Plant age, cold acclimation, and plant hormones affected the resistance. Old plants had higher resistance than young plants. This meant that the young leaves of old plants had higher resistance than the young leaves of young plants. The resistance was also increased by seven days of cold acclimation. Light was necessary during cold acclimation, but the intensity and color of the light had no influence. Additionally, the plant hormones abscisic acid and salicylic acid increased the resistance. The mechanisms of resistance to the spread of Pythium snow rot were also investigated. Phenylalanine ammonia lyase (PAL) activity in the leaf blades of barley influenced the resistance. The increase in the PAL activity of plants that had undergone cold acclimation treatment was greater than that of untreated plants. The total phenol and lignin contents, which were controlled by PAL, were higher than in the untreated plant. The increase in the resistance was inhibited by PAL inhibitors. The increase in methanol soluble sugar, which was observed with the cold acclimation treatment, was not a direct cause of the resistance.\n","subitem_description_type":"Abstract"},{"subitem_description":"オオムギの耐雪機構解明のために耐雪性に影響する要因、および雪害の主要な原因である雪腐病に対する抵抗性と体内成分の関係を検討した。耐雪性に及ぼす播種期の影響は大きく、葉齢が進んだ個体ほど耐雪性が高かった。この耐雪性の増加は雪腐病抵抗性の増加と積雪下の低温暗黒湿潤条件に対する抵抗性の増加により生じた。さらに、主要な雪腐病菌である褐色雪腐病の抵抗性を侵入抵抗性と拡大抵抗性に分けて検討すると、両抵抗性とも葉齢の進んだ個体で高く、かつ、上位葉の抵抗性が下位葉に比べ高かった。褐色雪腐病拡大抵抗性は低温順化によっても増加し、7日間の処理で有意に増加した。低温順化処理には全期間で明条件 (12時間日長) が必要であったが、光の強さ、波長の影響は認められなかった。植物ホルモンのうちアブシジン酸、サリチル酸の葉面散布により抵抗性が増加したが、フェニルアラニンアンモニアリアーゼ (PAL) の阻害剤を散布すると抵抗性が増加しなかった。低温順化処理による抵抗性の増加に関与する体内成分を検討したところ、PAL活性の増加が認められ、PALと関連する全フェノール含量、リグニン含量が増加した。また、PALの阻害剤が低温順化による抵抗性増加を打ち消すことから、PAL活性が褐色雪腐病拡大抵抗性と関係があることが明らかとなった。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001243","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・食品産業技術総合研究機構 東北農業研究センター"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001243","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3379","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡邊 , 好昭"},{"creatorName":"ワタナベ, ヨシアキ","creatorNameLang":"ja-Kana"},{"creatorName":"WATANABE, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-09"}],"displaytype":"detail","filename":"tarc_report_No112p41-83p.pdf","filesize":[{"value":"4.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tarc_report_No112p41-83p.pdf","url":"https://repository.naro.go.jp/record/1276/files/tarc_report_No112p41-83p.pdf"},"version_id":"60b9002b-4e30-448c-a2be-bfe4490fdab9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"オオムギ","subitem_subject_scheme":"Other"},{"subitem_subject":"雪害","subitem_subject_scheme":"Other"},{"subitem_subject":"褐色雪腐病","subitem_subject_scheme":"Other"},{"subitem_subject":"抵抗性","subitem_subject_scheme":"Other"},{"subitem_subject":"葉齢","subitem_subject_scheme":"Other"},{"subitem_subject":"低温順化","subitem_subject_scheme":"Other"},{"subitem_subject":"フェニルアラニンアンモニアリアーゼ","subitem_subject_scheme":"Other"},{"subitem_subject":"barley","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"snow damage","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pythium snow rot","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resistance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"age","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cold acclimation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phenylalanine ammonia-lyase","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"オオムギの耐雪性機構、特に褐色雪腐病に対する抵抗性機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"オオムギの耐雪性機構、特に褐色雪腐病に対する抵抗性機構の解明"},{"subitem_title":"Mechanisms of Snow Tolerance and Resistance to Pythium Snow Rot in Winter Barley","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["188"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"1276","relation_version_is_last":true,"title":["オオムギの耐雪性機構、特に褐色雪腐病に対する抵抗性機構の解明"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T23:07:32.218346+00:00"}
