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 \u003csup\u003e28\u003c/sup\u003eMg 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 \u003csup\u003e28\u003c/sup\u003eMg tracer experiments"}]}, "item_type_id": "8", "owner": "1", "path": ["1"], "permalink_uri": "https://repo.qst.go.jp/records/46556", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-06-04"}, "publish_date": "2013-06-04", "publish_status": "0", "recid": "46556", "relation": {}, "relation_version_is_last": true, "title": ["Different magnesium uptake and transport activity along the rice root axis revealed by a \u003csup\u003e28\u003c/sup\u003eMg tracer experiments"], "weko_shared_id": -1}
