%X The imposition of environmental stress leads to increased production of reactive oxygen species (ROS) in plant cells,Which can damage proteins,membrane lipids,DNA and other cellular components.Plants have evolved enzymatic and no\|enzymatic protection mechanisms that efficiently scavenge ROS.Enzymatic detoxication system includes supero xide dismutase (SOD),ascorbate peroxidase (APX),catalase (CAT) and glutathione peroxidase (GAX);no\|enzymatic antioxidants inculude ascorbic acid,glutathione,mannitol and carotenoids,which occur in high concentracations in plants.The over\|expression and accumulation strategies of these antioxidants in plants have been followed up to now,and have gained many transgenic plants showing increased stress tolerance.
