In contrast, higher plants do not require Se, and the question of whether Se is an essential element to plants remains controversial. Previous reports suggest that trace amounts of Se may serve a role in antioxidative mechanisms and partially reduce the adverse effects of cadmium on the growth. The aim of this work was to investigate novel physiological function of Se and Se-dependent regulatory factor in Arabidopsis thaliana seedlings. The influence of Se (sodium selenate) supplementation in the range of 0.1–100 μM on the biomass of Arabidopsis plants was studied 18 days after sowing. A significant decrease in the shoot fresh weight of Arabidopsis seedlings was noted at greater than 50 μM. However, the fresh weight of the seedlings grown in the medium with 0.5–5 μM Se significantly increased over that of seedlings grown without Se. There was significant effect of Se supplementation on the ATP content and respiration, as compared with control plants. In Arabidopsis seedlings grown in the medium with 1 μM Se, NAD dependent glyceraldehyde-3-phosphate dehydrogenase and triosephosphate isomerase activities were 1.5-fold higher than those in seedlings grown without Se.","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：2008～2010;   課題番号：20580066;   研究分野：農学;   科研費の分科・細目：農芸化学・植物栄養学・土壌学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","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_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/00247967"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"TAKEDA, TORU"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部; 講師"}]},"item_8_version_type_12":{"attribute_name":"版","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":"武田,  徹"},{"creatorName":"タケダ, トオル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3478","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00247967","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_20580066seika.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_20580066seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3141/files/KAKEN_20580066seika.pdf"},"version_id":"33506945-6052-414f-ba50-fe08062deb7a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"シロイヌナズナ","subitem_subject_scheme":"Other"},{"subitem_subject":"プロテオーム","subitem_subject_scheme":"Other"},{"subitem_subject":"微量元素","subitem_subject_scheme":"Other"},{"subitem_subject":"セレン","subitem_subject_scheme":"Other"},{"subitem_subject":"NAD依存グリセルアルデヒド-3-リン酸デヒドロゲナーゼ","subitem_subject_scheme":"Other"},{"subitem_subject":"トリオースリン酸イソメラーゼ","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":"シロイヌナズナにおけるセレンの新規生理機能とセレン調節因子の解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シロイヌナズナにおけるセレンの新規生理機能とセレン調節因子の解析"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3141","relation_version_is_last":true,"title":["シロイヌナズナにおけるセレンの新規生理機能とセレン調節因子の解析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:45:19.985952+00:00"}
