Abstract:

Reactive oxygen species(ROS)are produced in different organelles in plants under both normal and stress conditions,such as the ROS production by respiration in mitochondria and photosynthesis in chloroplast. Although ROS are potentially toxic to cells,they can act as signaling molecules to activate signaling transduction network to trigger the physiological reactions inside organelles,thus to coordinate the metabolic functions and interactions in sub-organelles. Though these processes have been extensively studied,the role of ROS in plant subcellular communication has been sporadic. This article reviews the types of ROS and how they are produced. Particularly,how plant cells perceive and respond to ROS and how they transmit signals between and within cells are summarized. It will be conducive to understanding the role of ROS as signaling molecules in the communication among mitochondria,chloroplasts and nucleus.

Key words: reactive oxygen species, retrograde signal, mitochondria, chloroplasts
