Abstract: Autophagy is a highly conserved biological progress in degradation of the cell components and has key roles in starvation, senescence and infection by pathogens. Moreover, reactive oxygen species (ROS) is a byproduct of higher plants during normal and stress conditions and plays an important role in regulation of growth and development and programmed cell death during stress response. Recent research has shown that ROS and autophagy both regulate programmed cell death in the hypersensitive reaction during infection by pathogens, growth and development and stress adaptation. We discuss the signal interaction between ROS and autophagy in plants, including species and characteristics of ROS, the molecular basis of plant autophagy, and  functions of ROS in plant autophagy.
