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_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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "nature"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ohkubo, Yuri"}], "nameIdentifiers": [{"nameIdentifier": "73313", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Mina"}], "nameIdentifiers": [{"nameIdentifier": "73314", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tabata, Ryo"}], "nameIdentifiers": [{"nameIdentifier": "73315", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ogawa-Ohnishi, Mari"}], "nameIdentifiers": [{"nameIdentifier": "73316", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matsubayashi, Yoshikatsu"}], "nameIdentifiers": [{"nameIdentifier": "73317", "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": "2017-09-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Nature_Plants_2017.pdf", "filesize": [{"value": "7.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 7300000.0, "url": {"label": "Nature_Plants_2017.pdf \u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2017/09/20", "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": "\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": "Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition"}]}, "item_type_id": "10", "owner": "1", "path": ["336/695/696"], "permalink_uri": "http://hdl.handle.net/2237/26929", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-09-04"}, "publish_date": "2017-09-04", "publish_status": "0", "recid": "24707", "relation": {}, "relation_version_is_last": true, "title": ["Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition"], "weko_shared_id": null}
