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", "download_preview_message": "", "file_order": 0, "filename": "25_2_108-116.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/23803", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-10-10"}, "publish_date": "2013-10-10", "publish_status": "0", "recid": "1982", "relation": {}, "relation_version_is_last": true, "title": ["Assimilation and Transport of Nitrogen in Tulip (Tulipa gesneriana) as Pursued by 15N"], "weko_shared_id": null}
