The molecular mechanisms of environmental stress responses by redox regulation in plants

为了全面理解“植物通过氧化还原调节的环境胁迫响应的分子机制”，分析了（1）通过叶绿体产生的ROS的氧化信号传导和（2）营养素水解酶的生理作用的分子机制。我们发现：（1）氧化信号通路由叶绿体H2 O2特异性调控表达的基因调控;（2）营养素水解酶通过代谢各种核苷-2-磷酸衍生物调节应激反应机制。

To comprehensively understand "the molecular mechanisms of environmental stress responses by redox regulation in plants", the molecular mechanisms of (1) oxidative signaling via ROS produced from chloroplasts and (2) physiological roles of Nudix hydrolases were analyzed. We found that (1) oxidative signaling pathways modulated by the genes whose expressions are specifically regulated by chloroplastic H202 and (2) Nudix hydrolases regulate stress responsive mechanisms via metabolisms of various nucleoside-2 phosphate derivatives.
