The oral and gut microbiota are associated with many disorders, including allergy. Few studies have addressed the oral and gut microbiota in dogs, although the skin microbiota has been studied relatively well in these animals. Here, we studied the AD-associated oral and gut microbiota in 16 healthy and nine AD dogs from a purebred Shiba Inu colony. We found that the diversity of the oral microbiota was significantly different among the dogs, whereas no significant difference was observed in the gut microbiota. Moreover, a differential abundance analysis detected the Family_XIII_AD3011_group (Anaerovoracaceae) in the gut microbiota of AD dogs; however, no bacterial taxa were detected in the oral microbiota. Third, the comparison of the microbial co-occurrence patterns between AD and healthy dogs identified differential networks in which the bacteria in the oral microbiota that were most strongly associated with AD were related with human periodontitis, whereas those in the gut microbiota were related with dysbiosis and gut inflammation. These results suggest that AD can alter the oral and gut microbiota in dogs. en-copyright= kn-copyright= en-aut-name=UchiyamaJumpei en-aut-sei=Uchiyama en-aut-mei=Jumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsumiTakafumi en-aut-sei=Osumi en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizukamiKeijiro en-aut-sei=Mizukami en-aut-mei=Keijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukuyamaTomoki en-aut-sei=Fukuyama en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShimaAyaka en-aut-sei=Shima en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UnnoAsaka en-aut-sei=Unno en-aut-mei=Asaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Takemura‐UchiyamaIyo en-aut-sei=Takemura‐Uchiyama en-aut-mei=Iyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UneYumi en-aut-sei=Une en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MurakamiHironobu en-aut-sei=Murakami en-aut-mei=Hironobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakaguchiMasahiro en-aut-sei=Sakaguchi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Internal Medicine, Division of Animal Life Science, Graduate School, Tokyo University of Agriculture and Technology kn-affil= affil-num=3 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=4 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=5 en-affil=Anicom Specialty Medical Institute Inc. kn-affil= affil-num=6 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=7 en-affil=Department of Bacteriology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Veterinary Medicine, Okayama University of Science kn-affil= affil-num=9 en-affil=School of Veterinary Medicine, Azabu University kn-affil= affil-num=10 en-affil=School of Veterinary Medicine, Azabu University kn-affil= en-keyword=oral kn-keyword=oral en-keyword=gut kn-keyword=gut en-keyword=microbiota kn-keyword=microbiota en-keyword=atopic dermatitis kn-keyword=atopic dermatitis en-keyword=Shiba Inu kn-keyword=Shiba Inu en-keyword=dog colony kn-keyword=dog colony en-keyword=canine kn-keyword=canine END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=6 article-no= start-page=1792 end-page=1800 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decrosslinking enables visualization of RNA-guided endonuclease-in situ labeling signals for DNA sequences in plant tissues en-subtitle= kn-subtitle= en-abstract= kn-abstract=Information about the positioning of individual loci in the nucleus and the status of epigenetic modifications at these loci in each cell contained in plant tissue increases our understanding of how cells in a tissue coordinate gene expression. To obtain such information, a less damaging method of visualizing DNA in tissue that can be used with immunohistochemistry is required. Recently, a less damaging DNA visualization method using the CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/associated caspase 9) system, named RNA-guided endonuclease-in situ labeling (RGEN-ISL), was reported. This system made it possible to visualize a target DNA locus in a nucleus fixed on a glass slide with a set of simple operations, but it could not be applied to cells in plant tissues. In this work, we have developed a modified RGEN-ISL method with decrosslinking that made it possible to simultaneously detect the DNA loci and immunohistochemistry signals, including histone modification, in various types of plant tissues and species. en-copyright= kn-copyright= en-aut-name=NagakiK. en-aut-sei=Nagaki en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamajiN. en-aut-sei=Yamaji en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Centromere kn-keyword=Centromere en-keyword=CRISPR/Cas9 kn-keyword=CRISPR/Cas9 en-keyword=epigenetic modifications kn-keyword=epigenetic modifications en-keyword=immunohistochemistry kn-keyword=immunohistochemistry en-keyword=in situ DNA visualization kn-keyword=in situ DNA visualization en-keyword=RNA-guided endonuclease-in situ labeling (RGEN-ISL) kn-keyword=RNA-guided endonuclease-in situ labeling (RGEN-ISL) en-keyword=telomere kn-keyword=telomere END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=10 article-no= start-page=2717 end-page=2725 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The tonoplast-localized transporter OsHMA3 plays an important role in maintaining Zn homeostasis in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order to respond to fluctuating zinc (Zn) in the environment, plants must have a system to control Zn homeostasis. However, how plants maintain an appropriate level of Zn during their growth and development is still poorly understood. In this study, we found that OsHMA3, a tonoplast-localized transporter for Zn/Cd, plays an important role in Zn homeostasis in rice. Accessions with the functional allele of OsHMA3 showed greater tolerance to high Zn than those with the non-functional allele based on root elongation test. A 67Zn-labeling experiment showed that accessions with loss of function of OsHMA3 had lower Zn accumulation in the roots but similar concentrations in the shoots compared with functional OsHMA3 accessions. When exposed to Zn-free growing medium, the concentration in the root cell sap was rapidly decreased in accessions with functional OsHMA3, but less dramatic changes were observed in non-functional accessions. A mobility experiment showed that more Zn in the roots was translocated to the shoots in accessions with functional OsHMA3. Higher expression levels of OsZIP4, OsZIP5, OsZIP8, and OsZIP10 were found in the roots of accessions with functional OsHMA3 in response to Zn deficiency. Taken together, our results indicate that OsHMA3 plays an important role in rice roots in both Zn detoxification and storage by sequestration into the vacuoles, depending on Zn concentration in the environment. en-copyright= kn-copyright= en-aut-name=CaiHongmei en-aut-sei=Cai en-aut-mei=Hongmei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=CheJing en-aut-sei=Che en-aut-mei=Jing kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaJian Feng en-aut-sei=Ma en-aut-mei=Jian Feng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=OsHMA3 kn-keyword=OsHMA3 en-keyword=vacuolar sequestration kn-keyword=vacuolar sequestration en-keyword=ZIP transporter kn-keyword=ZIP transporter en-keyword=Zn distribution kn-keyword=Zn distribution en-keyword= Zn root-to-shoot mobility kn-keyword= Zn root-to-shoot mobility en-keyword=Zn tolerance kn-keyword=Zn tolerance END
