Chapter 10 - Targeting the Redox Regulatory Mechanisms for Abiotic Stress Tolerance in Crops

Abstract

Abiotic stress impacts on plants are inevitable, and are mainly the result of impairments in cellular redox homeostasis. In fact, abiotic stress-provoked elevations in reactive oxygen species (ROS) are the main driver of cellular redox homeostasis. In addition to reviewing ROS, their chemistry, and sites of production; this chapter highlights the dual roles of ROS in separate sections, and discusses in detail the role and modulation of major enzymatic and nonenzymatic components of antioxidant defense systems involved in cellular redox regulation in abiotic-stressed plants.
