Although the sex of most animals is determined by genetic information, sex-determining genes had been identified only in mammals, several flies, and the worm Caenorhabditis elegans until the recent discovery of DMY (DM-domain gene on the Y chromosome) in the sex-determining region on the Y chromosome of the teleost fish medaka, Oryzias latipes . We identified, for the first time in non-mammalian vertebrates, DMY, as the sex-determining gene of medaka. In tilapia,, Oreochromis niloticus , Foxl2/endogenous estrogens act as the natural inducers of ovarian differentiation, while DMRT1 may be important for testicular differentiation. In the protogynous wrasse, a rapid decline in serum estradiol-17beta levels may be an initial trigger of the female-to-male sex change.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_26_107","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"日本農学文献記事索引（AgriKnowledge）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010770099","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KOBAYASHI, Tohru","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"小林, 亨","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"コバヤシ, トオル","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"KOBAYASHI","familyNameLang":"en"},{"familyName":"小林","familyNameLang":"ja"},{"familyName":"コバヤシ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tohru","givenNameLang":"en"},{"givenName":"亨","givenNameLang":"ja"},{"givenName":"トオル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1859","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30221972","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30221972"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_26_107.pdf","filesize":[{"value":"642.5 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010878/files/fra_k_26_107.pdf"},"version_id":"8326f2bd-a1f0-4bfd-9930-fdcd364edd4c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sex determination; sex differentiation; DMY; DMRT1; estrogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"魚類の生殖腺性分化機構研究の現状","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"魚類の生殖腺性分化機構研究の現状","subitem_title_language":"ja"},{"subitem_title":"The mechanisms of gonadal sex determination and differentiation in fish","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1724310835301"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-02"},"publish_date":"2024-10-02","publish_status":"0","recid":"2010878","relation_version_is_last":true,"title":["魚類の生殖腺性分化機構研究の現状"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-11-01T01:58:19.968421+00:00"}
