Non-Enzymatic Antioxidants in Stressed Plants: A Review

Plants are exposed to different ecological stress during their life cycle, and because of these tensions, free radicals shaped. Reactive oxygen species(ROS) have a fundamental ability support typical plant improvement tolerance. The disruption the proportionality ROS generation antioxidant defense systems is one primary effects biotic abiotic stress, resulting in an excess buildup oxidative damage plants. may combat this issue by producing ROS-neutralizing compounds, both enzymatic non-enzymatic mechanisms maintain proper ratio between detoxification. Ascorbic acid (AsA), glutathione (GSH), flavonoids, Vitamin E (α-tocopherols), carotenoids crucial antioxidants context, with high potential for performing variety activities plants under stressful unstressful conditions, addition scavenging ROS. This review illustrates main roles some subjected various types stresses.
