Abstract: The ROS(Reactive oxygen species)is a plant byproduct of aerobic metabolism,environmental stress also makes a large amount of a ROS accumulate in plant cells. Low concentrations of ROS can exist as a signaling molecule to induce the expression of defense genes and plant adaptation to the environment reaction. When the stress force in plant cells produce large amounts of reactive oxygen species, it will cause damage to intracellular macromolecules and other components, to impede normal plant metabolism and growth, and even death. Plants existence of active oxygen scavenging mechanism, the balance can be maintained within a certain range of reactive oxygen species. Studies have shown that the plants active oxygen scavenging mechanism can improve the resistance of plants. In this paper, an overview of the current dynamic of Reactive Oxygen Species, at the same time explore the application of plant active oxygen scavenging mechanism in improving plant stress resistance.

Key words: ROS, Plant Stress, tolerance
