Tulip roots accumulate a large amount of N (ca. 90 mgN/gDW) during winter, if N is available in the medium. The accumulated N in the roots originated mainly in absorbed N from the medium rather than from the bulb storage N. During the winter season, the accumulated N in some roots was not readily translocated to the other roots, suggesting that the nitrogen be accumulated independently in each root. The accumulated N remained in soluble forms, especially glutamine was a major constituent. After sprouting in spring, the accumulated N in the roots was rapidly consumed for growth of leaves and stems. Some part of this N was redistributed to bulblets as the plants got matured. The behavior of N accumulated in the roots during winter was basically similar to that of the bulb storage N. Thus, it may be concluded that the physiological role of the N accumulation in roots in to provide a sufficient amount of N required for a rapid growth of leaves immediately after sprouting. During this period, 4-methyleneglutamine was a major amino compound in leaves, stems and roots. The presence of this amide appeared to be a temporary storage of N in vegetative organs of tulip plants. The transport from of N in xylem was mostly glutamine, and 4-methyleneglutamine was not detected. A high accumulation (20-120 mg/gDW) of a novel organic acid, 2-ox-4-methy1-3-pentene-1, 5-dioic acid was found in leaves and stems. This acid seems to be a deamidation and deamination product of 4-methylenglutamine.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tropical Agriculture Research Center"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA0068709X","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00213551","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ohyama, Takuji"}],"nameIdentifiers":[{"nameIdentifier":"52","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":"2019-07-29"}],"displaytype":"detail","filename":"25_2_108-116.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25_2_108-116.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1982/files/25_2_108-116.pdf"},"version_id":"369628a0-fc43-45b2-a3f9-cf60309e13fc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"glutamine","subitem_subject_scheme":"Other"},{"subitem_subject":"labeled N","subitem_subject_scheme":"Other"},{"subitem_subject":"4-methyleneglutamin","subitem_subject_scheme":"Other"},{"subitem_subject":"nitrogen metabolis","subitem_subject_scheme":"Other"},{"subitem_subject":"root","subitem_subject_scheme":"Other"}]},"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":"Assimilation and Transport of Nitrogen in Tulip (Tulipa gesneriana) as Pursued by 15N","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Assimilation and Transport of Nitrogen in Tulip (Tulipa gesneriana) as Pursued by 15N"},{"subitem_title":"Assimilation and Transport of Nitrogen in Tulip (Tulipa gesneriana) as Pursued by 15N","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","487"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-10-10"},"publish_date":"2013-10-10","publish_status":"0","recid":"1982","relation_version_is_last":true,"title":["Assimilation and Transport of Nitrogen in Tulip (Tulipa gesneriana) as Pursued by 15N"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:49.023939+00:00"}
