In seedlings of two short root mutants, RM1 and RM2, root length was 30 to 50% of the wild type ‘Oochikara', while a significant difference was not observed between the mutants and the wild type in plant height, number of roots and number of root hairs. In the root, final cell length in the mutants was about 60% of the wild type suggesting that the short root phenotype is mainly based on defective cell elongation. In root length, the F1 plants between the mutants and between those and the wild type were short and normal, respectively, while the F2 plants segregated into normal and short, giving a good fit to a 3:1 ratio. The F2 between the mutants did not segregate normal plants. These results show that the short root is controlled by a recessive gene, which is symbolized as srt-1.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"イネ品種オオチカラのM2幼植物集団から根伸長が野生型（原品種）より劣っている変異体を選抜し，その後代を用いて特性解析を行った。短根突然変異体RM1及びRM2幼植物の根長は野生型の30-50%であったが，草丈や根数，根毛数はほぼ同じであった。根の皮層細胞の大きさを観察したところ，細胞伸長を停止した分化領域のRM1及びRM2における細胞長は野生型の約60%であり，RM1及びRM2の短根性が主に細胞長の短小化によることを示していた。RM1及びRM2と野生型とのF1幼植物の根長はいずれも野生型とほぼ同じであり，いずれのF2幼植物集団でも野生型と短根型が3:1に分離した。なお，RM1とRM2とのF2幼植物はすべて短根型であった。これらの結果は，RM1及びRM2の短根性は単因子劣性の遺伝子によるものであり，RM1及びRM2は同一の遺伝子座の突然変異に起因することを示唆している。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japanese Society of Breeding","subitem_publisher_language":"en"},{"subitem_publisher":"日本育種学会 ","subitem_publisher_language":"ja"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"120004117303","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1270/jsbbs1951.47.121","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである","subitem_rights_language":"ja"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11353132","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-7610","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"3364"}]},"item_10001_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_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":[{"creatorAlternatives":[{"creatorAlternative":"一井, 真比古","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"一井, 眞比古","creatorNameLang":"ja"},{"creatorName":"イチイ, マサヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Ichii, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"石川, 道夫","creatorNameLang":"ja"},{"creatorName":"イシカワ, ミチオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ishikawa, Michio","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":"2020-11-27"}],"displaytype":"detail","filename":"AA11353132_47_2_121.pdf","filesize":[{"value":"962.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA11353132_47_2_121","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/518/files/AA11353132_47_2_121.pdf"},"version_id":"3ac61994-cb8a-4bb2-bf31-6b101cb6504d"}]},"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":"イネ短根突然変異体の遺伝解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イネ短根突然変異体の遺伝解析","subitem_title_language":"ja"},{"subitem_title":"Genetic analysis of newly induced short-root mutants in rice (Oryza Sativa L.)","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"11","path":["2"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-27"},"publish_date":"2012-03-27","publish_status":"0","recid":"518","relation_version_is_last":true,"title":["イネ短根突然変異体の遺伝解析"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-11-16T00:33:08.772501+00:00"}
