Previous molecular analyses of the auxin response pathway revealed that IAA and 2,4-D share a common mode of action to elicit downstream physiological responses. However, recent findings with 2,4-D specific mutants suggested that 2,4-D and IAA might also use distinct pathways to modulate Arabidopsis root growth. Using genetic and cellular approaches, we demonstrate that the distinct effects of 2,4-D and IAA on actin filament organization partly dictate the differential responses of roots to these two auxin analogues. 2,4-D but not IAA altered the actin structure in long term and short term assays. Analysis of the 2,4-D specific mutant aar1-1 revealed that Small Acidic Protein 1 (SMAP1) functions positively to facilitate the 2,4-D-induced depolymerization of actin. The ubiquitin proteasome mutants, tir1-1 and axr1-12, which show enhanced resistance to 2,4-D compared with IAA for root growth inhibition, were also found to have less disrupted actin filament networks after 2,4-D exposure. Consistently, chemical inhibitor of the ubiquitin proteasome pathway mitigated the disrupting effects of 2,4-D on the organization of actin filaments. Roots of the double mutant aar1-1 tir1-1 also showed enhanced resistance to 2,4-D-induced root growth inhibition and actin degradation compared with their respective parental lines. Collectively, these results suggest that the effects of 2,4-D on actin filament organization and root growth is mediated through synergistic interactions between SMAP1 and SCFTIR1 ubiquitin proteasome components.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1111/tpj.13433","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://onlinelibrary.wiley.com/doi/10.1111/tpj.13433/full"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://onlinelibrary.wiley.com/doi/10.1111/tpj.13433/full","subitem_relation_type_select":"URI"}}]},"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":"Maho, Takahashi"}],"nameIdentifiers":[{"nameIdentifier":"480462","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kana, Umetsu"}],"nameIdentifiers":[{"nameIdentifier":"480463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Yutaka"}],"nameIdentifiers":[{"nameIdentifier":"480464","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takumi, Higaki"}],"nameIdentifiers":[{"nameIdentifier":"480465","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Elison, Blancaflor"}],"nameIdentifiers":[{"nameIdentifier":"480466","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rahman, Abidur"}],"nameIdentifiers":[{"nameIdentifier":"480467","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大野 豊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480468","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":"SMALL ACIDIC PROTEIN 1 (SMAP1) and SCFTIR1 ubiquitin proteasome pathway act in concert to induce 2,4-dichlorophenoxyacetic acid-mediated alteration of actin in Arabidopsis roots","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SMALL ACIDIC PROTEIN 1 (SMAP1) and SCFTIR1 ubiquitin proteasome pathway act in concert to induce 2,4-dichlorophenoxyacetic acid-mediated alteration of actin in Arabidopsis roots"}]},"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":"47856","relation_version_is_last":true,"title":["SMALL ACIDIC PROTEIN 1 (SMAP1) and SCFTIR1 ubiquitin proteasome pathway act in concert to induce 2,4-dichlorophenoxyacetic acid-mediated alteration of actin in Arabidopsis roots"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:34:47.854339+00:00"}
