On the contrary to other ferns, however, hybrids are quite rare in the Osmundaceae. In addition, genome sizes have been stable in the Osmundaceae since the Middle Jurassic (ca. 150 million years ago), thus there could be some mechanisms which hamper a hybrid formation in this family.\nIn this study, we showed in the Osmundaceae: 1) many species synaptically grow, 2) reproductive seasons are overlapped among species, 3) hybrid could be made by artificial crossing. Therefore, barrier for hybrid formation should be post-zygotic in the Osmundaceae. We hypothesized that the post-zygotic barrier would be a hybrid breakdown, which could be happened by loss of chromosome(s) derived from either of the parental species.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号: 15K07182, 研究期間(年度):2015-04-01 - 2019-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「低温依存的雑種形成が切り拓く植物多様性研究の新展開」課題番号15K07182\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K07182/15K07182seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00051891","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"大阪市立大学 / 金沢大学自然システム学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=70392537"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=70392537","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K07182/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15K07182/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K07182/15K07182seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15K07182/15K07182seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-04-24"}],"displaytype":"detail","filename":"SC-PR-YAMADA-T-kaken 2019-4p.pdf","filesize":[{"value":"506.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-YAMADA-T-kaken 2019-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45554/files/SC-PR-YAMADA-T-kaken 2019-4p.pdf"},"version_id":"02e4bc36-4929-487c-9672-59f13d09707c"}]},"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":"低温依存的雑種形成が切り拓く植物多様性研究の新展開","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低温依存的雑種形成が切り拓く植物多様性研究の新展開"},{"subitem_title":"Thermo-dependent hybridization will provide new insights for studies on how current plant diversity is established","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2815"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-04-24"},"publish_date":"2020-04-24","publish_status":"0","recid":"45554","relation_version_is_last":true,"title":["低温依存的雑種形成が切り拓く植物多様性研究の新展開"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:35:45.871432+00:00"}
