This species occurs in Japan only in two restricted areas : at the northernmost tip of Tsushima Island, and in the eastern Gifu Prefecture (Tono region) of central Honshu. In the Tono region, the habitat of C.retusus is becoming fragmented under the influence of human activity and each stand contains a few individuals of C.retusus, while the population on Tsushima consists of approximately 1000 individuals. From the fossil evedence, C.retusus has been distrubuted continuously including the both two regions, and the present distribution is apparently relic in Japan. In contrast to the Tono population, the population of Tsushima seems to be stable. Comparing the genetic diversity and differentiation of the populations between these two regions should shed light on how a relic woody long-lived plant keeps and/or looses its genetic diversity, and how a population differentiates from other disjunct populations.\nAllozyme electrophoresis of 18 loci for the Tono region indicated that 22.2% of the loci are polymorphic (P) with a gene diversity of (h) 0.087. The population of Tsushima has 38.9% polymorphic loci and gene diversity of 0.149. We could not find any spatial genetic structure of C.retusus in the Tono region by spatial autocorrelation analysis. These results suggest that considerable genetic variation is still present in the Tono region and the influence of the recent habitat fragmentation seems not so large, yet. Because C.retusus is a long-livied tree, the population history may hinder the effect of the fragmentation at present.\nThe genetic diversity (GST) between the populations of the Tono and Tsushima is 0.280, showing the genetic differentiation between these two regions has occurred.","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:08640884, 研究期間(年度):1996-1997","subitem_description_type":"Other"},{"subitem_description":"出典：「固有遺存植物における遺伝的多様性: アリル間系統関係の解析の試みとその適用」研究成果報告書　課題番号08640884\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　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00049890","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理学部"}]},"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=60184925"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60184925","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-08640884/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-08640884/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-08640884/086408841997kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-08640884/086408841997kenkyu_seika_hokoku_gaiyo/","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":"2018-01-29"}],"displaytype":"detail","filename":"SC-PR-UEDA-K-kaken 1998-5p.pdf","filesize":[{"value":"263.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-UEDA-K-kaken 1998-5p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/43548/files/SC-PR-UEDA-K-kaken 1998-5p.pdf"},"version_id":"f5e6ffde-20be-437b-8aa5-032fcab7cac4"}]},"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":"固有遺存植物における遺伝的多様性: アリル間系統関係の解析の試みとその適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"固有遺存植物における遺伝的多様性: アリル間系統関係の解析の試みとその適用"},{"subitem_title":"Genetic diversity as to endemic, relict plants","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2836"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-29"},"publish_date":"2018-01-29","publish_status":"0","recid":"43548","relation_version_is_last":true,"title":["固有遺存植物における遺伝的多様性: アリル間系統関係の解析の試みとその適用"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:49:54.405218+00:00"}
