活性氧与植物细胞程序性死亡

Reactive Oxygen Species and Programmed Cell Death in Higher Plants

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。

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.
