However, nitrate is often distributed heterogeneously in natural soil. Plants, therefore, have a systemic long-distance signalling mechanism by which N starvation on one side of the root leads to a compensatory N uptake on the other N-rich side1,2. This systemic N acquisition response is triggered by a root-to-shoot mobile peptide hormone, C-TERMINALLY ENCODED PEPTIDE (CEP), originating from the N-starved roots3,4, but the molecular nature of the descending shoot-to-root signal remains elusive. Here, we show that phloem-specific polypeptides that are induced in leaves upon perception of root-derived CEP act as descending long-distance mobile signals translocated to each root. These shoot-derived polypeptides, which we named CEP DOWNSTREAM 1 (CEPD1) and CEPD2, upregulate the expression of the nitrate transporter gene NRT2.1 in roots specifically when nitrate is present in the rhizosphere. Arabidopsis plants deficient in this pathway show impaired systemic N acquisition response accompanied with N-deficiency symptoms. These fundamental mechanistic insights should provide a conceptual framework for understanding systemic nutrient acquisition responses in plants.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"http://doi.org/10.1038/nplants.2017.29"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/26929"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"nature","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1038/nplants.2017.29","subitem_relation_type_select":"DOI"}}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2055-026X","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ohkubo, Yuri","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"73313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Mina","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"73314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tabata, Ryo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"73315","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogawa-Ohnishi, Mari","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"73316","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsubayashi, Yoshikatsu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"73317","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":"2017-09-20"}],"displaytype":"detail","filename":"Nature_Plants_2017.pdf","filesize":[{"value":"7.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Nature_Plants_2017.pdf ファイル公開：2017/09/20","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/24707/files/Nature_Plants_2017.pdf"},"version_id":"902df68c-28d1-4c21-8943-5700b373a5e4"}]},"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":"Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["696"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-09-04"},"publish_date":"2017-09-04","publish_status":"0","recid":"24707","relation_version_is_last":true,"title":["Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:13:08.528277+00:00"}
