A tracer experiment using nutrient solutions supplemented with 42K and 137Cs revealed that the ratio of the root\u2019s K+ uptake rate to its Cs+ uptake rate was 7\u201311 times higher than the K+\u00a0:\u00a0Cs+ 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+\u00a0:\u00a0137Cs+ ratio in the shoots was 4.28 times higher than the value in the roots. However, the 42K+\u00a0:\u00a0137Cs+ 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\u00a0h, 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_type": "Abstract"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "CSIRO Publishing"}]}, "item_2_select_14": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Graduate School of Agricultural and Life Sciences, The University of Tokyo"}, {"subitem_text_value": "Department of Plant Microbe Interactions, Max Planck Institute for Plant Breeding Research"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kobayashi, Natsuko I."}], "nameIdentifiers": [{"nameIdentifier": "2707", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sugita, Ryohei"}], "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."}], "nameIdentifiers": [{"nameIdentifier": "2711", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "FP15245.pdf", "filesize": [{"value": "1.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1500000.0, "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "cesium", "subitem_subject_scheme": "Other"}, {"subitem_subject": "channel blocker", "subitem_subject_scheme": "Other"}, {"subitem_subject": "deficiency", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ion uptake", "subitem_subject_scheme": "Other"}, {"subitem_subject": "live-imaging", "subitem_subject_scheme": "Other"}, {"subitem_subject": "selectivity", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Tracer experiment using 42K+ and 137Cs+ revealed the different transport rates of potassium and caesium within rice roots"}]}, "item_type_id": "2", "owner": "1", "path": ["9/10/11", "27/38/39"], "permalink_uri": "http://hdl.handle.net/2261/59076", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2016-01-13"}, "publish_date": "2016-01-13", "publish_status": "0", "recid": "721", "relation": {}, "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_shared_id": null}
