Plants are frequently exposed to a plethora of unfavorable or even adverse conditions, called abiotic stresses, which lead to a series of morphological, physiological, biochemical, and molecular changes that prevent plants from reaching their full genetic potential, and hence limit the crop productivity. Abiotic stress is the principal cause of crop failure worldwide, dipping average yields for most major crops by more than 50%. A common consequence of abiotic stresses is that they result, at some stage of stress exposure, in an increased production of reactive oxygen species (ROS) and subsequent oxidative stress. To maintain growth and productivity, plants must adapt themselves to stress conditions and set up specific protective mechanisms, including the protective mechanisms against oxidative stress. The chief aim of this chapter is to make a survey of protection by means of antioxidant systems against oxidative stress in plants during the action of various abiotic stresses.
