Molecular characterization of oxidative signaling pathway in plant response to environmental stress

我们确定了大约。800个基因响应叶绿体产生的活性氧物种(ROS)。我们发现了两个新的基因，分别命名为PSI1和PSS8，它们通过ROS在植物对氧化胁迫的反应中发挥重要作用。此外，对热休克转录因子A2(HsfA2)在环境胁迫下的表达分析表明，HsfA1d和HsfA1e调节HsfA2的表达以响应环境胁迫。

We identified approx. 800 genes responsive to reactive oxygen species (ROS) derived from chloroplasts. We found that two novel genes, named PSI1 and PSS8, are important for plant response to oxidative stress via ROS. Furthermore, the analysis of the expression of heat shock transcription factor A2 (HsfA2), a key regulator for stress response, under environmental stress indicated that HsfA1d and HsfA1e regulate HsfA2 expression in response to environmental stress.
