In Arabidopsis, DNA double-strand breaks (DSBs) reduce root meristem size in a SOG1-dependent manner. SOG1 is a key transcription factor controlling the response to DNA damage. However, the underlying mechanism remains largely unknown. In this study, we found that treatment with the DSB inducer zeocin increased the accumulation of H2O2 in root tips. Chromatin immunoprecipitation analysis showed that SOG1 directly binds to the promoter of FMO1, which encodes a flavin-containing monooxygenase and is associated with the production of reactive oxygen species (ROS), H2O2 in particular. Indeed, zeocin induced the expression of FMO1 in a SOG1-dependent manner, and neither the sog1 nor the fmo1 knockout mutant exhibited higher H2O2 accumulation in root tips. Consequently, both sog1 and fmo1 could tolerate exposure to zeocin, in terms of root growth and the maintenance of the meristem size. However, transgenic plants over-expressing FMO1 also accumulated H2O2 in response to zeocin exposure, suggesting that other ROS-synthesis genes are also involved in the regulation of ROS production. We conclude that SOG1-mediated regulation of ROS homeostasis plays a key role in the reduction of root meristem size under DNA stress conditions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_publisher_10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley","subitem_publisher_language":"en"}]},"item_7_relation_15":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"26033196","subitem_relation_type_select":"PMID"}}]},"item_7_relation_17":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1111/gtc.12255","subitem_relation_type_select":"DOI"}}]},"item_7_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2015 The Molecular Biology Society of Japan and Wiley Publishing Asia Pty Ltd","subitem_rights_language":"en"},{"subitem_rights":"This is the peer reviewed version of the following article: [Genes to Cells, 20(8):636-646], which has been published in final form at [https://doi.org/10.1111/gtc.12255].
