Judging from mitochondrial Cytochrome b gene and nuclear microsatellite 7 markers, The male clams found in Shiga Prefecture not directly derived from hermaphrodite clams distributed in the same location. It is curious that mitochondrial DNA was shared by male and hermaphrodite, although nuclear 28SrDNA was completely different from male and hermaphrodite. These results suggested that the male might reproduce by fertilizing the eggs from hermaphrodite. In this case hermaphrodite clams may show androgenetic development. We also tried the cross experiment between males and hermaphrodites to get the evidence of replacement of nucleus during fertilization. Unfortunately we failed to obtain the active spermatozoa from males by spawning induction.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2011年度～2013年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"23570270","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"The origin and possible role of male in hermaphrodite androgenetic Corbicula clam and its genetic diversity by molecular tools"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古丸, 明","creatorNameLang":"ja"},{"creatorName":"KOMARU, Akira","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"河村, 功一","creatorNameLang":"ja"},{"creatorName":"KAWAMURA, Kouichi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"50K17522.pdf","filesize":[{"value":"84.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"50K17522.pdf","url":"https://mie-u.repo.nii.ac.jp/record/10764/files/50K17522.pdf"},"version_id":"050b5b90-98d3-4611-a4a2-9c065d69e4c6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"雌雄同体","subitem_subject_scheme":"Other"},{"subitem_subject":"雄性発生","subitem_subject_scheme":"Other"},{"subitem_subject":"系統類縁関係","subitem_subject_scheme":"Other"},{"subitem_subject":"クローン","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"分子遺伝学的手法による雄性発生シジミの起源と核ゲノムクローン性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"分子遺伝学的手法による雄性発生シジミの起源と核ゲノムクローン性に関する研究","subitem_title_language":"ja"}]},"item_type_id":"8","owner":"15","path":["1692755069483"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-15"},"publish_date":"2016-01-15","publish_status":"0","recid":"10764","relation_version_is_last":true,"title":["分子遺伝学的手法による雄性発生シジミの起源と核ゲノムクローン性に関する研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-20T23:48:55.758623+00:00"}
