrospora, P. tenue and O. brevis were capable of growing in media containing spongy or powdery ion, which release Fe(U) continuously, but the growth of O. tenuis was suppressed. The culture experiments and photoreduction of Fe(V) to Fe(U) show that A. macrospora, P. tenue and O. brevis can utilize iron even in the absence of EDTA if there are large amounts of iron present in a form photoreducible to Fe(U). However, O. tenuis was found to require chelated and photoreducible iron for its growth. The present results and previous studies {Nogaku Kenkyu, 62:253-270(1991)} indicate that O. brevis has the ability to utilize a wide variety of iron forms such as Fe(V)-EDTA, Fe(U)-BPDS, Fe(V)-Desferrioxamine B(microbial siderophore) chelates, colloidal iron, iron oxides (Fe2O3, Fe3O4), spongy iron and powdery iron. On the other hand, O. tenuis seems to have very specific requirements for the from of iron it can utilize for growth. kn-abstract=近年、琵琶湖の南湖をはじめ、霞々浦や相模湖など多くの湖沼や水道水源地において、人間活動に付随すると富栄養化問題となり、ラン藻類、特にかび臭物質を産生するラン藻の発生が憂慮されている。琵琶湖を水源とする大津、京都、大阪、神戸など関西の各都市の水道では、同湖で毎年発生するラン藻、すなわちAnabaena macrospora｛ジオスミン（geosmin）を産生｝やPhormidium tenue, Oscillatoria tenuis｛2-メチルイソボルネオール（2-methylisoborneol, MIB）を産生｝などが作り出すこれらのかび臭物質（ジオスミンまたはMIB）による水道水の異臭味が大きな問題となっている。こうした水圏環境における異臭味は世界各地でも問題となり、近年この問題に関する国際シンポジウム（International Symposium on Off-Flavors in the Aquatic Environment）が開かれるようになり、1982年6月には第1回（ヘルシンキ）、1987年10月には第2回（鹿児島）、そして1991年3月には第3回（ロサンゼルス）のシンポジウムがそれぞれ開催された。しかしこうしたラン藻が異常増殖する要因はまだ明らかではない。そのためかび臭物質を産生するラン藻類の発生を予測あるいは抑制する情報に関する研究は強い要請があるにもかかわらずあまり進展をみていない。 en-copyright= kn-copyright= en-aut-name=NakashimaSusumu en-aut-sei=Nakashima en-aut-mei=Susumu kn-aut-name=中島進 kn-aut-sei=中島 kn-aut-mei=進 aut-affil-num=1 ORCID= en-aut-name=AoyamaIsao en-aut-sei=Aoyama en-aut-mei=Isao kn-aut-name=青山勲 kn-aut-sei=青山 kn-aut-mei=勲 aut-affil-num=2 ORCID= en-aut-name=YagiMasakazu en-aut-sei=Yagi en-aut-mei=Masakazu kn-aut-name=八木正一 kn-aut-sei=八木 kn-aut-mei=正一 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=3 article-no= start-page=161 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=1976 dt-pub=19760228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Chemical investigation on inorganic constituents in night soil (excreta) II.

There are resistant lines and susceptible lines in barley to aphids. The changing amounts of gramine from seeding to mature stages were investigated on 27 lines from 1989 to 1991. Barley was sown aound November 20 in the year and harvested in early June. Higher amount of gramine in seeding stage in all lines were detected,then gradually decreased with barley growth until 2 to 3 weeks before the earing stages. At this time aphids had appeared on the barley leaves and increased in population. The susceptible lines had a tendency of greater decrease in gramine content than the resistant lines at the time of aphid population growth. The maximum aphid population was observed from the end of April to early May. The gramine content was almost constant this time. The degradation mechanisms may be important factors determining the defference of resistant and susceptible lines at the aphid population growth stage. The susceptible lines may have a higher activity of degradation mechanism. en-copyright= kn-copyright= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=1 ORCID= en-aut-name=RustamaniMaqsood A. en-aut-sei=Rustamani en-aut-mei=Maqsood A. kn-aut-name=RustamaniMaqsood A. kn-aut-sei=Rustamani kn-aut-mei=Maqsood A. aut-affil-num=2 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=3 ORCID= en-aut-name=KasaharaToshihiko en-aut-sei=Kasahara en-aut-mei=Toshihiko kn-aut-name=笠原敏彦 kn-aut-sei=笠原 kn-aut-mei=敏彦 aut-affil-num=4 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 en-keyword=Gramine content kn-keyword=Gramine content en-keyword=Barley kn-keyword=Barley en-keyword=Aphid kn-keyword=Aphid en-keyword=Resistant lines kn-keyword=Resistant lines en-keyword=Susceptible lines kn-keyword=Susceptible lines END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=17 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Quantitative Variations of a Resistance Substance, DIMBOA, against Aphids in Wheat Varieties. kn-title=アブラムシ抵抗性物質，DIMBOA, のコムギにおける消長 en-subtitle= kn-subtitle= en-abstract=コムギもオオムギと同様に系統・品種によってアブラシによる寄生の程度に差がみられた。数百のコムギ品種について、寄生程度の調査を1989年に予備的に行い、選別した8品種について、1990年と1991年にコムギの抵抗性物質とされているDIMBOAの消長を調べた。寄生程度の比較調査は1989年から1992年まで調べ、年と場所による変動を調べた。数千のオオムギの系統間においてはアブラムシ類の寄生数で百倍以上の差があり、抵抗性と感受性の系統を容易に選別できている。しかし、コムギにおいては数十倍の寄生数を示す系統は見出せなかった。系統間に年と場所での抵抗性と感受性の差が見られても、遺伝的であることが確認された系統はなかった。オオムギと比較して、供試した数百のコムギ系統の中には、アブラムシの寄生が非常に多い感受性系統はなく、供試した全てが多少とも抵抗性の形質を示した。コムギの抵抗性物質であるDIMBOAは冬期2月下旬で約1μg/g新鮮葉の含量であり、生育に伴って減少した。減少の程度は系統間で差が余りなかった。換言するとDIMBOAのない、あるいは極端に少量の系統はなく、全ての系統で抵抗性の一因となっていると考察された。コムギにおいては、オオムギで顕著な抵抗性物質と考えられているインドールアルカロイドのグラミンは検出されなかったが、オオムギで検出されなかったDIMBOAが顕著な抵抗性成分として検出され、これによって両ムギの質的な差異が示された。コムギはもう一つの抵抗性物質である水溶性のアコニット酸をオオムギの約10倍も含有しており、コムギではDIMBOAとアコニット酸の両者がアブラムシ抵抗性物質として作用していると考えられた。 kn-abstract=Aphids sometimes severely infest wheat plants, mainly sucking phloem sap and disrupting tissues, and in a few cases act as virus vectors. There are resistant and susceptible varieties of wheat against aphids. DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) is a substance causing resistance to animals including aphids. The change in the amounts of DIMBOA with growth in eight wheat varieties was estimated in 1990 and 1991. Wheat seeds were sown at mid-November in the former year and harvested in mid-June. Aphids appeared from early April, increased with the growth of the wheat, and finally decreased with the senescence of the wheat. Rhopalosiphum maidis appeared early in the season, R. padi appeared late, Schizaphis graminum and Sitovion akebiae appeared intermittently in the season. S. graminum appeared more frequently on wheat than barley. DIMBOA was detected from wheat but not from barley. Gramine (N,N-dimethyl-indole-3-methanamine) was detected from barley, and is known as an important resistance substance. However gramine could not be detected in wheat. DIMBOA was found in higher amounts in young wheat, and gradually decreased with growth. A clear relationship between the aphid population and DIMBOA amounts could not be observed. However, all the wheat varieties used in this experiment seemed to have resistance against aphids. The resistance was compared with barley susceptible lines. DIMBOA was presumed to share the property of resistance with aconitic acid in wheat. en-copyright= kn-copyright= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=1 ORCID= en-aut-name=Awan RustamaniMaqsood en-aut-sei=Awan Rustamani en-aut-mei=Maqsood kn-aut-name=Awan RustamaniMaqsood kn-aut-sei=Awan Rustamani kn-aut-mei=Maqsood aut-affil-num=2 ORCID= en-aut-name=ChengWen-Yi en-aut-sei=Cheng en-aut-mei=Wen-Yi kn-aut-name=鄭文儀 kn-aut-sei=鄭 kn-aut-mei=文儀 aut-affil-num=3 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=4 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 en-keyword=DIMBOA content kn-keyword=DIMBOA content en-keyword=Wheat kn-keyword=Wheat en-keyword=Aphid kn-keyword=Aphid en-keyword=Resistant varaity kn-keyword=Resistant varaity en-keyword=Susceptible variety kn-keyword=Susceptible variety END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=149 end-page=157 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Increase in Cytochorome c and a 11.9 kDa protein in Submerged Rice Seedlings after Exposure to Air kn-title=イネ水中芽生えの酸素適応過程におけるチトクロムcと１１．９kDaタンパク質の増加 en-subtitle= kn-subtitle= en-abstract=イネ水中芽生えを空気に触れさせた後のチトクロムc含量の変動を調べるために、米ぬかから精製したチトクロムcを用いて抗チトクロムc血清を作成した。ウェスタンプロット分析によると、水中芽生えにはチトクロムcは検出されなかったが、空気に触れてから6時間以降に検出された。酸素適応24時間の芽生えには生重量あたりで好気対照と同レベルのチトクロムcが存在した。抗血清作成の抗原として用いたチトクロムc標品は、A408/A280比の値（4.66）が高いことから、よく精製されていると考えられるが、抗血清はいくつかの他のポリペプチドと反応した。そのうちの一つはチトクロムcよりも抗血清に強く反応し、その分子量は11.9kDaであった。このポリペプチドは酸素適応過程で増加し、水中芽生えや好気対照では24時間酸素適応芽生えよりも少なかった。 kn-abstract=To examine the changes in cytocrome c content in submerged rice seedlings after exposure to air, antiserum was prepared against purified cytocrome c from rice bran. Western blottong analysis revealed that cytochrome c was detected 6 h after exposure to air, but not detected in submerged rice seedling. On a fresh weight basis, the same level of cytochrome c as that of the aerobic control was found in the 24-h-air adapted seedlings. judging from the high A408/A280 ratio (4.66),the cytochrome c preparation used as antigen was considered to be well purified. However, the antiserum reacted other several polypeptides. One of them reacted more strongly against the antisermu than cytochrome c and its molecular weight was estimated as 11.9 kDa. The polypeptide increased during air adaptation and the levels found in both submerged seedlings and aerobic control were lower than that in 24-h-air-adapted seedlings. en-copyright= kn-copyright= en-aut-name=ShibasakaMineo en-aut-sei=Shibasaka en-aut-mei=Mineo kn-aut-name=柴坂三根夫 kn-aut-sei=柴坂 kn-aut-mei=三根夫 aut-affil-num=1 ORCID= en-aut-name=UshimaruTakashi en-aut-sei=Ushimaru en-aut-mei=Takashi kn-aut-name=丑丸敬史 kn-aut-sei=丑丸 kn-aut-mei=敬史 aut-affil-num=2 ORCID= en-aut-name=OokuboKatsuyuki en-aut-sei=Ookubo en-aut-mei=Katsuyuki kn-aut-name=大久保勝之 kn-aut-sei=大久保 kn-aut-mei=勝之 aut-affil-num=3 ORCID= en-aut-name=TsuchidaShin-ichi en-aut-sei=Tsuchida en-aut-mei=Shin-ichi kn-aut-name=土田進一 kn-aut-sei=土田 kn-aut-mei=進一 aut-affil-num=4 ORCID= en-aut-name=TsujiHideo en-aut-sei=Tsuji en-aut-mei=Hideo kn-aut-name=辻英夫 kn-aut-sei=辻 kn-aut-mei=英夫 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 en-keyword=Air-adaptation kn-keyword=Air-adaptation en-keyword=Anti-cytochrome c serum kn-keyword=Anti-cytochrome c serum en-keyword=Cytochrome c kn-keyword=Cytochrome c en-keyword=Cytocrome c purification kn-keyword=Cytocrome c purification en-keyword=Oryza sativa kn-keyword=Oryza sativa END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=135 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Changes in Mitochondrial Spectra of Submerged Rice Seedlings after Exposure to Air Gaussian Deconvolution Analysis kn-title=イネ水中芽生えの酸素適応過程におけるミトコンドリアスペクトルの変化Gaussian Deconvolutionによる解析 en-subtitle= kn-subtitle= en-abstract=吸収スペクトルをカーブアナリシスの手法を用いて解析し、水中で発芽した芽生えが空気に触れたときに生じるミトコンドリアチトクロム類の量的変化を調べた。アンチマンイシンA存在下でのコハク酸還元による差スペクトルには3種のチトクロムbが見出されるが、チトクロムc1とよく似た成分がかなりの寄与で存在していることが判った。その寄与を除くといずれの芽生えから単離したミトコンドリアにおいても、3種のチトクロムbは互いにほとんど同程度の吸収を示した。また、水中芽生え、酸素適応芽生え、好気芽生えから単離したミトコンドリアの間には、3種いずれのチトクロムbの吸収（タンパク質当たり）に関しても差がなかった。チトクロムcは水中芽生えでは好気芽生えの約半分の量が存在し、酸素適応過程で1.5倍に増加した。これはチトクロムaa3の変化と全く同じであった。チトクロム類の中には、酸素適応過程において酸素に対する応答の異なる2つのグループが存在することを示した。 kn-abstract=Quantitative changes in mitochondrial cytochromes of submerged rice seedlings after exposure to air were investigated using gaussian deconvolution analysis on absorption spectrum at liquid nitrogen temperature. Differnece spectra were obtained from subtracting the absorption spectra of oxidized mitochondria from reduced mitochondria by succinate with antimycin-A. they showed three kinds of b-type cytochrome and a spectral component similar to cytochrome c1. Subtraction of the cytochrome c1-like component from the spectrum by curve analysis showed that three cytochrome bs had similar absorption maximum and that on a mitochondrial protein basis they were constant during air-adaptation. Cytochrome c per mitochontorial protein in submerged seedlings was about half of that in aerobic seedlings and increased by 1.5-fold during air-adaptation. The change in cytochrome c content was in paralleled with that of cytochrome aa3. These findings revealed that there were two groups of cytochromes in the response to air-adaptation,i.e.,three cytochrome bs were constant and cytochoromes c and aa3 increased in parallel. en-copyright= kn-copyright= en-aut-name=ShibasakaMineo en-aut-sei=Shibasaka en-aut-mei=Mineo kn-aut-name=柴坂三根夫 kn-aut-sei=柴坂 kn-aut-mei=三根夫 aut-affil-num=1 ORCID= en-aut-name=TsujiHideo en-aut-sei=Tsuji en-aut-mei=Hideo kn-aut-name=辻英夫 kn-aut-sei=辻 kn-aut-mei=英夫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Absorption spectrum kn-keyword=Absorption spectrum en-keyword=Air-adaptation kn-keyword=Air-adaptation en-keyword=Cytocrome kn-keyword=Cytocrome en-keyword=Gaussian deconvolution analysis kn-keyword=Gaussian deconvolution analysis en-keyword=Oryza sativa kn-keyword=Oryza sativa END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=1999 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of Turbulent Fluxes by Gradient Method with Surface Temperatures of Rice Plant Canopy kn-title=イネ群落表面温度を用いた傾度法による乱流輸送量の推定 en-subtitle= kn-subtitle= en-abstract=1997年夏季にイネ群落で、微細気象観測とともに、イネ群落の表面温度の測定を行った。得られた観測資料とイネ群落表面温度を用いてイネ群落上の乱流輸送量の推定を行った。結果は以下のように要約される。イネ群落上では、ほぼ全期間に亘って中立に近い安定な温度成層を形成し、日中には顕熱輸送量に比較して潜熱輸送量が格段に大きかった。熱映像温度計で測定されたイネ群落の表面温度から、群落上の顕熱輸送量と、植物の蒸散量と密接に関係する群落上の潜熱輸送量の推定を試みた。渦相関法で計算された顕熱輸送量とイネ群落表面温度から計算された顕熱輸送量と比較した。データのばらつきは大きいが、相関係数（R）の値は、0.79で、ほぼ1対1に対応していることが分かった。またイネ群落の表面で、水蒸気圧が飽和していると仮定し、イネ群落表面温度から、潜熱輸送量を推定すると、渦相関法で計算された潜熱輸送量よりも日中に2倍以上も過大評価されることが分かった。イネ群落直上で実測された水蒸気圧から、イネ群落表面の位置に相当する比湿を推定し、傾度法を用いて計算された潜熱輸送量が、渦相関法で得られた潜熱輸送量に、ほぼ1対1の対応をすることが分かった。また両者の間には、0.98と非常に高い相関関係が得られた。ここで行った計算には、尚幾つかの仮定が含まれているが、イネ群落の表面温度を用いて、顕熱、潜熱輸送量を推定する新たな評価法の一つとして今後利用できると期待される。 kn-abstract=Micrometeorological observations including turbulent fluxes and canopy surface temperatures were made in paddy in the summer of 1997. The sensible and latent heat fluxes were estimated by the gradient method under the assumption of similarity between the turbulent exchange coefficient for momentum and that for heat and water vapor. The surface temperatures measured by a thermal imager and water vapor pressures estimated from surface temperatures and relative humidity were used for temperature and water vapor at the height(d+z0) of U=0, where d is the displacement height, z0 the roughness length and U the mean wind velocity. The sensible and latent heat fluxes estimated by the gradient method depicted typical diurnal varietions. The turbulent fluxes by the present method and eddy correlation method showed fairly good agreement, especially for latent heat fluxes. These results confirmed that this method is a promising one. en-copyright= kn-copyright= en-aut-name=MiyashitaKoichi en-aut-sei=Miyashita en-aut-mei=Koichi kn-aut-name=宮下晃一 kn-aut-sei=宮下 kn-aut-mei=晃一 aut-affil-num=1 ORCID= en-aut-name=MaitaniToshihiko en-aut-sei=Maitani en-aut-mei=Toshihiko kn-aut-name=米谷俊彦 kn-aut-sei=米谷 kn-aut-mei=俊彦 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Surface temperature kn-keyword=Surface temperature en-keyword=Rice plant canopy kn-keyword=Rice plant canopy en-keyword=Thermal imager kn-keyword=Thermal imager en-keyword=Turbulent fluxes kn-keyword=Turbulent fluxes END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=2 article-no= start-page=117 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Differences in the Responses to Iron Deficiency Stress between Bean and Maize kn-title=インゲンとトウモロコシの鉄欠乏ストレスに対する反応の差異 en-subtitle= kn-subtitle= en-abstract=インゲンとトウモロコシを用い、鉄欠乏ストレスに対する両植物の反応の差異について検討した。その結果は以下のように要約できる。1)鉄欠乏ストレスに対して、インゲンの感受性は小さく、トウモロコシの感受性は大きかった。換言すれば、インゲンの鉄欠乏耐性は大きく、トウモロコシの鉄欠乏耐性は小さいということができる。2）鉄欠乏ストレスを受けたとき、インゲン根は鉄還元能と培地pH低下能を発現したが、トウモロコシ根ではそのような反応はほどんど認められなかった。3)鉄欠乏ストレスによるインゲン根での鉄還元能と培地pH低下能の発現は遮光処理、植物体地上部の切断処理、あるいは代謝阻害剤（DNP）の添加によって抑制された。4)鉄無添加処理はその後のインゲン植物体の鉄吸収を著しく促進した。トウモロコシではそのような現象は認められなかった。したがって、インゲンの鉄欠乏耐性が大きいのは、鉄欠乏ストレスによってインゲン根で鉄還元能と培地pH低下能が発現することによるものと考えられる。 kn-abstract=The responses to iron deficiency stress in bean and maize were compared. The susceptibility to iron deficiency stress was smaller in bean than in maize;i.e., the tolerance to iron deficiency was greater in bean than in maize. The roots of the bean plants exposed to iron deficiency stress, developed iron reducing capacity and medium-pH lowering capacity,but not the roots of maize. The iron reducing capacity and medium-pH lowering capacity of the bean roots were inhibited by a shadowing, detopping, and the addition of 2,4-dinitrophenol. Iron absorption in the bean plants was stimulated by the pretreatment without iron in the growth medium, but not in the maize plants.

OFV caused systemic infection in Calanthe, Chenopodium quinoa and Beta vulgasis var. cicla, and local infection in C.amaranticolor, C. murale, Spinacia oleracea, Tetragonia expansa, Nicotiana tabacum, N. clevelandii, N. glutinasa, N. rustica, Vigna unguiculata. C quinoa and T expansa are useful as indecator hosts and as a source of virus for inoculation, diagnosis and purification. Sap from C. quinoa was infective after dilution to 10-3 but not 10-4, after 10 min at 45 but not 50℃, and after 1 hr at 20℃ but not 2 hrs. For sap inoculation, it is best to use the homogenate of OFV-onfected leaves within about 7-8 min after homogenization in summer and within about 15 min in winter. The virus particles were bullet-shape or bacilliform, approximately 45-50×105-125 nm in a negatively stained praparations. In ultrathin sections, the viroplasms were observed in the nuclei, and the virus particles and the chracteristic spokewheel structures were found both in the nuclei and the cytoplasm. Antiserum (precipitin tiner:1/512) against the present virus reacted strongly with the isolates of OFV-Cy-50, similar to that of homologous virus. In agar gel diffusion tests, no spur formation occurred among Cal. 94-16 and OFV-Cy-50. In SDS-polyacrylamide gel electrophoresis, one major band of Mr 55,000, probably viral nucleocapsid-protein, and three minor proteins were detected, similar to those of OFV･So from Cymbidium. en-copyright= kn-copyright= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=1 ORCID= en-aut-name=MatsumotoJun-ichi en-aut-sei=Matsumoto en-aut-mei=Jun-ichi kn-aut-name=松本純一 kn-aut-sei=松本 kn-aut-mei=純一 aut-affil-num=2 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=3 ORCID= en-aut-name=MitsuhataKoji en-aut-sei=Mitsuhata en-aut-mei=Koji kn-aut-name=光畑興二 kn-aut-sei=光畑 kn-aut-mei=興二 aut-affil-num=4 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name=近藤秀樹 kn-aut-sei=近藤 kn-aut-mei=秀樹 aut-affil-num=5 ORCID= en-aut-name=TaharaMochimu en-aut-sei=Tahara en-aut-mei=Mochimu kn-aut-name=田原望武 kn-aut-sei=田原 kn-aut-mei=望武 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 affil-num=5 en-affil= kn-affil=岡山大学 affil-num=6 en-affil= kn-affil=岡山大学 en-keyword=Calanthe kn-keyword=Calanthe en-keyword=Orchid fleck virus kn-keyword=Orchid fleck virus en-keyword=Calanthe yellowish fleck disease kn-keyword=Calanthe yellowish fleck disease END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=2 article-no= start-page=187 end-page=199 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Some Properties of Cymbidium Mosaic Virus Isolated from Calanthe spp. kn-title=エビネ（Calanthe spp.）から分離されたCymbidium mosaic virus en-subtitle= kn-subtitle= en-abstract=1986年、1990年および1993年に採集したモザイクを示すエビネからcymbidium mosaic virus（CyMV）を検出して同定し、諸性質を調べた。本ウイルスは汁液接種により供試した9科37種のうち、エビネとゴマに全身感染し、ツルナなど6科11種に局部感染した。しかし、分離株によってキュウリやセンニチコウの接種葉に感染するものと感染しないものがあった。ツルナ病葉粗汁液中での安定性は耐熱性65〜70℃、耐希釈性10-5〜10-6、耐保存性1〜2ヶ月であった。DN法試料の電顕観察では長さ約475nmのウイルス粒子が観察された。ウイルス外被タンパク質の分子量は約27,800であり、既報のCyMVの値とほぼ同じであった。ツルナ感染葉中の感染に特異的な二本鎖RNAの電気泳動ではreplicative form と思われる4.43×106と3.84×106のバンドが認められた。エビネから分離されたCyMV分離株は直接二重酵素結合抗体法（DAS−ELISA）で、Cy−16分離株の抗血清とよく反応するものが多かったが、反応が弱く、抗原性に若干の違いがあるものが存在した。 kn-abstract=Cymbidium mosaic virus(CyMV) was isolated from Calanthe spp. showing mosaic on the leaves, collected in Yamaguchi and Kyoto Prefectures in 1986〜1993.

selection and hybridization among progeny isolates derived from a cross between two strains of barley mildew originally avirulent to wheat and Agropyron has given rise to isolates virulent on those plants. Barley mildew isolates h9 and Hna were hybridized on a susceptible barley host Kuromugi 148 to produce perithecia. After meiosis a number of haploid ascospores developed in the diploid perithecium. The resulting ascospores were inoculated onto Kuromugi 148 to develop conidiospores. Conidiospores sampled from 100 disease lesions were separately inoculated onto 100 seedligs of Kuromugi 148 and single conidiospores collected from each seedling were individually inoculated onto 100 seedlings of Kuromugi 148 to establish 100 progeny isolates. For evaluating pathogenicity of the isolates, conidiospores sampled from each isolate were inoculated onto 100 seedlings each of wheat cultivars Norin 52 and Norin 61, Agropyron Ag. E. e. and Ag. S. 4. The most virulent among the 100 isolates were selected and hybridized again on Kuromugi 148 to produce the next generation. This cycle of hybridization and selection was repeated four times. In the first generation, which was not subjected to selection, most of the isolates showed no or very weak growth on the non-host wheat and Agropyron plants. In the second generation which was derived from hybridization between the most virulent isolates of the first generation, some of the progenies showed weak virulence on the whear or Agropyron plants. In the succeeding generations the degree of virulence on the wheat or Agropyron plants increased gradually in response to selection. After four cycles of hybridization and selection some isolates developed highly virulent symptoms on the originally resistant wheat and Agropyron non-host plants. This increased virulence on wheat and Agropyron plants may be due to the recombination and segregation of minor genes promoting virulence derived from the parents h9 and Hna which were originally avirulent on both wheat and Agropyron. Our results indicate that new virulent mildew isolates may develop in nature after hybridization between two avirulent isolates. kn-abstract=イネ科植物うどんこ病菌（Erysiphe graminis DC.）はコムギ、オオムギ、カモジグサ、ライムギなど多くのイネ科植物に寄生するが、それぞれの菌は宿主特異性によっていくつかのformae specialesに分化しており、例えば、オオムギうどんこ病菌はオオムギ属以外の植物には感染しないといわている。しかしながら、Cherewickはイネ科植物うどんこ病菌について、元々の宿主とは異なる植物に接触する交互接種を試み、カモジグから分離したうどんこ病菌がコムギを犯す事例を見出した。またHardisonはいろいろなイネ科植物から分離したうどんこ病菌を用いて多くの交互接種を行った結果、ほとんどの菌株は2つあるいはそれ以上の属の植物に病原性を持っていることを認めた。さらに、日浦および日浦と部田はコムギうどんこ病菌とカモジグサうどんこ病菌の種間交雑によって得られた後代から、コムギあるいはカモジグサのいずれかに病原性を持つ菌株はもちろん、コムギとカモジグサの両方に病原性を持つ新しい菌株も容易に作れることを報告した。一方、これらの分化型の中にはそれぞれの宿主の品種あるいは系統に対して病原性の異なる多くのphysiologic raceが分化しており、それらの宿主-病原関係には、いわゆるgene for gene仮設が適合すると考えられている。しかしながら、部田はオオムギうどんこ病菌抵抗性遺伝子JMlsnに対して病原性のない菌株h9とH14の交雑後代からJMlsnに病原性のある菌株を作出した。これらの事実はうどんこ病における宿主-病原菌の相互作用が単純な主働遺伝子によるgene for gene仮設では説明し切れないことを示しており、このような非病原性菌株間の交雑後代から病原性のある菌株が脈生する遺伝的な機構を解明することは、うどんこ病抵抗性育種を進める上でも極めて重要であると思われる。 en-copyright= kn-copyright= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=4 article-no= start-page=279 end-page=286 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Production of Virulent Hybrid Progenies to Hordeum spp. with Resistant Gene JMlsn by Crossing between Two Avirulent Isolates of Erysiphe graminis DC. f. sp. hordei kn-title=オオムギうどんこ病抵抗性遺伝子JMlsnに対する非病原性菌株間の交雑による病原性菌糸の作出 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=11 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reaction of the Resistant Gene ml-o to Various Barley Powdery Mildew Strains kn-title=オオムギうどんこ病抵抗性遺伝子ml-oの各種菌株に対する反応 en-subtitle= kn-subtitle= en-abstract=うどんこ病抵抗性遺伝子ml-oを持つ7つの突然変異系統と原品種に対して圃場で採取したうどんこ病菌4菌株と交雑由来の4菌株計8菌株を接種し、ml-oの突然変異系統とその原品種のうどんこ病菌に対する反応を比較した。供試8菌株は判別品種に対して相互に異なる反応を示し、従って異なる病原性遺伝子を持つものとみられた。一方、7つの原品種は8つの菌株に対する反応が一般的に良く似ており、抵抗性に関する遺伝的背景が似通っているとみられた。ml-oを持つ突然変異体とその原品種を比較すると、一部の例外を除けば病斑型はほとんど等しい一方、病斑数が顕著に減少していたので、ml-oは病斑型に対してではなく、病斑数を減少させる方向に働くとみられる。 kn-abstract=Eight powdery mildew strains, four collected from the field and the other four derived from a cross between two strains, were inoculated to seven mutant barley lines having the ml-o gene for powdery mildew resistance and their original varieties of barley. These eight powdery mildew strains showed a distinctive reaction to the nine testers having various resistant genes. Onthe other hand, the original barley varieties showed a similar reaction to all the powdery mildew strains inoculated, indicating that the genetic background of these varieties was similar. In comparison with the ml-o mutants and their original varieties, the type of lesion did not change in most cases, but the number of lesions decreased significantly without exception. In conclusion, the powdery mildew resistant gene ml-o does not affect the type of lesions but it reduces the number of lesions. en-copyright= kn-copyright= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Powdery mildew resistance kn-keyword=Powdery mildew resistance en-keyword=Barley kn-keyword=Barley en-keyword=ml-o gene kn-keyword=ml-o gene en-keyword=Pathogenicity kn-keyword=Pathogenicity END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=69 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=1997 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=QTL Mapping for Powdery Mildew (Erysiphe graminis DC. f. sp. hordei EM Marchal) Resistance in Barley (Hordeum vulgare L.) kn-title=オオムギうどんこ病抵抗性遺伝子のＱＴＬマッピング en-subtitle= kn-subtitle= en-abstract=オオムギ品種Steptoe×Morex (S/M)およびHarrington×TR306 (H/T)の2交雑組合せからバルボッサム法によって育成された倍加半数体（DH）系統を用い、オオムギうどんこ病菌h81、h83（S/M）、h9、h4およびk6（H/T）に対する抵抗性を調べ、抵抗性のデータとマーカー情報からオオムギうどんこ病抵抗性を支配する遺伝子の位置と効果をQTLマッピングにより推定した。その結果、S/Mでは各菌株に対して特異的に発現するいくつかの抵抗性遺伝子が4H、5H、6H、および7Hに見出された。一方、H/Tにおいてはいずれの菌株に対してもDH系統群の抵抗性スコアの分離比が抵抗性：罹病性＝1：1に適合し、見出された遺伝子は抵抗性遺伝子Mlgと同一あるいは同座であるとみられた。 kn-abstract=Powdery mildew, caused by Erysiphe graminis DC. f. sp. hordei EM Marchal, is a serious disease of Barley (Hordeum vulgare L.). In this study, we used molecular markers to identify the chromosomal locations carrying genes for powdery mildew resistance and to estimate the effect of each gene. Doubled haploid lines derived from Steptoe×Morex (S/M), Harrington×TR306 (H/T) and their parental were inoculated with five powdery mildew strains. Several quantitative trait loci (QTL) controlling E. graminis resistance were found and lacated on chromosome 4H, 5H, 6H and 7H in S/M. On the other hand, no QTL was detected in H/T but Harrington had a major resistant gene (Mlg) for powdery mildew resistance. Maker-assisted selection was conducted to examine the effect of accumulation for mildew resistance. There was a significant interaction between QTLs lacated in 4H and 7H, which suggested the presence of an epistatic effect between these QTLs. en-copyright= kn-copyright= en-aut-name=IwasaTomohiko en-aut-sei=Iwasa en-aut-mei=Tomohiko kn-aut-name=岩佐友彦 kn-aut-sei=岩佐 kn-aut-mei=友彦 aut-affil-num=1 ORCID= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=2 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Hordeum vulgare kn-keyword=Hordeum vulgare en-keyword=Erysiphe graminis kn-keyword=Erysiphe graminis en-keyword=QTL mapping kn-keyword=QTL mapping en-keyword=DH lines kn-keyword=DH lines END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=3 article-no= start-page=113 end-page=124 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effects of two kinds of very early genes on yield and its components in barley kn-title=オオムギにおける2種の極早生遺伝子の収量とその構成要素に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YasudaS. en-aut-sei=Yasuda en-aut-mei=S. kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=1 ORCID= en-aut-name=HayashiJ. en-aut-sei=Hayashi en-aut-mei=J. kn-aut-name=林二郎 kn-aut-sei=林 kn-aut-mei=二郎 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=69 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Character Expression and Inheritance of a "Short Upper Leaves" Mutant in Barley kn-title=オオムギにおける上位葉短縮型変異体の形質表現と遺伝性 en-subtitle= kn-subtitle= en-abstract=二条オオムギ品種ふじ二条にガンマー線を3代にわたって合計90KR累代照射した後代から上位の数葉が短縮し、特に止葉は痕跡的に短くなる変異体を見出し、その形質表現と遺伝性を解析した。1）この変異体では基部の数枚の葉身の長さは原品種と変わらず、上位の数葉、特に止葉が強く短縮する。穂長および小穂段数は原品種と変わらない。2）この変異体は不完全優性の主働遺伝子Sul（short upper leaves上位葉短縮型）に支配される。3）Sul遺伝子は第2染色体に座乗するν/V（条性）遺伝子と連鎖し、また相互転座点と密接に連鎖している。4）この変異体は登熟期における葉面積が小さいので相互遮蔽が少なく、また収穫指数が高まって多肥密植栽培で多収となる可能性があり、また、蒸散量が少なく、半乾燥条件に適応することが期待される。 kn-abstract=A mutant which devolops an extremely shortened flag leaf and shorter upper leaves was obtained from the progeny of 90 KR of gamma-ray irradiated Fuji Nijo, a malting barley variety. This mutant was controlled by a single partial dominant gene named Sul (short upper leaves). The character expression and the inheritance of the gene were investigated in this study. Sul shortened the flag leaf and upper several leaves and uppermost internode length, while it did not affect the length of spike, lower leaves and the second or lower internodes. A reciprocal translocation of the chromosomes was observed in this mutant line, and the Sull gene was linked with the V (two-rowed) gene on chromosome 2, and also linked with the breaking point of the reciprocal translocation. Small leaf area caused by the Sull gene might reduce the mutual shading and the transpiration of the leaf canopy at the later growth stages. en-copyright= kn-copyright= en-aut-name=KanataniRyoichi en-aut-sei=Kanatani en-aut-mei=Ryoichi kn-aut-name=金谷良一 kn-aut-sei=金谷 kn-aut-mei=良一 aut-affil-num=1 ORCID= en-aut-name=WuJiri en-aut-sei=Wu en-aut-mei=Jiri kn-aut-name=呉基日 kn-aut-sei=呉 kn-aut-mei=基日 aut-affil-num=2 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Plant type kn-keyword=Plant type en-keyword=Linkage analysis kn-keyword=Linkage analysis en-keyword=Developmental pattern kn-keyword=Developmental pattern END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=3 article-no= start-page=195 end-page=220 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=198703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Character Expression and Inheritance of ‘Irregulare’ Spike in Barley kn-title=オオムギにおける不斉条穂の形質発現と遺伝 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=1 ORCID= en-aut-name=SaitoWataru en-aut-sei=Saito en-aut-mei=Wataru kn-aut-name=斉藤渉 kn-aut-sei=斉藤 kn-aut-mei=渉 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=23 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Varietal Variation of Earliness in a Narrow Sense and Its Significance for Adaptation in Barley kn-title=オオムギにおける純粋早晩性の品種変異と適応的意義 en-subtitle= kn-subtitle= en-abstract=本研究ではオオムギの出穂早晩性に関与する内的要因のひとつである純粋早晩性の品種変異とその地理的差異について検討するとともに、播種期と試験地を異にした場合の出穂期に対する内的要因の影響を解析し、純粋早晩性の適応的意義について検討した。春化後高（20℃）24時間日長条件下で栽培したときの止葉展開まで日数を純粋早晩性とする。世界各地のオオムギ1,017品種の純粋早晩性は12日から28日まで変異した。純粋早晩性の変異を地域別にみると、高緯度地域に分布する品種群は晩生であり、低緯度地域の品種群は早生であった。中緯度地域および極低緯度地域（エチオピア）の品種群では純粋早晩性の変異が大きく、この地域には高緯度地域よりも晩生の品種が多く存在した。重回帰分析の結果、倉敷における出穂期の早晩は秋播栽培条件では主として光周反応性によって支配されるが、春播栽培条件では主として純粋早晩性によって支配され、遅播きするほど純粋早晩性の影響が強いことが示された。春播栽培地域である北見においても出穂期は純粋早晩性の影響を強く受けていた。幼穂形成期における日長が十分に長い栽培条件では光周反応性は出穂期の調整要因として作用せず、純粋早晩性が出穂期を支配するものと考えられた。 kn-abstract=Heading time of is a complex character, which is controlled by several internal factors, namely, vernalization requirement, photoperiodic response and earliness in a narrow sense (ENS). The ecological significance of vernalization requirement and photoperiodic response has been clarified. However, the significance of ENS is not explained well. In this study, we examined the varietal variation of ENS, its geographical distribution and significance of ENS for regional adaptability in barley. The ENS was estimated from the number of days from sowing to flag-leaf emergence of sufficiently vernalized plants grown under a 24-h. photoperiod at 20℃ condition. The variation of ENS was determined from the number of leaves and leaf emergence intervals under the controlled condition. The ENS of 1,017 barley varieties ranged from 12 to 28 days. ENS was shortest in varieties from low-latitudes, while it was longer in varieties from high-latitudes and very low-latitudes. Multiple regression analysis for heading time(Y) on the ENS(X1) and the photoperiodic response(X2) was carried out using various data obtained from different experiment sites and sowing times. The multiple correlation was highly significant in all cases. It was clear that the ENS played an important role for determining heading time in the spring-sown conditions, while the photoperiodic response did in the fall-sown condition. en-copyright= kn-copyright= en-aut-name=OkuboKazuo en-aut-sei=Okubo en-aut-mei=Kazuo kn-aut-name=大久保和男 kn-aut-sei=大久保 kn-aut-mei=和男 aut-affil-num=1 ORCID= en-aut-name=YasudaShozo en-aut-sei=Yasuda en-aut-mei=Shozo kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=2 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Heading time kn-keyword=Heading time en-keyword=Geographica distribution kn-keyword=Geographica distribution en-keyword=Adaptability kn-keyword=Adaptability END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=3 article-no= start-page=167 end-page=178 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=197703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A linkage study of the two genes conditioning anthocyanin pigmentation in barley kn-title=オオムギのアントシアニン着色に関与する2遺伝子の連鎖研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HayashiJ. en-aut-sei=Hayashi en-aut-mei=J. kn-aut-name=林二郎 kn-aut-sei=林 kn-aut-mei=二郎 aut-affil-num=1 ORCID= en-aut-name=TakahashiR. en-aut-sei=Takahashi en-aut-mei=R. kn-aut-name=高橋隆平 kn-aut-sei=高橋 kn-aut-mei=隆平 aut-affil-num=2 ORCID= en-aut-name=MoriyaI. en-aut-sei=Moriya en-aut-mei=I. kn-aut-name=守屋勇 kn-aut-sei=守屋 kn-aut-mei=勇 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=1-2 article-no= start-page=72 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=195911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On the mildew resistance varieties in barley. kn-title=オオムギのウドンコ病に対する抵抗性品種について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HiuraU. en-aut-sei=Hiura en-aut-mei=U. kn-aut-name=日浦運治 kn-aut-sei=日浦 kn-aut-mei=運治 aut-affil-num=1 ORCID= en-aut-name=HetaH. en-aut-sei=Heta en-aut-mei=H. kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=48 cd-vols= no-issue=3 article-no= start-page=107 end-page=115 dt-received= dt-revised= dt-accepted= dt-pub-year=1961 dt-pub=196105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Pathogenic variability attributed to hybridization in Erysiphe graminis hordei.

The mutant was controlled by a recessive gene named frp 'fluorescent reaction-pink'. It was poor growth and was lethal. The transmissoin rate of the mutant gene was about 80% of that of the normal allele. Thus the segregation in the heterozygous populations was ca. 4 normal to 1 mutant. The frp gene is located close to gl-3, 'glossy leaf-3' on the 4H chromosome. en-copyright= kn-copyright= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=1 ORCID= en-aut-name=ChangCheng Lin en-aut-sei=Chang en-aut-mei=Cheng Lin kn-aut-name=張成林 kn-aut-sei=張 kn-aut-mei=成林 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Mutation kn-keyword=Mutation en-keyword=Fluorescence kn-keyword=Fluorescence en-keyword=Linkage analysis kn-keyword=Linkage analysis END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=3 article-no= start-page=139 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=198703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characters of Barley Resistance to Cereal Aphids (1) Occurrence and abundance of four cereal aphids on barley fields kn-title=オオムギの耐アブラムシ性要因 第1報 圃場における4種アブラムシの発生消長 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KawadaKazuo en-aut-sei=Kawada en-aut-mei=Kazuo kn-aut-name=河田和雄 kn-aut-sei=河田 kn-aut-mei=和雄 aut-affil-num=1 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=2 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=3 ORCID= en-aut-name=FukuokaMariko en-aut-sei=Fukuoka en-aut-mei=Mariko kn-aut-name=福岡まり子 kn-aut-sei=福岡 kn-aut-mei=まり子 aut-affil-num=4 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=3 article-no= start-page=149 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=198703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characters of Barley Resistance to Cereal Aphids (2) Nutritional differences with the barley strain kn-title=オオムギの耐アブラムシ性要因 第2報 系統間の栄養成分の差異 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=1 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=2 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=3 ORCID= en-aut-name=KawadaKazuo en-aut-sei=Kawada en-aut-mei=Kazuo kn-aut-name=河田和雄 kn-aut-sei=河田 kn-aut-mei=和雄 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=3 article-no= start-page=161 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=198703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Characters of Barley Resistance to Cereal Aphids (3) A surveying method for substances responsible for the resistance to aphids by artifical rearing kn-title=オオムギの耐アブラムシ性要因 第3報 人工飼育法による耐性物質の検索 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=1 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=2 ORCID= en-aut-name=ShiragaTakashi en-aut-sei=Shiraga en-aut-mei=Takashi kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=3 ORCID= en-aut-name=KawadaKazuo en-aut-sei=Kawada en-aut-mei=Kazuo kn-aut-name=河田和雄 kn-aut-sei=河田 kn-aut-mei=和雄 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=55 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Inheritance of Phenol Reaction in the Awn of Barley kn-title=オオムギの芒におけるフェノール着色反応の遺伝性 en-subtitle= kn-subtitle= en-abstract=オオムギの芒ではフェノールを酸化する酵素の活性が強くが、極めて少数の品種では芒のフェノール着色が見られない。本研究では芒のフェノール着色反応の遺伝性を解析した。結果は次の通り。1）芒のフェノール着色反応は優性遺伝子ph（phenol reaction）によって支配されている。2）Phは第2染色体にe-Ph-liの順で配列している。3）芒、穀皮および果実（果皮）の反応が一致しない場合があるが、これが実験誤差か、それぞれの組織で別個の遺伝子が作用していることによるのかは確認を要する。 kn-abstract=The inheritance and geographical distribution of the phenol reaction in rice has been investigated intensively. On the other hand, in the case of barley, almost all of the varieties show positive reaction to phenol, and inheritance study of the trait has not yet been reported. We investigated the phenol reaction of ca. 5,000 barley varieties preserved at the Barley Germplasm Center of Okayama University to find about 30 varieties which show a negative reaction to the phenol. These varieties are mainly from Southwest Asia. The reaction of awn was sharpest at all parts of the plant including seeds. The positive reaction must be the prototype of barley, because Hordeum spontaneum, a possible ancestor of the cultivated barley, shows positive reaction. Inheritance and linkage studies were conducted using varieties with negative reaction and linkage testers with positive reaction. Phenol reaction was dominant and showed a clear 3:1 segregation ratio in the F2 populations, indicating the trait was controlled by a single dominant gene Ph(phenol reaction). Linkage study revealed that Ph was linked with four marker genes(three loci) on the chromosome 2 and independent of 13 other marker genes located on the chromosomes except chromosome 2. Ph may be a useful marker gene and an interesting material for molecular-biological studies. en-copyright= kn-copyright= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=1 ORCID= en-aut-name=ZhangChan Lin en-aut-sei=Zhang en-aut-mei=Chan Lin kn-aut-name=張成林 kn-aut-sei=張 kn-aut-mei=成林 aut-affil-num=2 ORCID= en-aut-name=KanataniRyoichi en-aut-sei=Kanatani en-aut-mei=Ryoichi kn-aut-name=金谷良市 kn-aut-sei=金谷 kn-aut-mei=良市 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Phenol reaction kn-keyword=Phenol reaction en-keyword=Linkage analysis kn-keyword=Linkage analysis END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=63 end-page=68 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Genetic Analysis of Large Trichome in Barley Leaf Blade kn-title=オオムギの葉の剛毛に関する遺伝子分析 en-subtitle= kn-subtitle= en-abstract=岡山大学資源生物科学研究所大麦系統保存施設が保有するオオムギのうち約2,300品種を対象として、葉身の表面に生じる毛（trichome）の変異体を検索した。1）2,300品種のうち9品種（0.4％）が葉身の表面に剛毛を生じた。2）通常の品種では毛茸の鈎状部分の長さが約10μmであるのに対して剛毛型の品種では約40μmであった。Pub遺伝子による長毛はこれよりはるかに長く、剛毛型とは明らかに異なった。3）剛毛型は優性の1遺伝子（Ltr,large trichome）に支配されており、連鎖分析の結果、第7染色体にLtr-s-fsの順に配列されることが明らかになった。 kn-abstract=The inheritance and linkage relationship of a new hairiness trait "large trichome" was investigated in barley. Although the size of large trichome is about four times that of normal one, the character can not be recognized with the naked eye. However, it is easily identified by the roughness of leaf touch. The large trichomes develop on both sides of the leaf blades. The direction of trichome is both acropetal and basipetal. It is clearly distinguished from the extremely long trichome controlled by Pub gene. About 2,300 varieties of our Barley Germplasm Center were screened by the leaf touch to find nine varieties with large trichome. Two of them were six-rowed local variety from Pakistan, and other seven were two-rowed varieties from Europe and Japan. All of them were hulled type. Crosses of six large trichome varieties with a normal Japanese variety resulted in the large trichome type F1s, suggesting the dominant nature of the trait. The large trichome line Hokuiku 17 was crossed with various linkage testres to study the mode of inheritance and the linkage relationship of the gene. In the F2 populations, the large trichome was controlled by a single dominant gene named Ltr (large trichome), which was independentiy inherited from the following marker genes; br and gl-5 on chromosome 1; li and ν on chromosome 2; uz on chromosome 3; K and gl-3 on chromosome 4; trd on chromosome 5; ο on chromosome 6. On the other hand, from the cross between Hokuiku 17 and OUL166, Ltr was found to be linked with s and fs on chromosome 7. Although the allelism test has not been completed, the very low frequency of the large trichome type (9/2,300) indicates that the variant resulted from a recent mutation event, or the fitness of the variant is low in the natural and/or artificial selection. en-copyright= kn-copyright= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name=佐藤和広 kn-aut-sei=佐藤 kn-aut-mei=和広 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Trichome kn-keyword=Trichome en-keyword=Linkage analysis kn-keyword=Linkage analysis END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=55 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Comparison between shoot Regeneration Ability in Calli Derived from Immature Embryos of Wild and Cultivated Barley kn-title=オオムギの近辺野生種と栽培種における未熟胚由来カルスからの再分化能の比較 en-subtitle= kn-subtitle= en-abstract=本研究ではオオムギ近緑野生種Hordeum spontaneum82系統とH.agriocrithon13系統、計2種95系統および世界各地の栽培種87品種を供試して、未熟胚由来カルスからの不定芽再分化能を調査し、近緑野生種と栽培種における再分化能の品種変更およびその地理的分化を比較した。近緑野生種では95系統中94系統がカルスを形成し、そのうち85系統（90.4％）が不定芽を再分化して、不定芽再分化率は系統によって1.2％から75.7％まで幅広く変異した。カルスを形成した94系統における不定芽再分化率の平均値は21.7％、緑色不定芽再分化率は11.5％、アルビノ不定芽再分化率は10.2％であった。H.spontaneumとH.agriocrithonの不定芽再分化率の平均値はそれぞれ21.4％と23.9％で、有意差は認められなかった。しかし、H.spontaneumに含まれる6品種（dawense, ishnatherum, laguncliforme, paradoxon, proskowetzii, spontaneum）の間では不定芽再分化率に差異が認められた。栽培種では供試品種のすべてがカルスを形成し、そのうち73品種（83.7％）が不定芽を再分化して、不定芽再分化率は品種によって3.2％から85.5％まで幅広く変異した。供試品種全体の不定芽再分化率の平均値は25.4％、緑色不定芽再分化率は22.0％、アルビノ不定芽再分化率は3.4％であった。このように、不定芽再分化率に対する緑色不定芽再分化率の占める割合は栽培種で86.6％、近緑野生種で53.0％となり、両者に大きな差が認められた。供試した栽培種を小穂非脱落性に関する遺伝子型によって東亜地域に多く分布するBt bt2型と西域に多く分布するbt Bt2型に分けて不定芽再分化率を比較すると、Bt bt2型の平均値は16.2％、bt Bt2型の平均値は32.3％となり、bt Bt2型の不定芽再分化率が有意に高く、地理的分化が認められた。しかし、近緑野生種では不定芽再分化能の地域間差がみられないので、オオムギの祖先種が栽培化されてから不定芽再分化能の地理的分化が生じたものと考えられる。 kn-abstract=The variation in shoot regeneration obility of calli derived from immature embryos was examined in 95 wild strains, 82 of which were of Hordeum spontaneum and 13 of which were H. agriocrithon, and 87 cultivated varieties collected from various countries or regions of the world. In 85 strains of the wild species, a number of calli regenerated shoots, and their proportion ranged from 1.2% to 75.7%. The average percentage of shoot regenerating calli was 21.7% among the strains that formed calli, 11.5% of which regenerated green and 10.2% albino shoots. On average, 21.4% and 23.9% calli regenerated shoots in H. spontaneum and H. agriocrithon, respectively and there was no significant difference between these values. A significant difference in the percentage of shoot regenerating calli was found among six variants (dawense, ishnatherum, laguncliforme, paradoxon, proskowetzii, spontaneum) which were comprised in H. spontaneum. In 73 varieties of cultivated species, there were shoots regenerating calli likely to wild species, and their proportion ranged from 3.2% to 85.5%. The average percentage of shoot regenerating calli was 25.4%, 22.0% of which regenerated green and 3.4% of which regenerated albino shoots. There was a significant difference in percentage of green shoots regenerating calli against shoots regenerating ones between the wild (53.0%) and cultivated species 886.6%). The two kinds of non-brittle rachis genotypes, Bt bt2 and bt Bt2 are one of the key characters distinguishing the oriental and occidental types of cultivated barley. The average percentages of shoot regenerating calli were 16.2% and 32.3% for the genotypes Bt bt2 and bt Bt2, respectively, suggesting that there is a geographical variation in the shoot regeneration ability of calli in the cultivated species. By contrast, the oriental and occidental strains of wild species showed no difference in the shoot regeneration ability of calli. The geographical variation of shoot regeneration ability differed significantly between wild and cultivated species. This suggests that the geographical variation of shoot regeneration ability occurred after the cultivation of the barley was established. en-copyright= kn-copyright= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name=力石和英 kn-aut-sei=力石 kn-aut-mei=和英 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= en-aut-name=YasudaShozo en-aut-sei=Yasuda en-aut-mei=Shozo kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Hordeum spontaneum kn-keyword=Hordeum spontaneum en-keyword=Hordeum agriocrithon kn-keyword=Hordeum agriocrithon en-keyword=Tissue culture kn-keyword=Tissue culture en-keyword=Geographical variation kn-keyword=Geographical variation en-keyword=Shoot regeneration ability kn-keyword=Shoot regeneration ability END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=111 end-page=122 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Comparison of Resistance to Powdery Mildew between Wild Barley (Hordeum spontaneum C.

Koch originating from Iran, Iraq, Turkey and Central Asia, were tested for resistance to powdery mildew. Then, the variation of resistance was compared with that of 145 local varieties of cultivated barley (Hordeum vulgare L.) originating from the same region of the wild barley collection. Ten different isolates of the parasite with Japanese origin were separately inoculated onto the first leaves of the host plants. The infection types were classified into the following: i, immunelike; R, highly resistant; M, moderately resistant; and S, highly susceptible. Resistant strains with i, R or M infection type were more frequent among wild barleys as compared with the cultivated forms. It is noteworthy that among these three resistant reactions,the M type was most frequent in the wild barley. To compare the degree of resistance to a total of 10 isolates, the resistance score was calculated in each of the wild and cultivated strains as the following: Scores 1,2,3 and 4 were given to the infection types of i, R, M and S, respectively, and the mean score for 10 isolates was calculated. Wild barley showed significantly low resistance scores as compared with those of cultivated barley. This was also confirmed by the cluster analysis; the cluster with more resistance to 10 isolates consisted of many strains of wild barley. Next, the resistance of wild barley was characterized by their broader effective ranges to different isolates. According to the x2 test for independence of reactions to two different isolates, the resistant factor(s) involved in wild barley was confirmed to be rather non-specific to the parasite. It was concluded that H. spontaneum may be useful genetic resources for the breeding of resistance to powdery mildew as well as local varieties. en-copyright= kn-copyright= en-aut-name=FukuyamaToshinori en-aut-sei=Fukuyama en-aut-mei=Toshinori kn-aut-name=福山利範 kn-aut-sei=福山 kn-aut-mei=利範 aut-affil-num=1 ORCID= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=2 ORCID= en-aut-name=SatoKazuhiro en-aut-sei=Sato en-aut-mei=Kazuhiro kn-aut-name=佐藤和広 kn-aut-sei=佐藤 kn-aut-mei=和広 aut-affil-num=3 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Hordeum spontaneum kn-keyword=Hordeum spontaneum en-keyword=Barley kn-keyword=Barley en-keyword=Powdery mildew kn-keyword=Powdery mildew en-keyword=Resistance kn-keyword=Resistance END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=7 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Heterosis in Barley Cultivars kn-title=オオムギの雑種強勢に関する研究 en-subtitle= kn-subtitle= en-abstract=自殖性作物のオオムギでは、小穂脱落をはじめ補足遺伝子によって発現する多くの障害が知られている。このような障害の生じない交雑組合せでF1にどの程度のヘテローシスが現れるか、ヘテローシスの発現と品種分布の地域性との関係があるかどうかについて試験を行った。そのため日本の数品種を共通親とし、世界各地の品種との交雑を行った。結果の大要は以下の如くである。1.六条品種（並性）の交雑では、日本、中国及び朝鮮半島の43品種に、日本の六条皮及び裸麦をそれぞれ交雑し、ヘテローシスの程度を調べた。その結果個体当り収量に最も高いヘテローシスを示したのは朝鮮半島の品種で、F1/MPの交雑平均値1.37、最大のヘテローシスを示した組合せはF1/BPが1.45であった。2.二条品種の場合は、世界各地からの78品種の共通親として日本の2品種を交雑したF1156を調査した。トルコやエチオピアの品種との交雑でヘテローシスが高く、個体当り収量に対するヘテローシスの最大値を示した組合せは、F1/BPがそれぞれ1.66と1.45であった。3.日本特有の半矮性品種の場合は34品種を用い、これらに皮及び裸性の渦性2品種を共通親としたF1を調査した。これらの交雑でもヘテローシスが発現し、皮麦×裸麦のF1でヘテローシスが高かった。4.世界各地の二条品種10用いた片面ダイアレル分析の結果、一般組合せ能力の高い品種（エチオピア）や特定組合せ能力の高い品種（フランス）が見いだされた。5.二条オオムギで収量への寄与が最も大きかった形質は、一株穂数であったが、降雨の多い年次に行った試験結果では1000粒重の影響が大であった。これは、過繁茂による登熟歩合の低下が主因と考えられたが、品種により過繁茂でも登熟歩合がほとんど低下しない組合せがあった。 kn-abstract=In cultivated barley, various hybrid injuries such as brittle rachis and hybrid weakness occur. Therefore, crossing must be done among cultivars to prevent the occurrence of such hybrid injuries. In the present study, we examined the magnitude of the heterosis in the crossings and geographical distribution of barley cultivars concerning heterosis. A few Japanese cultivars were used as the common parent for crossing. (1) In the six-rowed barley, 43 cultivars collected from Japan, China and Korea were crossed with non-uzu covered and naked cultivars, Shiroyo-shigara 2 and Nami-Akashinriki, respectively. The largest magnitude of heterosis in grain yield per plant was obtained in the crossing between the Korean cultivar and one of the Japanese common parents. (2) Heterosis in two-rowed cultivars was investigated using a total of 156 F1S which were cross combinations of cultivars collected from the world with two common male parents, Amagi Nijo and Kawasaigoku. The heterosis was larger larger in the cross combinations with Turkish and Ethiopian cultivars. The largest F1/BP was 1.66 in Turkish and 1.45 in Ethiopian cultivars. (3)　As to uzu or semi-dwarf cultivars peculiar to Japan, 34 cultivars were crossed with two common male parents, Sekitori (covered) and Akashinriki (naked). Expression of the heterosis was rather conspicuous in the crosses of covered×naked cultivars than those of covered×covered and naked×naked ones. (4) Half diallel analysis using 10 two-rowed cultivars showed that one Ethiopian cultivar expressed a high grade of general combining ability and that one French cultivar was of higher specific combining ability. (5) The most effective agronomic character of the two-rowed cultivars to the grain yield per piant was number of ears in an ordinary year, while in the wet year it was 1000 grain weight. This was considered to be due to overluxuriant growth accompanied by lowering of the percentage of ripened grain.

These materials were taken from a world-wide collection preserved at the Barley Germplasm Center of Okayama University. The callus forming ability varied widely according to genotype in both mature and immature embryos, but the varieties collected from Ethiopia showed low callus forming ability. Calli derived from mature embryos generally did not regenerate shoots, except for three Japanese varieties. The frequency of shoot regeneration from the calli derived from immature embryos was somewhat higher than that from those derived from mature embryos. Many of the Korean and Japanese varieties had a high shoot regenerating ability. However, few of the varieties from Ethiopia and Southwest Asia had a high shoot regenerating ability. No correlation was observed btween root regenerating ability and shoot regenerating ability of the varieties. No correlation was observed between callus proliferation and root regenerating ability between calli derived from mature and immature embryos. We could not find any difference in the shoot regenerating ability btween the two-rowed and six-rowed genotypes. en-copyright= kn-copyright= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name=力石和英 kn-aut-sei=力石 kn-aut-mei=和英 aut-affil-num=1 ORCID= en-aut-name=YasudaShozo en-aut-sei=Yasuda en-aut-mei=Shozo kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Tissue culture kn-keyword=Tissue culture en-keyword=Mature embryo kn-keyword=Mature embryo en-keyword=Immature embryo kn-keyword=Immature embryo en-keyword=Regenerating kn-keyword=Regenerating END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=4 article-no= start-page=173 end-page=183 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=197303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=オオムギ品種における穂揃い性の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=沖永康男 kn-aut-sei=沖永 kn-aut-mei=康男 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=71 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=1995 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Varietal Variation and Effects of Some Major Genes on Salt Tolerance in Barley Seedlins kn-title=オオムギ幼植物の耐塩性における品種変異と各種主働遺伝子の効果 en-subtitle= kn-subtitle= en-abstract=本研究では耐塩性品種を見出す目的で、世界各地のオオムギ5,182品種について幼植物の耐塩性の品種変異ならびにその地理的変異、および主要形質との関係を調査した。幼植物の耐塩性を地域別に比較すると、朝鮮半島および日本の品種が強く、ネパールと西南アジアの品種が弱い傾向にあった。次に、条性や皮裸性など、オオムギにおける主要形質と幼植物の耐塩性との関係を調べるために、5,182品種を主要形質に分けて耐塩性を比較した結果、六条品種は二条品種より、皮品種は裸品種より、小穂非脱落性のE型はW型より、日本と朝鮮半島に分布する六条の渦品種は、同地域の六条の並品種よりもそれぞれ耐塩性が有意に強かった。さらに、供試品種を条性、皮裸性および小穂非脱落性の3形質の組合せで8タイプに分類して幼植物耐塩性を比較したところ、皮裸性、小穂非脱落性が同じ場合、二条品種と六条品種の間では有意差がなく、また、皮裸性と小穂非脱落性の組合せによって耐塩性の強弱が逆転した。同質遺伝子系統を用いて幼植物の耐塩性を比較したところ、品種群でみられた条性、皮裸性の間における耐塩性の差異は、品種群の遺伝的背景の差異によるものとみられた、一方、並渦性でみられた耐塩性の差異は主働遺伝子の副次的効果によるものとみられた。 kn-abstract=In order to select the salt tolerant cultivars, and to evaluate the effects of some major genes on salt tolerance in barley, 5,182 varieties and 368 isogenic lines were tested by exposing to 1.0 and 0.5M sodium chloride at the seedling stage. The average rating of salt tolerance was higher in varieties from Korea and Japan , but lower in varieties from Nepal and Southwest Asia. When the varieties were grouped by several morphological characters, six-rowed, covered, E type of nonbrittle rachis and uzu type groups were more tolerant than two-rowed, naked, W type and non-uzu type counterparts, respectively. A comparison between the isogenic pairs revealed that the uzu type was more tolerant than non-uzu type, but other major gene pairs did not show any obvious differences. These findings indicate that the uz gene affects the salt tolerance, and diferences between varietal groups characterized by other major genes are due to the difference in the genetic background among these varieties. en-copyright= kn-copyright= en-aut-name=ManoYoshiro en-aut-sei=Mano en-aut-mei=Yoshiro kn-aut-name=間野吉郎 kn-aut-sei=間野 kn-aut-mei=吉郎 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Seedling kn-keyword=Seedling en-keyword=Salt tolerance kn-keyword=Salt tolerance en-keyword=Screening kn-keyword=Screening en-keyword=Isogenic line kn-keyword=Isogenic line END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=43 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Genetical Studies on Callus Growth and Plant Regeneration from Immature Embryos in Barley kn-title=オオムギ未熟胚培養系におけるカルス生長量及び植物体再分化能の遺伝解析 en-subtitle= kn-subtitle= en-abstract=オオムギ培養細胞の再分化の制御や細胞選抜の実用化に寄与するために、植物体再分化能の遺伝様式を解析した。未熟胚培養系においては世界各地の99品種についてカルス生長量及び植物体再分化能の調査を行ったところ、両形質共に連続的な変異を示し、複数の遺伝子あるいは微動遺伝子が関与していることが推察された。カルス生長量及び植物体再分化能の遺伝様式を調べるために、6品種で正逆総当たり交雑を行い、ダイアレル分析を行った。カルス生長量については、非対立遺伝子間の相互作用（エピスタシス）があると推察された。一方、植物体再分化能については、特定組み合わせ能力が高かったP1（J232）を除いた副ダイアレルの分析によって、植物体再分化能の遺伝変異は主として遺伝子の相加効果によるものと推察され、その平均優性度は0.42であった。遺伝率の推定値は狭義で0.78、広義で0.86といずれも高かった。 kn-abstract=Immature embryos of 99 varieties of barley were cultured to investigate the ability of callus growth and plant regeneration. These two in vitro traits showed wide and continuous variations among the barley varieties tested. Ability of callus growth, which were evaluated by callus diameter ranged from 3.9mm to 11.2mm, and ability of plant regeneration from the calli ranged from 0% to 100%. A set of complete diallel crosses was made using six cultivars as the parents which differed in ability of callus growth and plant regeneration. The Vr/Wr graphical analysis showed that there were epistasis, or interaction among nonallelic genes for callus growth. As to ability of plant regeneration, no epistasis existed in the subdiallel without P1 (J232) which showed high specific combining ability, and it was controlled by a simple additive dominance genetic system. The mean degree of dominance(0.42) was relatively low and the broad(0.86) and narrow(0.78) sense heritabilities were high. en-copyright= kn-copyright= en-aut-name=ManoYoshiro en-aut-sei=Mano en-aut-mei=Yoshiro kn-aut-name=間野吉郎 kn-aut-sei=間野 kn-aut-mei=吉郎 aut-affil-num=1 ORCID= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name=力石和英 kn-aut-sei=力石 kn-aut-mei=和英 aut-affil-num=2 ORCID= en-aut-name=YasudaShozo en-aut-sei=Yasuda en-aut-mei=Shozo kn-aut-name=安田昭三 kn-aut-sei=安田 kn-aut-mei=昭三 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Barley kn-keyword=Barley en-keyword=Tissue culture kn-keyword=Tissue culture en-keyword=Plant regeneration kn-keyword=Plant regeneration en-keyword=Diallel analysis kn-keyword=Diallel analysis END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=21 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=1999 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=QTL Mapping for Water Sensitivity in Barley Seeds kn-title=オオムギ種子感水性のＱＴＬマッピング en-subtitle= kn-subtitle= en-abstract=Steptoe×Morex（S/M)およびHarrington×TR306（H/T)の倍加半数体（DH)系統を用いて種子の感水性のQTL解析を行った。DH系統は連続的な超越分離を示し、S/Mでは3個、H/Tでは1個の有意なQTLが見出され、それぞれ感水性の変異の約1/4が説明された。これらのQTLの近傍には発芽速度などの発芽に関する他のQTLが見出された。 kn-abstract=Sensitivity to water condition during germination is an important character in malting barley because it affects malt poduction. Water sensitivity in malting barley is defined as the defference in germination percentage between the seeds in standard and excess-water conditions. Usually standard and excess-water condition means 4 and 8 ml water in a 90 mm perti dish, respectively. Takeda and Fukuyama (1983) examined more than 4,000 barley accessions and found 0〜100% water sensitivity. This means complete to no suppression of germination by an excess-water condition. In this study, quantiative trait loci (QTL) analysis was applied to analize the inheritance of water sensitivity. Two sets of doubled haploid (DH) populations derived from Steptoe×Morex (S/M) and Harrington×TR306 (H/T) crosses,were grown in the experiment field of the Research Institute for Bioresources, Okayama University. Bulbosum method was adapted to develop DH lines (Chen and Hayes 1989). Water sensitivities of 150 (S/M) and (H/T) lines and their parents were evaluated using 50 seeds each and the germination test (25℃, 4 days) was repeated four times. Water sensitivity showed a large variation (Fig.1) and the heritability of the trait was 0.78 and 0.72 in S/M and H/T, respectively, indicating that about three-quarters of the phenotypic variance was genetic in origin. Three (S/M) and one (H/T) significant QTL were detected and 23% (S/M) and 25% (H/T) of the phenotypic variance was explained by the QTL. These QTL were located on chromosomes 2H,3H,6H and 7H (Table 1, Fig. 2). QTL relating to germination traits were lacated near the QTL controlling water sensitivity (Fig. 3).　Interaction among the QTL was small (Table 2). Marker-assisted selection was effective (Table 3). en-copyright= kn-copyright= en-aut-name=IwasaTomohiko en-aut-sei=Iwasa en-aut-mei=Tomohiko kn-aut-name=岩佐友彦 kn-aut-sei=岩佐 kn-aut-mei=友彦 aut-affil-num=1 ORCID= en-aut-name=TakahashiHidekazu en-aut-sei=Takahashi en-aut-mei=Hidekazu kn-aut-name=高橋秀和 kn-aut-sei=高橋 kn-aut-mei=秀和 aut-affil-num=2 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=barley kn-keyword=barley en-keyword=water sensitivity kn-keyword=water sensitivity en-keyword=QTL analysis kn-keyword=QTL analysis END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=2 article-no= start-page=139 end-page=149 dt-received= dt-revised= dt-accepted= dt-pub-year=1990 dt-pub=199003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Mechanical Transmission of Barley Yellow Mosaic Virus and Diagnosis of the Virus kn-title=オオムギ縞萎縮病の汁液接種検定並びに診断 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=2 ORCID= en-aut-name=MitsuhataKōji en-aut-sei=Mitsuhata en-aut-mei=Kōji kn-aut-name=光畑興二 kn-aut-sei=光畑 kn-aut-mei=興二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=9 end-page=23 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=1996 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Secretion of Defensive Substance by Carabidae and Brachinidae kn-title=オサムシ科とクビボソゴミムシ科の防御物質の分泌 en-subtitle= kn-subtitle= en-abstract=オサムシ科とクビボソゴミムシ科の防御物質の分泌について系統分類学の視点から250種以上を調べた。属レベル共通性が見られたが、中には亜属や種での特異性のある成分が検出された。防御物質の分泌に関する器官は左右一対の多数の小型の生合成器官、大きな貯蔵?、それをつなぐ輸送管と末端環節間膜に開孔する分泌管より構成されていた。体の大小、管の嵌入場所や貯蔵?の形などで、種による特徴があったが、生合成器官の形に相応して生成物質に特徴があった。すなわち、球形器官は短鎖有機酸を、紐状器官はメタクレゾールを、板状器官はベンゾキノンを生成した。有紀酸の分泌種としてはギ酸分泌種があり、この類にあっては副成分として2トリデカノンを含む類とエステルを含む類があった。オサムシ族、ナガゴミムシ族その他かなり多くの種類は分岐アミノ酸であるバリン、イソロイシンとロイシンやリジンから生成されるメタアクリル酸、チグリン酸、エチルアクリル酸、セネシオ酸やクロトン酸と各々の飽和酸の幾つかを構成成分としていた。一般的に属レベルで同じ成分が多かったが、例外的に種の特異性成分もあった。メタクレゾールはキベリアオゴミムシ亜属を例外とするアオゴミムシ類とヨツボシゴミムシ類で検出された。ベンゾキノン類はキベリアオゴミムシ亜属が分泌し、亜属で特徴を示した。この類は貯蔵?のみからの体温での分泌であった。クビボソゴミムシ科もキベリアオゴミムシ類と同じ組成のベンゾキノンを分泌するが、貯蔵?に接して茶褐色をした酸化反応室を有し約100℃の高温噴射を爆発音と共に行った。 kn-abstract=The secretion of defensive substances by more than 250 species of carabid and brachinid beetles was investigated, and discussed from a phylogenetical viewpoint. The morphological of secretion glands and secreted components were identified in the genus level. Specific subgenus and species had peculiar characteristics. The pair of defensive organs consisted of many small synthetic lobes, large reservoirs, collecting ducts from lobes to reservoirs and secretion ducts from reservoirs. The pair dust opened at the last sternal intersegmental membrane. There was species specificity in the reservoir shape, synthetic lobe shape and entering site of the collecting ducts into reservoirs. The spherical shape lobes produced short chain fatty acids, the elongated shape lobes produced m-cresol and the thick board shape lobes produced benzoquinones. Two types of fatty acid-secreting beetles were found, one secreted formic acid, and the other mixed short chain fatty acids. These short chain fatty acids were metabolized from some amino acids, methacrylic acid was from valine; tiglic acid, α-ethyacrylic acid and angelic acid were from isoleucine; senecioic acid was from leucine and crotonic acid was from lysine. These unasaturated acids were sometimes detected with a trace amount of corresponding saturated acids. A few species secreted larger amounts of saturated acids with a trace amounts of unsaturated acids. Fatty acid composition was generally genus-specific. In a few cases, however, species-specific acid composition was also observed. m-Cresol-secreting beetles were observed only in Panagaeni and Chlaeniini except subgenus Chlaenius Chlaeniini except subgenus Chlaenius Chlaeniellus beetle. 1,4-Benzoquinone and 2-methyl-1,4-benzoquinone-secreting beetles were observed in subgenus C. Chlaeniellus. This beetle secreted these substances at body temperature from a reservoir with no sound. Brachinidae beetles, called bombardier beetles, have a pair of brownish reaction chamber connected with a reservoir. They sprayed the two benzoquinones at about 100℃ making sound. en-copyright= kn-copyright= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=Defensive secreting substance kn-keyword=Defensive secreting substance en-keyword=Synthetic organ kn-keyword=Synthetic organ en-keyword=Carabidae kn-keyword=Carabidae en-keyword=Brachinidae kn-keyword=Brachinidae en-keyword=Phylogenetic relation kn-keyword=Phylogenetic relation END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=2 article-no= start-page=93 end-page=100 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Comparative study of the pygidial defensive systems of adults of Carabidae (Coleoptera) kn-title=オサムシ類成虫の尾部防御分泌系の比較 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KanehisaK. en-aut-sei=Kanehisa en-aut-mei=K. kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=1 ORCID= en-aut-name=YamashitaT. en-aut-sei=Yamashita en-aut-mei=T. kn-aut-name=山下俊和 kn-aut-sei=山下 kn-aut-mei=俊和 aut-affil-num=2 ORCID= en-aut-name=ShiragaT. en-aut-sei=Shiraga en-aut-mei=T. kn-aut-name=白神孝 kn-aut-sei=白神 kn-aut-mei=孝 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=1 article-no= start-page=47 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680329 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Oviposition and egg adhesive substances of tent caterpillar, Malacosoma neustria L.(Lepidopiera: Lasiocampidae). kn-title=オビカレハMalacosoma neustria L.

Female could make a gall and oviposit at 20℃, but only make a gall at 15℃. Although it could neither make a gall nor oviposit at 25℃, it oviposited at than temperature when placed on a gall. Female neither made a gall nor oviposited on an extended young leat. However, it could oviposit on the young leaf rolled artificially in a line tube (3.2 mm diam.), but not on the old one. These findings show that univoltine of the thrips may be regulated by the phenology of the host plant and females can oviposit whenever they are placed on the seedlings at the optimum oviposition temperature. en-copyright= kn-copyright= en-aut-name=UchiyamaKeiji en-aut-sei=Uchiyama en-aut-mei=Keiji kn-aut-name=内山圭二 kn-aut-sei=内山 kn-aut-mei=圭二 aut-affil-num=1 ORCID= en-aut-name=KawadaKazuo en-aut-sei=Kawada en-aut-mei=Kazuo kn-aut-name=河田和雄 kn-aut-sei=河田 kn-aut-mei=和雄 aut-affil-num=2 ORCID= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=3 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Oviposition factor kn-keyword=Oviposition factor en-keyword=Thrips kn-keyword=Thrips en-keyword=Ponticulothrips diospyrosi kn-keyword=Ponticulothrips diospyrosi en-keyword=Gall kn-keyword=Gall en-keyword=Persimmon kn-keyword=Persimmon END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=3 article-no= start-page=141 end-page=148 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Variations of calcium, phosphorus, magnesium, and cadmium contents in anomalous-vertebrae fish induced by cadmium kn-title=カドミウムによって誘発された脊椎骨異常魚のカルシウム, 燐, マグネシウムおよびカドミウム含有量の変化 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MuramotoS. en-aut-sei=Muramoto en-aut-mei=S. kn-aut-name=村本茂樹 kn-aut-sei=村本 kn-aut-mei=茂樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=1 article-no= start-page=13 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=1979 dt-pub=197903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the odour components of stink and squash bugs kn-title=カメムシ類の悪臭成分に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YamashitaT. en-aut-sei=Yamashita en-aut-mei=T. kn-aut-name=山下俊和 kn-aut-sei=山下 kn-aut-mei=俊和 aut-affil-num=1 ORCID= en-aut-name=KanehisaK. en-aut-sei=Kanehisa en-aut-mei=K. kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=2 article-no= start-page=55 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the viruses of plants in Compositae in Japan I.

White Burley and the symptoms were observed up to three months after inoculation. These isolates were divided into four goups accoding to symptomatology on tabacco plant. None of the isoletes obtained from lilies infected tobacco plants systemically. The plants inoculated with isolates of the P serotype showed systemic mosaic, but only occasional mild symptoms were observed on newly developed leaves. On the other hand, all isolates of Y serotype showed symptoms consisting of mosaic, distortion and/or necrosis throughout the experimental period. In another experiment, reactions of some selected test plants to 30 isolates belonging to the Y or P serotype were examined. Lily isolates may be unique strain of CMV as they did not cause systemic infections on Lycopersicon esculentum, Solanum melongena or Cucumis sativus. Host range tests using 16 isolates originally obtained from plants other than lilies demonstrated a close relationship between serotype and pathogenicity to some test plants including N.tabacum, N. clevelandii, L.esculentum, Pisum sativum, phaseolus angularis and Zea mays. en-copyright= kn-copyright= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=1 ORCID= en-aut-name=MitsuhataKoji en-aut-sei=Mitsuhata en-aut-mei=Koji kn-aut-name=光畑興二 kn-aut-sei=光畑 kn-aut-mei=興二 aut-affil-num=2 ORCID= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Cucumber mosaic virus kn-keyword=Cucumber mosaic virus en-keyword=Serotype kn-keyword=Serotype en-keyword=Pathogenicity kn-keyword=Pathogenicity END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=4 article-no= start-page=175 end-page=186 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=196703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on cumber green mottle mosaic virus in Japan.

Rubidium absorption in Chlorella was clearly stimulated by the irradiation of light. To clarify the mechanism of light-stimulation on rubidium absorption, experiments were carried out using several metabolic inhibitors; DCMU, NaCN,DNP,CCCP and ouabain. Among the metabolic inhibitors used, DCMU had the most similar effects on the rubidium absorption and oxygen evolution under light condition. These findings suggest a close correlation between the light-stimulation on rubidium absorption and the photosynthetic process in Chlorella. en-copyright= kn-copyright= en-aut-name=HachiyaKinji en-aut-sei=Hachiya en-aut-mei=Kinji kn-aut-name=蜂谷欽司 kn-aut-sei=蜂谷 kn-aut-mei=欽司 aut-affil-num=1 ORCID= en-aut-name=MoritsuguMasumi en-aut-sei=Moritsugu en-aut-mei=Masumi kn-aut-name=森次益三 kn-aut-sei=森次 kn-aut-mei=益三 aut-affil-num=2 ORCID= en-aut-name=KawasakiToshio en-aut-sei=Kawasaki en-aut-mei=Toshio kn-aut-name=河ｱ利夫 kn-aut-sei=河ｱ kn-aut-mei=利夫 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Chlorella kn-keyword=Chlorella en-keyword=Light-stimulation kn-keyword=Light-stimulation en-keyword=Metabolic inhibitors kn-keyword=Metabolic inhibitors en-keyword=Oxygen evolution kn-keyword=Oxygen evolution en-keyword=Rubidium absorption kn-keyword=Rubidium absorption END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1-2 article-no= start-page=25 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=1969 dt-pub=196903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=クロレラの培養ならびに無機養分要求性について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=河崎利夫 kn-aut-sei=河崎 kn-aut-mei=利夫 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=堀士郎 kn-aut-sei=堀 kn-aut-mei=士郎 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=鬼頭俊而 kn-aut-sei=鬼頭 kn-aut-mei=俊而 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=森次益三 kn-aut-sei=森次 kn-aut-mei=益三 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue=2 article-no= start-page=107 end-page=111 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Factors on the termination of adult diapause and reproductive development in Gastrophysa atrocyanea Mot.

The corssing and selection process were repeated five times with the progenies. Isolates of each generation were inoculated on the non-hosts, Hordeum vulgare and Agropyron tsukushiense var. transiens OHWI, and parasitism and pathogenicity were investigated with respect to host specificity.As shown in Tables 2 to 5, the process of crossing and selection produced isolates which were pathogenic on barley cultivars, 'Kagoshimahadaka' or 'Russian 9' or Agropyron tsukushiense ecotypes 'Agropyron Early ecotype' or 'Agropyron Yezoense 3'.Factors affecting the degree of pathogenicity appear to be under polygenic control. The cumulative effect of minor genes may play a role in the differentiation of formae speciales suggesting a new concept of pathogenicity in the powdery mildew of grasses. en-copyright= kn-copyright= en-aut-name=HetaHideo en-aut-sei=Heta en-aut-mei=Hideo kn-aut-name=部田英雄 kn-aut-sei=部田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Wheat powdery mildew kn-keyword=Wheat powdery mildew en-keyword=Host specific kn-keyword=Host specific en-keyword=Pathogenicity kn-keyword=Pathogenicity en-keyword=Properties kn-keyword=Properties en-keyword=Barley kn-keyword=Barley en-keyword=Agropyron kn-keyword=Agropyron END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=61 end-page=68 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=1997 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Phenol Reaction of Kernels and Chromosome Location of Phenol Reaction Genes in the Genus Triticum kn-title=コムギ属植物における穀粒のフェノール反応の変異およびフェノール反応に関与する遺伝子の座乗染色体 en-subtitle= kn-subtitle= en-abstract=1. コムギ属における穀粒のフェノールによる着色反応を調査した結果、二粒系コムギでは着色する系統としない系統が存在するが、普通系コムギでは3,200以上の品種を供試したにもかかわらず、穀粒がフェノールによって着色しない系統は見いだされなかった。合成コムギ（AABBDD）にはフェノールによって着色しない系統が見出された。2.　異数体分析によって普通系コムギの穀粒のフェノール反応を支配する遺伝子が2Aと2D染色体に座乗することが明らかになり、2B染色体にも穀粒のフェノール反応を支配する遺伝子の存在が認められ、コムギの第2同祖群の全ての染色体にフェノール反応遺伝子が存在することが確かめられた。3.　フェノール反応遺伝子と無葉耳遺伝子が見出されているイネ科植物の染色体の同祖性について考察した。 kn-abstract=A total of 3,606 accessions of the genus Triticum involving diploid, tetraploid, hexaploid, and synthetic wheat and 7 Aegilops materials were tested for the phenol reaction in kernels. All hexaploid wheat showed a positive reaction to phenol, but deffered in staining degree. One of the synthetic wheat lines showed a negative reaction to phenol. Using monosomics, ditelosomics and nulli-tetrasomics in the common wheat cv Chinese Spring (Triticum aestivum L.), and Langdon (Triticum turgidum var. durum) disomic substitutions, genes controlling phenol reaction of kernels were located on chromosomes 2A, 2B and 2D. Synteny of the chromosome region involving the phenol reaction gene in some gramineous plants was discussed. en-copyright= kn-copyright= en-aut-name=ChangCheng Lin en-aut-sei=Chang en-aut-mei=Cheng Lin kn-aut-name=張成林 kn-aut-sei=張 kn-aut-mei=成林 aut-affil-num=1 ORCID= en-aut-name=TakedaShin en-aut-sei=Takeda en-aut-mei=Shin kn-aut-name=武田真 kn-aut-sei=武田 kn-aut-mei=真 aut-affil-num=2 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Phenol reaction kn-keyword=Phenol reaction en-keyword=Triticum kn-keyword=Triticum en-keyword=Chromosome kn-keyword=Chromosome END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1-2 article-no= start-page=61 end-page=68 dt-received= dt-revised= dt-accepted= dt-pub-year=1969 dt-pub=196903 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=コムギ縞萎縮病の病原ウイルス en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=井上忠男 kn-aut-sei=井上 kn-aut-mei=忠男 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=4 article-no= start-page=159 end-page=166 dt-received= dt-revised= dt-accepted= dt-pub-year=1965 dt-pub=196501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the mechanism of primary infection of wheat scab in relation to the environmental condition.

HaMV was transmitted by inoculation of sap to 6 of 41 species from 4 of 12 families. Systemic infection was cauded in Habenaria radiata, and local infection was produced in Chenopodium amaranticolor, C. quinoa, Spinacia olracea, Tetragonia expansa and Gomphrena globosa. HaMV was also transmitted by Myzus persicae in a non persistent manner, but not by Aphis gossypii. The virus has filamentous particles of c. 750×13nm. Sap from inoculated C. quinoa was infective after dilution to 10-5 but not 10-6, after 10 min at 60℃ but 65℃, or after 8-16 days at 20℃.In ultrathin sections of diseased leaves of Habenaria radiata and inoculated C. quinoa, virus particles were found to disperse in the cytoplasm. Cylindrical inclusions were present in the cytoplasm of infected cells, as pinwheels, scrolls or tubes. The inclusions observed in negatively stained crude sap preparations exhibited fine linear striation at about 5.2 nm intervals.The antiserum to HaMV produced by immunizing a rabbit had a titer of 1/512(precipitin test). HaMV showed distant serological relationships to potyvirus;alstroemeria mosaic virus, bean yellow mosaic virus, calanthe mild mosaic virus, clover yellow vein virus, dendrobium mosaic virus, freesia mosaic virus, turnip mosaic virus and watermelon mosaic virus 2. en-copyright= kn-copyright= en-aut-name=InouyeNarinobu en-aut-sei=Inouye en-aut-mei=Narinobu kn-aut-name=井上成信 kn-aut-sei=井上 kn-aut-mei=成信 aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name=前田孚憲 kn-aut-sei=前田 kn-aut-mei=孚憲 aut-affil-num=2 ORCID= en-aut-name=MitsuhataKoji en-aut-sei=Mitsuhata en-aut-mei=Koji kn-aut-name=光畑興二 kn-aut-sei=光畑 kn-aut-mei=興二 aut-affil-num=3 ORCID= en-aut-name=GaraI Wayan en-aut-sei=Gara en-aut-mei=I Wayan kn-aut-name=GaraI Wayan kn-aut-sei=Gara kn-aut-mei=I Wayan aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Habenaria orchid kn-keyword=Habenaria orchid en-keyword=Habenaria mosaic potyvirus kn-keyword=Habenaria mosaic potyvirus en-keyword=Habenaria mosaic disease kn-keyword=Habenaria mosaic disease END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=129 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=1998 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Purification and Properties of α-Glucodidase from Taro Tuber kn-title=サトイモのα-グルコシダーゼの精製と性質 en-subtitle= kn-subtitle= en-abstract=里芋塊茎を破砕し、その抽出液からα−グルコシダーゼを硫安分画、エチルアルコール分画、CM−セルロファインカラムトグラフィー、調製用ディスク電気泳動により約2,500倍に精製した。本酵素はニゲロースに対してはマルトースと同程度に作用したが、イソマルトースに対する作用は非常に弱く、トレハロースにはまったく作用しなかった。本酵素は少糖類や多糖類にもよく作用し、マルトヘキサオースや可溶性澱粉に対してはマルトースと同程度の相対速度比と、むしろ低めのKm値を示した。このことから本酵素が生体内で澱粉分解に密接に関わっていることが推測された。 kn-abstract=α-Gulcosidase (EC 3.2.1.20) has been purified 2,500-fold taro (Colocasia esculanta Shott) tuber by a procedure incluting fractionation with ammonium sulfate and ethyl alcohl, CM-cellulofine column chromatography, and preparative disc gel electrophoresis.

Melanaphis sacchari (Zehntner). (1) The kind of aphid appearing on the leaves of the sorghum varieties was only the sugarcane aphid, Melanaphis sacchari in the field. The number of aphids infesting a leaf was ca 0,30 and 3,500 in the resistant, moderately resistant and susceptible varieties at the middle of August, respectively. (2) The amount of leaf surface wax was approximately constant among these three varieties. (3) The total sugar content was slightly higher in the two resistant varieties than in the susceptible variety. (4) The total free amino acid concentration was higher in the two resistant varieties than in the susceptible variety. (5) These findings suggest that neither leaf surface wax nor nutritional components seem to affect the aphid populations on the leaves of the three sorghum varieties, showing that biogenic substances such as dhurrin, benzylalcohol, p-hydroxybenzaldehyde, aconitic acide, etc. may affect the aphid populations. en-copyright= kn-copyright= en-aut-name=TsumukiHisaaki en-aut-sei=Tsumuki en-aut-mei=Hisaaki kn-aut-name=積木久明 kn-aut-sei=積木 kn-aut-mei=久明 aut-affil-num=1 ORCID= en-aut-name=KanehisaKatsuo en-aut-sei=Kanehisa en-aut-mei=Katsuo kn-aut-name=兼久勝夫 kn-aut-sei=兼久 kn-aut-mei=勝夫 aut-affil-num=2 ORCID= en-aut-name=MoharramipourSaeid en-aut-sei=Moharramipour en-aut-mei=Saeid kn-aut-name=MoharramipourSaeid kn-aut-sei=Moharramipour kn-aut-mei=Saeid aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Sorghum kn-keyword=Sorghum en-keyword=Sugarcane aphid kn-keyword=Sugarcane aphid en-keyword=Melanaphis sacchari kn-keyword=Melanaphis sacchari en-keyword=Leaf surface wax kn-keyword=Leaf surface wax en-keyword=Amino acid kn-keyword=Amino acid END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=1 article-no= start-page=29 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=1986 dt-pub=198603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Measurements of Turbulent Transport of Carbon Dioxide over a Sorghum Field kn-title=ソルガム群落上での炭酸ガスフラックスの測定 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OhtakiEiji en-aut-sei=Ohtaki en-aut-mei=Eiji kn-aut-name=大滝英治 kn-aut-sei=大滝 kn-aut-mei=英治 aut-affil-num=1 ORCID= en-aut-name=MaitaniToshihiko en-aut-sei=Maitani en-aut-mei=Toshihiko kn-aut-name=米谷俊彦 kn-aut-sei=米谷 kn-aut-mei=俊彦 aut-affil-num=2 ORCID= en-aut-name=SeoTakuro en-aut-sei=Seo en-aut-mei=Takuro kn-aut-name=瀬尾琢郎 kn-aut-sei=瀬尾 kn-aut-mei=琢郎 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=1 article-no= start-page=19 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=1986 dt-pub=198603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Measurement of Vertical Profiles and Fluctuations of Air Temperature within and above a Sorghum Canopy kn-title=ソルガム群落内外における平均気温の高度分布と気温変動の測定 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MaitaniToshihiko en-aut-sei=Maitani en-aut-mei=Toshihiko kn-aut-name=米谷俊彦 kn-aut-sei=米谷 kn-aut-mei=俊彦 aut-affil-num=1 ORCID= en-aut-name=SeoTakuro en-aut-sei=Seo en-aut-mei=Takuro kn-aut-name=瀬尾琢郎 kn-aut-sei=瀬尾 kn-aut-mei=琢郎 aut-affil-num=2 ORCID= en-aut-name=SahashiKen en-aut-sei=Sahashi en-aut-mei=Ken kn-aut-name=佐橋謙 kn-aut-sei=佐橋 kn-aut-mei=謙 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=4 article-no= start-page=221 end-page=225 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=196703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A simple method for mass rearing of the seed-corn maggot, Hylemya platura MEIGEN (Diptera: Anthomyiidae) kn-title=タネバエHylemya platura Meigenの簡易大量飼育法 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MatsumotoY. en-aut-sei=Matsumoto en-aut-mei=Y. kn-aut-name=松本義明 kn-aut-sei=松本 kn-aut-mei=義明 aut-affil-num=1 ORCID= en-aut-name=SugiyamaS. en-aut-sei=Sugiyama en-aut-mei=S. kn-aut-name=杉山章平 kn-aut-sei=杉山 kn-aut-mei=章平 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=4 article-no= start-page=145 end-page=158 dt-received= dt-revised= dt-accepted= dt-pub-year=1969 dt-pub=19690326 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the relations between the seedling stage of Raphanus sativus L. and vernalization V.

The seeds of Echinochloa oryzicola Vasing., Ehinochloa crus-galli Beauv.var. formosensis Ohwi, Echinochloa crus-galli Beauv.var.crus-galli(awnless and awned type)and Oryza sativa L.(Akebono) were used. In 7000hPa, germination of rice,E. oryzicola and three varieties of E.crus-galli in all the solutions remarkedly decreased except for the case of E.crus-galli in the solution of sale on alternating temperature. The germination of rice and E.oryzicola was secreased markedly, and more markedly in a light condition than in a dark. In the salt solution in 7000hPa, the decreasing of germination of E.crus-galli was low. This species is distributed and grows in the upland and paddy field, while E.oryzicola and rice grow only in the paddy field. The decreade in germination of Echinochloa species with osmotic pressure seemed to be recoverde with salt or sugar solutions under alternating temperature, but the recovery of rice was not seen. In 700hPa or less, the distinct differences of germination were not seen among these plants species. en-copyright= kn-copyright= en-aut-name=NishiKatsuhisa en-aut-sei=Nishi en-aut-mei=Katsuhisa kn-aut-name=西克久 kn-aut-sei=西 kn-aut-mei=克久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=Genus Echinochloa kn-keyword=Genus Echinochloa en-keyword=Germination kn-keyword=Germination en-keyword=Osmotic pressure kn-keyword=Osmotic pressure END start-ver=1.4 cd-journal=joma no-vol=58 cd-vols= no-issue=3-4 article-no= start-page=181 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=1979 dt-pub=197912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Occurrence of branched ears at high nodal position of stems in barnyardgrass.

The molecular masses of α-glucosidases T,U,V,and W were 78,78,82 and 82kDa by SDS-PAGE, and 62,62,190,and 70kDa by gel filtration, respectively. α-Glucosidases Tand U showed similar enzymatic properties. The Km for soluble starch was about 10 times lower than that for maltose, and they had higher activity not only towards malto-oligosaccharides but also towards α-glucans. The optimum pH was 4.5-5.5 and about 50% of the activity remained after incubation at 71℃ for 20 min. On the other hand, α-glucosidases V and W showed similar enzymatic propreties. The Km for maltose was 3-4 times lower than for solble starch, and they had high activity toward malto-oligosaccharides but faint activity towards α-glucnas. The optimum pH was 4.5-5.0 and no activity was found after incubation at 70℃ for 20 min. However, anti-α-glucosidase V serum precipitated specifically with α-glucosidase V. en-copyright= kn-copyright= en-aut-name=SugimotoManabu en-aut-sei=Sugimoto en-aut-mei=Manabu kn-aut-name=杉本学 kn-aut-sei=杉本 kn-aut-mei=学 aut-affil-num=1 ORCID= en-aut-name=FuruiSatoshi en-aut-sei=Furui en-aut-mei=Satoshi kn-aut-name=古井聡 kn-aut-sei=古井 kn-aut-mei=聡 aut-affil-num=2 ORCID= en-aut-name=SuzukiYukio en-aut-sei=Suzuki en-aut-mei=Yukio kn-aut-name=鈴木幸雄 kn-aut-sei=鈴木 kn-aut-mei=幸雄 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=α-Glucosidase kn-keyword=α-Glucosidase en-keyword=Spinach kn-keyword=Spinach en-keyword=Seed kn-keyword=Seed en-keyword=Spinacia oleracea L. kn-keyword=Spinacia oleracea L. en-keyword=Molecular form kn-keyword=Molecular form END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=3 article-no= start-page=181 end-page=188 dt-received= dt-revised= dt-accepted= dt-pub-year=1970 dt-pub=197001 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=マツタケ発生林内微気象観測例 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高須謙一 kn-aut-sei=高須 kn-aut-mei=謙一 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=木村和義 kn-aut-sei=木村 kn-aut-mei=和義 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=則武赳夫 kn-aut-sei=則武 kn-aut-mei=赳夫 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=4 article-no= start-page=195 end-page=215 dt-received= dt-revised= dt-accepted= dt-pub-year=1977 dt-pub=197703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Ecological studies on water nutsedge (Cyperus serotinus Rottb.)

The mutation rate of topsin tolerant spores was 10-5~10-6 and was not affected by the irradiation of ultraviolet rays nor application of topsin to the culture medium. Highly tolerant strains were easily selected on the screening medium containing topsin. Finally topsin was not effective to the selected tolerant mutants. The topsin tolerance was parallel to "benrate" tolerance. The tolerance was transmitted through hyphae, conidium and ascospore. The growth rate of hyphae of the tolerant mutants was lower than that of the original strains, but the conidia formation and the virulence of the mutants were comparable to the original strains. Since the heavy application of fungicides may increase the fungicide-tolerant mutants, crop varieties resistant to scab disease must be developed. en-copyright= kn-copyright= en-aut-name=WuJiri en-aut-sei=Wu en-aut-mei=Jiri kn-aut-name=呉基日 kn-aut-sei=呉 kn-aut-mei=基日 aut-affil-num=1 ORCID= en-aut-name=TakedaKazuyoshi en-aut-sei=Takeda en-aut-mei=Kazuyoshi kn-aut-name=武田和義 kn-aut-sei=武田 kn-aut-mei=和義 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Fusarium spp. kn-keyword=Fusarium spp. en-keyword=Fungicide tolerance kn-keyword=Fungicide tolerance en-keyword=Mutation. kn-keyword=Mutation.
