Arabidopsis seeds, heterozygous for the GLABRA1 (GL1) gene (GL1/gl1-1), were irradiated with 15.8 MeV/u neon ions (mean linear energy transfer (LET): 352 keV/μm), 17.3 MeV/u carbon ions (113 keV/μm), or 60Co gamma rays. The frequency and size of glabrous sectors generated because of inactivation of the GL1 allele were examined. The frequency and overall size of large deletions were evaluated based on the loss of heterozygosity of DNA markers using DNA isolated from glabrous tissue. Irrespective of the radiation properties, plants with mutant sectors were obtained at similar frequencies at the same effective dosage necessary for survival reduction. Ion beams tended to induce larger mutant sectors than gamma rays. The frequency of large deletions (> several kbp) increased as the LET value increased, with chromosome regions larger than 100 kbp lost in most large deletions. The distorted segregation ratio of glabrous plants in the progenies of irradiated GL1/gl1-1 plants suggested frequent occurrence of chromosome rearrangement, especially those subjected to neon ions. Exposure to ion beams with moderate LET values (30–110 keV/μm) is thought effective for inducing mutant sectors without causing extensive genetic damage.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nimb.2016.11.023","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷, 純宏"}],"nameIdentifiers":[{"nameIdentifier":"480455","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野澤, 樹"}],"nameIdentifiers":[{"nameIdentifier":"480456","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鳴海, 一成"}],"nameIdentifiers":[{"nameIdentifier":"480457","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yutaka"}],"nameIdentifiers":[{"nameIdentifier":"480458","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長谷 純宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480459","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野澤 樹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480460","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大野 豊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480461","nameIdentifierScheme":"WEKO"}]}]},"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":"Effects of ion beam irradiation on size of mutant sector and genetic damage in Arabidopsis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of ion beam irradiation on size of mutant sector and genetic damage in Arabidopsis"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-27"},"publish_date":"2017-04-27","publish_status":"0","recid":"47855","relation_version_is_last":true,"title":["Effects of ion beam irradiation on size of mutant sector and genetic damage in Arabidopsis"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:34:48.556866+00:00"}
