Plant Response and Tolerance to Abiotic Oxidative Stress : Mdpi AG : 9783036577821 : 3036577823 : 15 Jun 2023 : The survival of plants under stressful environments requires the study of the mechanisms that help in reversing the adverse impacts of reactive oxygen species (ROS) excessively generated under these conditions. Understanding the mechanisms helps in adopting strategies to induce such mechanisms for the better acclimation of plants. These ROS, if not scavenged, cause damage of cellular components, including lipids, proteins, nucleic acids, and metabolites, and, in extreme cases, even the death of cells in plants. Confronted with abiotic stress, there is an initial elevation in ROS that activates redox signaling to initiate defense in plants through the activation of antioxidant activity. The improvement in the capacity of antioxidant machinery is one of the essential strategies with which to develop tolerance and relieve the pressure of abiotic-stress-induced oxidative changes
