Growth of coleoptiles exposed to hypergravity for 2 to 4 days from germination stage was substantially reduced. The net amounts of cell wall polysaccharides of hypergravity-treated coleoptiles increased as much as those of 1 g control coleoptiles during the incubation period. As a result, the levels of cell wall polysaccharides per unit length of coleoptile, which mean the thickness of cell walls, largely increased under hypergravity conditions. In the hemicellulose fraction, a polysaccharide fraction extracted from cell walls with strong alkali, glucose (Glc), arabinose (Ara) and xylose (Xyl) were the major sugar components, and the ratios of Ara and Xyl to Glc were higher in hypergravity-treated coleoptiles than in control coleoptiles. Furthermore, the fractionation of hemicellulosic polymers into the neutral and acidic polymers by the anion-exchange column showed that the levels of acidic polymers (mainly composed of arabinoxylans) in cell walls of hypergravity-treated coleoptiles were higher than those of control coleoptiles. In addition to wall polysaccharides, the amounts of cell wall-bound phenolics, such as ferulic acid and diferulic acid, increased at the same extent in both hypergravity-treated and control coleoptiles. These results suggest that hypergravity stimuli from the germination stage do not restrict the net synthesis of cell wall constituents in wheat coleoptiles, although they bias the type of synthesized hemicellulosic polysaccharides. The stimulation of the synthesis of arabinoxylans may be involved in the structural changes, such as thickening of cell walls, under hypergravity conditions. These structural changes in cell walls may contribute to plant resistance to gravity stimuli.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046917039","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪市立大学 大学院理学研究科"},{"subitem_text_value":"大阪市立大学 大学院理学研究科"},{"subitem_text_value":"大阪市立大学 大学院理学研究科"},{"subitem_text_value":"富山大学 理学部　生物学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Osaka City University Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Osaka City University Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Osaka City University Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Toyama University Department of Biology, Faculty of Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"若林, 和幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"曽我, 康一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"保尊, 隆享"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神阪, 盛一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wakabayashi, Kazuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Soga, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hoson, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamisaka, Seiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"過重力","subitem_subject_scheme":"Other"},{"subitem_subject":"細胞壁","subitem_subject_scheme":"Other"},{"subitem_subject":"植物","subitem_subject_scheme":"Other"},{"subitem_subject":"植生成長","subitem_subject_scheme":"Other"},{"subitem_subject":"コムギ","subitem_subject_scheme":"Other"},{"subitem_subject":"セルローズ","subitem_subject_scheme":"Other"},{"subitem_subject":"糖","subitem_subject_scheme":"Other"},{"subitem_subject":"多糖澱粉","subitem_subject_scheme":"Other"},{"subitem_subject":"hypergravity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cell wall","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vegetation growth","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wheat","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cellulose","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sugar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polysaccharide","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"イネ科植物の細胞壁構造に対する過重力の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イネ科植物の細胞壁構造に対する過重力の影響"}]},"item_type_id":"5","owner":"1","path":["1647","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13844","relation_version_is_last":true,"title":["イネ科植物の細胞壁構造に対する過重力の影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:43:52.462765+00:00"}
