However, these models do not indicate historical transitions in sexuality. Here, we investigate the evolution of bidirectional sex change and gonochorism by phylogenetic analysis using the mitochondrial gene of the gobiids Trimma (31 species), Priolepis (eight species), and Trimmatom (two species). Trimma and Priolepis formed a clade within the sister group Trimmatom. Gonadal histology and rearing experiments revealed that Trimma marinae, Trimma nasa, and Trimmatom spp. were gonochoric, whereas all other Trimma and Priolepis spp. were bidirectional sex changers or inferred ones. A maximum-likelihood reconstruction analysis demonstrated that the common ancestor of the three genera was gonochoristic. Bidirectional sex change probably evolved from gonochorism in a common ancestor of Trimma and Priolepis. As the gonads of bidirectional sex changers simultaneously contain mature ovarian and immature testicular components or vice versa, individuals are always potentially capable of functioning as females or males, respectively. Monogamy under low-density conditions may have been the ecological condition for the evolution of bidirectional sex change in a common ancestor. As T. marinae and T. nasa are a monophyletic group, gonochorism should have evolved from bidirectional sex change in a common ancestor."}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"16K07507"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Berlin Heidelberg"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00114-017-1434-z","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s00114-017-1434-z","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 魚類における配偶システムの系統進化と脳内神経葉ホルモン遺伝子に関する研究"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-16K07507/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 須之部友基 (東京海洋大学)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000090262336/","subitem_relation_type_select":"URI"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00281042","subitem_source_identifier_type":"ISSN"}]},"item_3_subject_62":{"attribute_name":"件名","attribute_value_mlt":[{"subitem_subject":"科学研究費研究成果"}]},"item_3_subject_64":{"attribute_name":"科学研究費研究課題","attribute_value_mlt":[{"subitem_subject":"魚類における配偶システムの系統進化と脳内神経葉ホルモン遺伝子に関する研究"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"須之部, 友基"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Tetsuya Sado"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kiyoshi Hagiwara"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hisaya Manabe"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Toshiyuki Suzuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yasuhisa Kobayashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Makoto Sakurai"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shin-ichi Dewa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Midori Matsuoka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akihiko Shinomiya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"福田, 和也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masaki Miya"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bidirectional sex change","subitem_subject_scheme":"Other"},{"subitem_subject":"Phylogenetic analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Size-advantage model","subitem_subject_scheme":"Other"},{"subitem_subject":"Low-density model","subitem_subject_scheme":"Other"},{"subitem_subject":"Mating system","subitem_subject_scheme":"Other"},{"subitem_subject":"Gobiidae","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article"}]},"item_title":"Evolution of bidirectional sex change and gonochorism in fishes of the gobiid genera Trimma, Priolepis, and Trimmatom","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evolution of bidirectional sex change and gonochorism in fishes of the gobiid genera Trimma, Priolepis, and Trimmatom"}]},"item_type_id":"3","owner":"15","path":["261","262","286"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-07"},"publish_date":"2019-01-07","publish_status":"0","recid":"1646","relation_version_is_last":true,"title":["Evolution of bidirectional sex change and gonochorism in fishes of the gobiid genera Trimma, Priolepis, and Trimmatom"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-25T10:45:57.069268+00:00"}
