Abiotic stresses negatively impact plant physiology. These stressors induce a cascade of events (left portion of figure) which leads to the elevated production of toxic reactive oxygen species (ROS) and aging. Concurrently, the stresses upregulate antioxidant enzyme synthesis and endogenous melatonin production both of which provide protection against ROS. Additionally, the application of exogenous melatonin also provides protection against ROS and aging. Melatonin receptors (hyphenated box) are included in the cell membrane; however, these receptors have not heretofore been documented. CLH1/PAO = chlorophyll degradation-related genes; NAX1/AKT1 ion channel-related genes; SAGs = senescence associated genes.
