As for the factors involved in this regulation in Euglena gracilis, we for the first time report here that ammonium ion specifically enhances step-down photophobic response, together with the effects of L-methionine-DL-sulfoximine (L-MSO), an inhibitor of ammonium assimilation, to specifically enhance step-up photophobic response. The apparent positive correlation between the degree of greening and the step-down photophobic response did not seem to reflect real causal relationship in view of the results with effects of gabaculine, an inhibitor of δ-aminolaevulinic acid (δ-ALA) formation. The transmission of stigma and step-down appearance did not show any correlation either, in contrast to a previous assumption by other authors. Cycloheximide (CHX), an inhibitor of eukaryotic protein synthesis, suppressed step-down appearance and enhanced step-up appearance, probably suggesting an involvement of some (newly synthesized) protein(s) specifically in the step-down photosignal detection and/or signal transduction process(es).","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford University Press "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1093/oxfordjournals.pcp.a029530"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1093/oxfordjournals.pcp.a029530 ","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2009 The Author"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00320781 ","subitem_source_identifier_type":"ISSN"}]},"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":"MATSUNAGA, Shigeru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASHI, Tetsuo "}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Masakatsu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUGAI, Michizo "}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HORI, Terumitsu "}],"nameIdentifiers":[{}]}]},"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":"Control by ammonium ion of the change from step-up to step-down photophobically responding cells in the flagellate alga Euglena gracilis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Control by ammonium ion of the change from step-up to step-down photophobically responding cells in the flagellate alga Euglena gracilis"},{"subitem_title":"Control by ammonium ion of the change from step-up to step-down photophobically responding cells in the flagellate alga Euglena gracilis","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["283"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-22"},"publish_date":"2013-08-22","publish_status":"0","recid":"3913","relation_version_is_last":true,"title":["Control by ammonium ion of the change from step-up to step-down photophobically responding cells in the flagellate alga Euglena gracilis"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2023-06-20T14:28:54.277146+00:00"}
