A transformant expressing RelA/SpoT homolog (Sj-RSH) was found to have enhanced salt tolerance.   In E. coli, RelA/SpoT controlled the amount of guanosine tetraphosphate (ppGpp) and guanosin pentaphosphate (pppGpp), which are the effectors of the bacterial stringent response.   Complementation analysis using the relA mutant of E. coli showed that Sj-RSH conferred the phenotype associated with (p)ppGpp synthesis.   Furthermore, expression of Sj-RSH driven bt the GAL1 promoter also gave rise to enhanced salt tolerance in yeast.   Northern blot analysis of the yeast transformant revealed that the transcriptional levels of stress responsive genes including GPD1, VMA1, BMH1, HYP1 and HOG1 were clearly enhanced in the Sj-RSH transformant when compared with an empty vector transformant under stress-free and 1.5 M NaCl stress conditions.   These results suggested that (p)ppGpp synthesis mediated by plant RelA/SpoT homologs plays a critical role for the transcriptional induction of several stress responsive genes, directly or indirectly in yeast, and that the conserved stress-resistance system may exist in higher plants.","subitem_description_type":"Other"}]},"item_3_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_3_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_3_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_3_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"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":"Yamada, A"}],"nameIdentifiers":[{"nameIdentifier":"57121","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsutsumi, K"}],"nameIdentifiers":[{"nameIdentifier":"57122","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanimoto, S"}],"nameIdentifiers":[{"nameIdentifier":"57123","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozeki, Y"}],"nameIdentifiers":[{"nameIdentifier":"57124","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"salt tolerance, Suaeda japonica","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":"Plant RelA/SpoT Homolog Confers Salt Tolerance in Escherichia coli and Saccharomyces cerevisiae","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Plant RelA/SpoT Homolog Confers Salt Tolerance in Escherichia coli and Saccharomyces cerevisiae"}]},"item_type_id":"3","owner":"2","path":["191"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-02-28"},"publish_date":"2008-02-28","publish_status":"0","recid":"13442","relation_version_is_last":true,"title":["Plant RelA/SpoT Homolog Confers Salt Tolerance in Escherichia coli and Saccharomyces cerevisiae"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T17:21:17.682548+00:00"}
