Fragile\nsites are hot spots of mutation, which are usually selected against. In this sense, they are\nevolutionary useless. Here, we hypothesized that a genome has some benefit if it has fragile sites,\nespecially when the host species face environmental changes and has to adapt in a short time. To\ndemonstrate this, we investigated genomes of various species. For example, we found a number of\ngenes have been integrated in the genome of parasite plants, and there seem to be hotspots of\nintegration, where multiple genes are integrated (Kado Inann 2018 Genome Biol. Evol.). We also\ninvestigated the genome of domesticated horse, from which we found a number of regions that have\nchanged dramatically in the domestication process.","subitem_description_type":"Abstract"}]},"item_2_relation_11":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN(科学研究費補助金データーベース)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15H04403/","subitem_relation_type_select":"URI"}}]},"item_2_text_19":{"attribute_name":"研究分野","attribute_value_mlt":[{"subitem_text_value":"ゲノム進化"}]},"item_2_text_20":{"attribute_name":"研究種目","attribute_value_mlt":[{"subitem_text_value":"基盤研究（B）（一般）"}]},"item_2_text_5":{"attribute_name":"報告年度","attribute_value_mlt":[{"subitem_text_value":"2018"}]},"item_2_version_type_12":{"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":"印南, 秀樹"}],"nameIdentifiers":[{"nameIdentifier":"11246","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-07-06"}],"displaytype":"simple","filename":"15H04403seika.pdf","filesize":[{"value":"80.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"研究成果報告書","url":"https://ir.soken.ac.jp/record/6120/files/15H04403seika.pdf"},"version_id":"2d98197c-f101-4b74-a4bc-07c98b6bd170"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"適応進化","subitem_subject_scheme":"Other"},{"subitem_subject":"脆弱部位","subitem_subject_scheme":"Other"},{"subitem_subject":"突然変異ホットスポット","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":"ゲノムの脆弱部位を利用した適応進化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ゲノムの脆弱部位を利用した適応進化"},{"subitem_title":"Adaptive genome evolution through fragile sites","subitem_title_language":"en"}]},"item_type_id":"2","owner":"24","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-06"},"publish_date":"2020-07-06","publish_status":"0","recid":"6120","relation_version_is_last":true,"title":["ゲノムの脆弱部位を利用した適応進化"],"weko_creator_id":"24","weko_shared_id":-1},"updated":"2023-06-20T14:14:20.369689+00:00"}
