Nipponbare) using 28Mg as a radioactive tracer. We used a multi-compartment transport\nbox, which separated the root region every 1 cm in order to apply 28Mg to a particular root region. Then, the\nroot region was defined as R-A, R-B, and R-C in order from the root tip region to the lateral root-developing\narea. The amount of 28Mg taken up in the R-C region in 15 min, 1 h, and 3 h was nearly three times as much\nas that of R-A and R-B. Thirty percent to 50% of 28Mg absorbed from R-C was transported toward the lower\npart of the root. Furthermore, when 28Mg was absorbed from R-C, it was detected only in the root part lower\nthan R-C after 5 min. In contrast, less than 5% of 28Mg absorbed from R-B was transported downward.\nThis characteristic uptake and transport behavior was not observed with 32P(phosphorus)-phosphate or\n45Ca (calcium). Our results demonstrate that Mg uptake and transport activity differ between root regions\nand further suggest that phloem loading of Mg occurs at R-C within minutes after uptake from the culture\nsolution. Then, Mg is transported toward the root tip directly without going up the shoot.\nKey words: magnesium, 28Mg tracer, multi-compartment transport box, rice root, uptake and transport.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/00380768.2013.768474","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0038-0768","subitem_source_identifier_type":"ISSN"}]},"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":"Kobayashi, Natsuko"}],"nameIdentifiers":[{"nameIdentifier":"464002","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwata, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"464003","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saito, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"464004","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"464005","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwata, Ren"}],"nameIdentifiers":[{"nameIdentifier":"464006","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanoi, Keitaro"}],"nameIdentifiers":[{"nameIdentifier":"464007","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Tomoko"}],"nameIdentifiers":[{"nameIdentifier":"464008","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"斉藤 貴之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464009","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 寿","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464010","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩田 錬","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464011","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田野井 慶太朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464012","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中西 友子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464013","nameIdentifierScheme":"WEKO"}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Different magnesium uptake and transport activity along the rice root axis revealed by a <sup>28</sup>Mg tracer experiments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Different magnesium uptake and transport activity along the rice root axis revealed by a <sup>28</sup>Mg tracer experiments"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-04"},"publish_date":"2013-06-04","publish_status":"0","recid":"46556","relation_version_is_last":true,"title":["Different magnesium uptake and transport activity along the rice root axis revealed by a <sup>28</sup>Mg tracer experiments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:50:21.037886+00:00"}
