Defoliation often decreases flower number in the following spring. To understand the underlying molecular mechanism, we investigated the effect of defoliation on a floweringrelated gene, citrus FLOWERING LOCUS T (CiFT). To determine the effect of defoliation period on CiFT expression, potted satsuma mandarin trees (Citrus unshiu Marc.) were completely defoliated at different time while growing at 15℃, the floral-inductive temperature. After 2.5 months at 15℃, CiFT　expression was higher in the stems of trees that retained their leaves for longer periods. These results　indicated that early defoliation suppressed CiFT expression in the stem. To determine how leaf number affected CiFT expression, potted trees were defoliated to different degrees and grown at 15℃ for one month. CiFT expression in the stem was strongly and positively correlated with leaf number, indicating that a decrease in leaf number suppressed CiFT expression in the stem. In both experiments, floral induction at the end of 15℃ treatment was estimated by forcing the trees to sprout at 25℃. Floral induction was suppressed by early or extensive defoliation, corresponding with the changes in CiFT expression.\n","subitem_description_type":"Abstract"},{"subitem_description":"常緑性であるカンキツ樹は, 寒害や潮風害, 乾燥にさらされ時々落葉する. 落葉はしばしば翌春の花数を減少させる. 落葉による花成抑制の分子機構を明らかにするために, 我々は花成制御遺伝子CiFTの発現に及ぼす落葉の影響を調査した. CiFTの発現における着葉期間の影響を調査した実験では, 花成誘導温度である15℃に置かれた鉢植えのウンシュウミカン樹から異なる時期にすべての葉が切除された. 15℃に移してから2.5ヶ月目において, CiFTはより長期間着葉していた樹の茎組織で高く発現する傾向にあった. このことは早期の摘葉が茎のCiFTの発現を抑制することを示している. CiFTの発現における葉数の影響を調査した実験では, 鉢植え樹が異なる葉数を持つように調整し, 15℃に置いた. 15℃に置いてから1ヶ月目に, 茎におけるCiFTの発現は葉数と正の高い相関を示した. 両実験において, 15℃処理終了時点での花成を25℃において強制的に発芽させた後に観察される花芽数によって評価した. 花成は早期の摘葉および大量の摘葉によって抑制され, CiFTの発現変動と一致していた. \n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002043","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・食品産業技術総合研究機構 果樹研究所"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002043","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3549","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"西川, 芙美恵"},{"creatorName":"ニシカワ, フミエ","creatorNameLang":"ja-Kana"},{"creatorName":"NISHIKAWA, Fumie","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"岩崎, 光徳"},{"creatorName":"イワサキ, ミツノリ","creatorNameLang":"ja-Kana"},{"creatorName":"IWASAKI, Mitsunori","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"深町, 浩"},{"creatorName":"フカマチ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"FUKAMACHI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"遠藤, 朋子"},{"creatorName":"エンドウ, トモコ","creatorNameLang":"ja-Kana"},{"creatorName":"ENDO, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-20"}],"displaytype":"detail","filename":"nifs_report_No15p1-6p.pdf","filesize":[{"value":"194.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nifs_report_No15p1-6p.pdf","url":"https://repository.naro.go.jp/record/2138/files/nifs_report_No15p1-6p.pdf"},"version_id":"40fad29c-6bd6-439b-8baf-aec4c84702ee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CiFT","subitem_subject_scheme":"Other"},{"subitem_subject":"Citrus unshiu Marc.","subitem_subject_scheme":"Other"},{"subitem_subject":"defoliation","subitem_subject_scheme":"Other"},{"subitem_subject":"floral induction","subitem_subject_scheme":"Other"},{"subitem_subject":"FT.","subitem_subject_scheme":"Other"},{"subitem_subject":"CiFT","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Citrus unshiu Marc.","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"defoliation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"floral induction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"FT.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"ウンシュウミカンにおいて摘葉はカンキツFLOWERING LOCUSTの発現を抑制する","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ウンシュウミカンにおいて摘葉はカンキツFLOWERING LOCUSTの発現を抑制する"},{"subitem_title":"Leaf Removal Suppresses Citrus FLOWERING LOCUS T Expression in Satsuma Mandarin","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["290"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"2138","relation_version_is_last":true,"title":["ウンシュウミカンにおいて摘葉はカンキツFLOWERING LOCUSTの発現を抑制する"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T15:57:57.246850+00:00"}
