Two sets of near-isogenic lines (NILs) with allele 1 (a counterpart of allele 2) or 2 at each loci under two backgrounds were established. Then, grain filling, ADPglucose pyrophosphorylase (AGPase) activity, protein and gene expressions in developing endosperm were examined. Results showed that mainly APL2-2 and partly SUT1-2 obviously improved grain filling. This increase would be resulted from the increasing AGPase activity, and expression of APL2 and SUT1 proteins. Therefore, APL2-2 and SUT1-2 would be alleles for good gain-filling, although it depended on the environments and backgrounds. A novel cultivar of super-EHPT, “Tsubumasari”, having alleles 2 at all of the three loci, however, could not show\\\nhigher yield, due to lower grain filling. Further improvement of source strength of this cultivar should be needed for super-high yield.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2017～2019;   課題番号：17K07627;   研究分野：農学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究協力者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kato, Tsuneo"},{"subitem_text_language":"en","subitem_text_value":"Aoki, Naohiro"},{"subitem_text_language":"en","subitem_text_value":"Horibata, Akira"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学生物理工学部"},{"subitem_text_value":"東京大学大学院農学生命科学研究科; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"加藤, 恒雄"},{"creatorName":"カトウ, ツネオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43185","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70149748","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=70149748"}]},{"creatorNames":[{"creatorName":"青木, 直大"},{"creatorName":"アオキ, ナオヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43186","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70466811","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=70466811"}]},{"creatorNames":[{"creatorName":"堀端, 章"},{"creatorName":"ホリバタ, アキラ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43187","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":"2021-03-15"}],"displaytype":"detail","filename":"17K07627seika.pdf","filesize":[{"value":"134.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17K07627seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/21515/files/17K07627seika.pdf"},"version_id":"7b155ee4-b63b-4f55-ae54-5e4813390cb7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"イネ","subitem_subject_scheme":"Other"},{"subitem_subject":"極穂重型","subitem_subject_scheme":"Other"},{"subitem_subject":"登熟","subitem_subject_scheme":"Other"},{"subitem_subject":"ADPグルコースピロホスホリラーゼ","subitem_subject_scheme":"Other"},{"subitem_subject":"ショ糖トランスポーター","subitem_subject_scheme":"Other"},{"subitem_subject":"準同質遺伝子系統","subitem_subject_scheme":"Other"},{"subitem_subject":"超極穂重型","subitem_subject_scheme":"Other"},{"subitem_subject":"多収","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":"イネ良登熟型遺伝子の準同質遺伝子系統および新規超極穂重型系統を用いた機能検証","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イネ良登熟型遺伝子の準同質遺伝子系統および新規超極穂重型系統を用いた機能検証","subitem_title_language":"ja"},{"subitem_title":"Evaluation of the function of alleles for good grain filling in rice using near-isogenic lines and a novel super-extra-heavy panicle type","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4613"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-03-15"},"publish_date":"2021-03-15","publish_status":"0","recid":"21515","relation_version_is_last":true,"title":["イネ良登熟型遺伝子の準同質遺伝子系統および新規超極穂重型系統を用いた機能検証"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-14T07:06:48.363168+00:00"}
