Okayama1994エンドウ褐紋病菌サプレッサーの構造と作用機構ENToshiakiKato植物は諸々の微生物による攻撃から身を守るために様々な防御機構を備えているにも拘らず、ある種の微生物は特定の植物の防御機構を乗り越えて寄生する。植物の防御反応は、菌の細胞壁の分解物など、菌が植物に感染しようとする際に必然的に生じる"引金"物質を植物が認識して能動的に誘起きれる。奥ら(1977)は、エンドウ褐紋病菌について、"引金"物質が存在するにも拘らず、菌がエンドウの防御反応の起動を抑制し、感染に成功していることを突き止め、そのような役割を担う物質をサプレッサーと定義した。その後、エンドウ褐紋病菌以外の植物病原菌についてもサプレッサーの存在が報告され、サプレッサーが病原性決定因子として重要な役割を担っていることが広く認められるようになった。病原性決定因子としては、宿主特異的毒素(HST)が知られているが、その生産菌はAlternaria属菌とHelminthosporium 属菌に限られ、他の多くの植物病原菌の宿主特異性を扱うサプレッサーを生産しているものと考えられている。しかしながら、それらの構造や詳細な作用機構については解明されてはいなかった。エンドウ褐紋病菌サプレッサーの生理作用については、1)菌が寄生できる植物種に限って効果が認められ、2)ファイトアレキシンと呼ばれる抗菌性物質の蓄積阻害などにより、本来病原性のない菌の感染をも許すようになること、3)抵抗性反応に関与する一連の酵素の遺伝子発現を抑制(遅延)することが明らかにされており、サプレッサーは、単独処理した場合でも宿主組織に壊死を起こすことはなく、抵抗反応の抑制や感受化をもたらすという点でHSTとは大きく異なっている。サプレッサーの植物側の作用点としては、4)原形質膜ATPaseである可能性が高いことが推定されていた。本論文においては、エンドウ褐紋病菌胞子発芽液よりサプレツサーを単離・精製し、その化学構造を決定し、サプレッサー活性を担う化学構造の特定とサプレツサーの作用機作の解明について研究した。(1)褐紋病菌サプレッサーの精製および構造解析 エンドウ褐紋病菌胞子発芽液より、限外ろ過、ゲルろ過、SepPAK-C(18)、逆相カラム、イオン配位子カラムなどを用いて、2種類のサプレツサー(Supprescin A, B)を単離し、アミノ酸分析(組成および配列)、糖組成分析、核磁気共鳴法(NMR)にて化学構造をGalNAc-Ser-Ser-G ly, Gal-GalN Ac-Ser-Ser-Gly-Asp-Glu-Thrと決定し、各々Supprescin AおよびBと命名した。(2)掲紋病菌サプレッサーの生理活性 両Supprescinともエリシターによって誘導されるエンドウのファイトアレキシン(ピサチン)蓄積を抑制したが、原形質膜ATPase活性阻害(in vitro, in situ)と非病原菌の感染促進効果はSupprescin Bにのみ認められた。Supprescin Aは、Supprescin BによるATPase活性阻害の程度を低減する効果がみられたことより、両Supprescinに共通した化学構造がATPase分子への結合に深く関していることが示唆された。(3)サプレッサーとしての活性を担う化学構造とその作用機構 1) Supprescinのペプチド部分に関する検討:Supprescinのアミノ酸配列に準じて、化学合成した2~6残基の11種類のペプチドに関して、ピサチン蓄積抑制効果、原形質膜ATPase活性阻害効果(in vitro)、エンドウ褐紋病菌の感染に及ぼす効果を調べた結果、Supprescin Bのペプチド部分であるSer-Ser-Gly-Asp-Glu-Thrについては上記3つのサプレッサー活性が認められたことから、本ペプチド部分がサプレッサーとしての活性を担っていることが判明した。しかしながら、もとのSupprescin Bに比べて弱い効果であったことから、糖鎖部分の重要性が示唆された。また、両Supprescinに共通したペプチド部分であるSer-Ser-Glyは、ピサチン蓄積抑制の他にATPase活性阻害の効果が認められたことから、Supprescin AのATPase分子への結合を裏付ける結果であった。ATPase活性に関するカイネティクス解析の結果、Ser-Ser-Glyを含むペプチドは括抗型の阻害、Asp-Gluを含むペプチドは非拮抗型の阻害であることを明らかにし、後者は酸性ホスファターゼの活性をも阻害したことから、ATPase酵素分子のホスファターゼ部位へ作用していることが推定された。Supprescinないしその部分ペプチドが、界面活性剤存在下で超音波処理したエンドウ原形質膜画分におけるATPase活性を阻害したことは、それらが原形質膜ATPaseを直接阻害していることを示している。2) Supprescinの糖部分に関する検討:Supprescinを構成するGalおよびGalN Acは、サプレッサーによるピサチン蓄積の抑制を低減させる効果が認められ、さらに、GalN Acについてはエンドウ褐紋病菌の感染を阻害する効果も認められたことなどから、GalやGalN Acはサプレッサーの作用点への結合において、重要な役割を担っていることが示唆された。(4)エンドウ原形質膜ATPase遺伝子の解析 サプレッサーの標的分子と考えられたエンドウ原形質膜ATPaseについて、その遺伝子解析を実施した。既報の他種高等植物の原形質膜H(+)-ATPase遺伝子の塩基配列に基づいて設計したDNAプライマーセットを用いて、エンドウcDNAを鋳型としたPCR[Polymerase chain reaction]法により増幅したDNA断片をクローニングし、コード領域の約60%に相当する1.7kbpの塩基配列を決定した。その結果、他種高等植物の原形質膜ATPase遺伝子とは塩基配列で73~76 % 、アミノ酸配列で79~86%の高い相向性が認められた。塩基配列を決定した範囲に存在するATPaseの活性部位とみられるドメインのアミノ酸配列は完全に保存されていた。さらに、ATPaseの活性部位(特にATP結合部位およびホスファターゼ部位)には、GluないしAsp残基が重要であるとされていることから、Supprescin Bに存在するAsp-Glu配列がATP分子と直接結合するか、あるいはATPase分子の活性ドメインの機能を撹乱することによって活性阻害を引き起こしている可能性が考えられた。このように、植物病原菌はサプレッサーを生産して、宿主の防御反応を抑制することによって感染に成功している。サプレッサーの標的分子としてはいくつかの可能性が考えられたが、原形質膜ATPaseがその1つであることを明らかにした。今後、エンドウ細胞における原形質膜ATPaseの役割やその制御機構を明らかにすると共に、サプレッサーが結合する標的分子を直接的に同定することが重要な課題であろう。No

: Dynamics of Jane Austen's NovelsENKanakoYamanekiThis dissertation explores Jane Austen's six completed novels, Northanger Abb~9y (1818), Sense and Sensibility(1811), Pride and Prejudice (1813), Mansfield Park (1814), Emma (1815), and Persuasion (1818), from the perspectives of classicism and romanticism. It is imperative to investigate her works from these perspectives because she historically belongs to the time of transition from the classical period to the romantic. Although many critics tend to see mainly the notable aspects of classicism in all her novels except Persuasion, I dispute the
traditional assessment that Au sten is only a classicist. My dissertation attempts first to explore the classical and romantic aspects in Austen's works by examining her six novels chronologically, second to reveal the shift from her interest in only classicism to her emphasis on both classicism and romanticism, and third to show how and why she begins to accept romanticism in her later years. Finally, it seeks to conclude that Austen, who deepens her romantic tendency in Mansfield Park and Emma, attains an identity as both a classicist and a romanticist in Persuasion, and to evaluate the significance of such a new dynamic identity.No potential conflict of interest relevant to this article was reported.Acta Medica Okayama1996近代都市・農村社会事業の研究 岡山県地域を中心にENNo potential conflict of interest

を実現するために,水田生態系に対する撹乱的働きかけを最小限にとどめた不耕起水田において,マメ科緑肥作物で覆うことにより,合理的かつ適切な雑草管理の方向性を追求したものである.これらの研究成果の概要は以下の通りである.I. レンゲ草生マルチを活用した不耕起水稲作における雑草の発生消長 まず我が国で古くから水田冬作に緑肥作物として栽培されてきたレンゲを草生マルチの候補種とした.不耕起水田にレンゲを草生マルチとして活用した水稲直播栽培を3年間継続したところ,栽培試験の初年度は,レンゲはよく繁茂し冬生雑草の発生も少なかった.そして湛水後の夏生雑草の発生は,前年の慣行栽培時に多数発生したコナギが消滅したほか他の草種の発生も少なく,水稲収量も470kg/10a以上を得た.またレンゲ草生マルチをレンゲ開花期の5月中旬に除去すると, 湛水後に一年生のカヤツリグサ科やアゼナ属を主とした水田夏生一年生雑草の密度が顕著に増加し,レンゲマルチによってこれらの雑草の発生を抑制できることが明確となった.しかし2年目以降,レンゲ群落の衰退とスズメノテッポウ,ノミノフスマなどの冬生雑草の増加が認められ,それに伴いヒエ属などの水田夏生雑草の発生数も増加して水稲収量は激減した.従って,レンゲ草生マルチによる雑草管理の問題点として,(1)イヌビエやヒメタイヌビエなどのノビエの
発生に対しては抑制効果が劣ること (2)圃場に湛水を開始する時期が遅くなるとレンゲが枯死し,マルチ効果が薄れること (3)全く除草を行わないと次年度以降の発生ポテンシャルとなる埋土種子集団の増加を抑えきれないこと,を明らかにした.II.異なる種子深度および潅水条件下における数種の植物マルチ資材がヒメタイヌビエの発生に及ぼす影響 ヒエ属のヒメタイヌビエ種子を用いて,レンゲ,へアリーベッチ, シロクローバおよびヨシのマルチ資材と,マルチ量,種子埋土深度,そして海水条件の4要国を組み合わせて発生数の比較を試みた.分散分析(ANOVA)や数量化理論I類による解析の結果,ヒメタイヌビエ同子が地表面lに存在する場合にはマルチの存在によって有意に発生が抑制され,その抑制の度合いはマルチの量が多いほど,そして深水になるほど強まることが明らかになった.従って,マルチ草種としては現存量の多い草種ほど雑草の発生が制御できると考えられた.III. 草生マルチの雑草抑制能力と湛水時期との関係 1.レンゲ以外のマルチ草種の活用の可能性を検討するために,強いアレロパシーも報告されているマメ科一年生緑肥作物のへアリーベッチと多年生のシロクローバを圃場に栽培し,雑草抑制力をレンゲと比較した.その結果湛水時まで旺盛な生育を続けるシロクローバや,現存量がレンゲの約2倍あり,密な群落を
形成するために光遮蔽効果が枯死後も維持できるへアリーベッチが,レンゲよりも冬生雑草および湛水後の雑草の発生を抑えた.そしてへアリーベッチマルチ区に移植した水稲は登熟歩合や千粒重が高まり,488.6kg/10aの収量が得られた.2.湛水下のマルチが分解する過程で植物の発芽および生育に及ぼす影響をレタス種子を用いて検討したところ,枯死群落より生存群議への湛水で,また植物部位別では葉部から得た水抽出液が顕著にレタスの発芽を阻害することが明らかになった.そしてレタスの発芽および初期生育阻害は,水抽出液のECと関係があり,有機溶媒を用いた水抽出液の分画操作の結果,有機酸が阻害作用に関与していることが推察された.このことから,マルチ草種がまだ旺盛に生育し,葉部の比率が高い開花期頃までに湛水を開始すれば,雑草の発芽や生育を抑制する可能性が示唆された.IV.雑草防除法,耕起法および作付け様式の異なる水田における埋土種子および雑草発生消長の比較 雑草の埋土種子量と圃場の管理様式との関係を調べたところ,不耕起水田では埋土種子の分布が表層部に偏り,また除草剤連用水田や丹念に手取り除草を続けている圃場では,雑草の発生ポテンシャルが少ないことを把握した.そして積極的に雑草防除を行わない不耕起水田では,ヒエ属を中心に埋土種子量が多くなった.従って,草生マルチの活用による雑草管理においても,次年度以降の発生ポテンシャルの増加を抑えなければ,マルチで抑制できない雑草が増加することが示唆された.以上の試験結果に基づき,①初期生育がなるべく速やかで, 他雑草との競合に有利であること,②現存量が多く密度の高い群落を形成し,光遮蔽効果を保つこと,③ アレロパシー活性が高いこと,④湛水開始期まで生存していること,⑤水稲栽培期間中,マルチが残存すること,⑥連作が可能で,毎年安定して繁茂すること ⑥ 湛水による枯死以前に種子を生産し,自然更新すること,が不耕起水田の雑草管理に適した理想的な草生マルチの条件と考えられた.最後にこれらの結果をもとに,マルチ草種と水稲との競合も考慮しつつ,圃場への湛水が5月上旬以前に可能となる地域ではレンゲ,そして湛水開始時期が6月中旬以降となる地域では枯れ上がりが遅く乾田期間中のマルチ効果が維持でき
