We focused on flavonoids, which are the chief compounds of the extracts, and studied mechanisms for their preparation and control. It was confirmed that the amounts of flavonol in ginkgo leaves rapidly increased when leaves opened and then gradually reduced after opening. Furthermore, entire base sequences of a chalcone synthase (CHS), which is a commencing compound for flavonoid, were determined using the genomic library. The sequences had G-box, seen frequently in light inducibility genes. Then, the sequences of mRNA prepared from embryos in light irradiation and in the dark were compared. While both embryos had the same sequences, determined from the genomic library, the different sequences were checked from embryos in light irradiation. Ginkgo trees seem to have two or more CHS genes reacting or not to a light stimulus. These results indicate that flavonol biosynthesis in ginkgo leaves is induced by light irradiation and is controlled by enzymes, including CHS, for flavonoids biosynthesis.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53424","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Aizawa, Eishi"}]},{"nameIdentifiers":[{"nameIdentifier":"53425","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kaneyuki, Tamijiro"}]},{"nameIdentifiers":[{"nameIdentifier":"53426","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Terada, Tamami"}]},{"nameIdentifiers":[{"nameIdentifier":"53427","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Samejima, Masahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"53428","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kamoda, Shigehiro"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The University of Tokyo Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科生物材料科学専攻"},{"subitem_text_value":"独立行政法人国際協力機構"},{"subitem_text_value":"日本製紙株式会社"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属演習林樹芸研究所"},{"subitem_text_value":"Department of Biomaterial Sciences, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Japan International Cooperation Agency"},{"subitem_text_value":"Nippon Paper Industries Co., Ltd."},{"subitem_text_value":"Arboricultural Research Institute, The University of Tokyo Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"会沢, 栄志"}],"nameIdentifiers":[{"nameIdentifier":"53419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"兼行, 民治郎"}],"nameIdentifiers":[{"nameIdentifier":"53420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"寺田, 珠実"}],"nameIdentifiers":[{"nameIdentifier":"53421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鮫島, 正浩"}],"nameIdentifiers":[{"nameIdentifier":"53422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鴨田, 重裕"}],"nameIdentifiers":[{"nameIdentifier":"53423","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh129003.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh129003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25233/files/esrh129003.pdf"},"version_id":"f8bb2eff-a06f-4214-ba49-71a734ae3321"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ginkgo","subitem_subject_scheme":"Other"},{"subitem_subject":"leaf extract","subitem_subject_scheme":"Other"},{"subitem_subject":"flavonoid","subitem_subject_scheme":"Other"},{"subitem_subject":"chalcon synthase（CHS）","subitem_subject_scheme":"Other"},{"subitem_subject":"light irradiation","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"イチョウにおけるフラボノイドの生成と制御機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イチョウにおけるフラボノイドの生成と制御機構"}]},"item_type_id":"4","owner":"1","path":["2484","2483"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-05"},"publish_date":"2013-08-05","publish_status":"0","recid":"25233","relation_version_is_last":true,"title":["イチョウにおけるフラボノイドの生成と制御機構"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:34.725801+00:00"}
