A tracer experiment using nutrient solutions supplemented with 42K and 137Cs revealed that the ratio of the root’s K+ uptake rate to its Cs+ uptake rate was 7–11 times higher than the K+ : Cs+ concentration ratio in the solution, and the number was varied depending on the K concentration in the solution and also on the growth condition. After entering through the root tissues, the 42K+ : 137Cs+ ratio in the shoots was 4.28 times higher than the value in the roots. However, the 42K+ : 137Cs+ ratio in each leaf did not differ significantly, indicating that the primary transport of K+ and Cs+ in the shoots are similarly regulated. In contrast, among the radionuclides stored in the roots over 4 h, 30% of the 42K+ was exported from the roots over the following hour, whereas only 8% of 137Cs+ was exported. In addition, within the xylem, K+ was shown to travel slowly, whereas Cs+ passed quickly through the roots into the shoots. In conclusion, our study demonstrated very different transport patterns for the two ions in the root tissues.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"CSIRO Publishing"}]},"item_2_select_14":{"attribute_name":"item_2_select_14","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Plant Microbe Interactions, Max Planck Institute for Plant Breeding Research"},{"subitem_text_language":"en"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kobayashi, Natsuko I.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugita, Ryohei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobori, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"2709","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanoi, Keitaro"}],"nameIdentifiers":[{"nameIdentifier":"2710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Tomoko M.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2711","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":"2017-05-30"}],"displaytype":"detail","filename":"FP15245.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"FP15245.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/721/files/FP15245.pdf"},"version_id":"d1270857-0940-4999-a83d-98d6f2ccb4fb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"cesium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"channel blocker","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"deficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion uptake","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"live-imaging","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"selectivity","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":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Tracer experiment using 42K+ and 137Cs+ revealed the different transport rates of potassium and caesium within rice roots","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Tracer experiment using 42K+ and 137Cs+ revealed the different transport rates of potassium and caesium within rice roots","subitem_title_language":"en"}]},"item_type_id":"2","owner":"191","path":["39","10"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-01-13"},"publish_date":"2016-01-13","publish_status":"0","recid":"721","relation_version_is_last":true,"title":["Tracer experiment using 42K+ and 137Cs+ revealed the different transport rates of potassium and caesium within rice roots"],"weko_creator_id":"191","weko_shared_id":-1},"updated":"2026-01-16T01:46:10.234360+00:00"}
