Abstract

Plants are sessile organisms and face the adverse effect of environmental changes. They regulate the adaptations to these stresses through various mechanisms. Plant hormones are one of the most important regulators of abiotic stresses that control plant growth through modulation of several molecules, messengers and other signal transduction pathways. Most importantly, they regulate and maintain the cellular redox homeostasis and eventually the downstream metabolic processes. Recent developments in molecular biology have enhanced our understanding towards hormonal regulation of abiotic stress. Here, we discuss the major metabolism affected by abiotic stresses mainly drought, heat, salinity and cold and their effect on hormonal regulation. The mechanistic understanding is thus important for the crop improvement program.
