AB  - Climate change poses a substantial threat to global crop yield. Moreover, crop production is likely to reduce in the near future because of increasing average temperatures, widespread extreme climate events, and the loss of agricultural land. Abiotic stresses are the major factors limiting the growth and development of various crops worldwide. They cause the buildup of reactive oxygen species (ROS), which leads to cellular damage in a variety of subcellular compartments in plants. The metabolic rate of ROS is critical for crop yield, development, acclimation, and survival under a continuously changing environment. The modulation and enhancement of the expression of genes that encode ROS detoxifying enzymes are commonly used to increase the tolerance against abiotic stresses. Under stressful conditions, however, both enzymatic and nonenzymatic antioxidant systems maintain the balance between ROS elimination and production. At low concentrations, ROS play a signaling role and is important for a variety of biological processes, such as rapid cell growth and differentiation. The consequence of ROS toxicity is the ROS-activated cell damage triggered by the activation of signaling pathways, such as MAPKS and other calcium-dependent pathways. In this review, recent progress on the unfavorable effects of ROS, antioxidant defense mechanisms participating in ROS detoxification in various abiotic stresses, and cross-talk between different signaling pathways have been discussed. Furthermore, advancements in the molecular perspective of ROS-mediated antioxidant defense of plants under abiotic stresses have been discussed.
