摘要：

在植物细胞中,线粒体ETC的复合物I和III是ROS产生的主要部位。大量证据表明,ROS可作为一普遍存在的信号分子在胁迫诱导植物PCD过程中起作用,而线粒体处于PCD调控的中心位置。

关键词： 活性氧;信号传导;细胞程序性死亡

Abstract: In plant cells,complexes I and III of mitochondrial electron transport chain(ETC) are major sites of reactive oxygen species(ROS) production.A lot of evidence suggested that ROS can act as ubiquitous signal molecules during stress-induced programmed cell death(PCD) in plants. Mitochondrion plays a role of central postiton.

Keywords: reactive oxygen species;signal transduction;programmed cell death
