Oxidative Stress in Plants Causes, Consequences and Tolerance by Shahid Umar, Naser A Anjum And Altaf Ahmed
Oxidative stress is a central factor in a number of biotic and abiotic stress phenomena that occurs when there is a serious imbalance in any plant cell compartment between the production of reactive oxygen species (ROS) and antioxidant defense, leading to physiological and metabolic changes. The presence of high concentration of ROS in cells causes oxidative damage to photosynthetic functions and vital bio-molecules, and disrupt cellular metabolism. Thus, it is important for plant cells to have tight control on the concentration of ROS. Plants possess to a variable extent antioxidant metabolites, enzymes and non-enzymes that have the ability to detoxify ROS thus, to protect the photosynthetic- and cellular functions against ROS-caused oxidative stress and to maintain optimum growth, development and productivity under changing environment.
