For this purpose, we have decided the procedure for space experiment in EMCS (European Modular Cultivation System), such as the optimal method of seed sowing, condition of plant cultivation, and methods of sample fixation and collection. We have also selected one tubulin mutant (tua 6) and one HMGR (3-Hydroxy-3-Methyl Glutaryl-CoA Reductase) mutant (hmg 1) in the Columbia background for space experiment. Hypergravity suppressed elongation growth, whereas it stimulated lateral expansion of stem organs. These mutants had thicker and shorter hypocotyls than wild-type even under 1 g conditions, and hypergravity did not affect their length or diameter, suggesting that the mutants are hypersensitive to the gravitational force. We expect that such defects of these mutants are rescued under microgravity conditions in space.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063338002","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-06-032","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部　ISS科学プロジェクト室"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency ISS Science Project Office, Institute of Space and Astronautical Science"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宇宙航空研究開発機構宇宙科学研究本部ISS科学プロジェクト室"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ISS Science Project Office, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency","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":"2020-01-16"}],"displaytype":"detail","filename":"63338002.pdf","filesize":[{"value":"707.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63338002.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5728/files/63338002.pdf"},"version_id":"f5cf6e14-792b-4033-82cf-722e06666057"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"微小管","subitem_subject_scheme":"Other"},{"subitem_subject":"突然変異体","subitem_subject_scheme":"Other"},{"subitem_subject":"細胞壁","subitem_subject_scheme":"Other"},{"subitem_subject":"シロイヌナズナ","subitem_subject_scheme":"Other"},{"subitem_subject":"抗重力反応","subitem_subject_scheme":"Other"},{"subitem_subject":"重力効果","subitem_subject_scheme":"Other"},{"subitem_subject":"重力屈性","subitem_subject_scheme":"Other"},{"subitem_subject":"微小重力","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝子発現","subitem_subject_scheme":"Other"},{"subitem_subject":"microtubule","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mutant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cell wall","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Arabidopsis thaliana","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravity resistance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitropism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microgravity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gene expression","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"植物の抗重力反応における微小管-原形質膜-細胞壁連絡の役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"植物の抗重力反応における微小管-原形質膜-細胞壁連絡の役割"}]},"item_type_id":"3","owner":"1","path":["1002","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5728","relation_version_is_last":true,"title":["植物の抗重力反応における微小管-原形質膜-細胞壁連絡の役割"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:33:24.483286+00:00"}
