Plants are sessile organisms and unlike animals, cannot run away from adverse environmental conditions. Therefore, they have evolved sophisticated signaling and protective systems to overcome sub-lethal stress situations. Although, effect of stress on physiology and morphology were studied earlier, the research on molecular mechanisms of stress response is albeit new. Studies at the molecular level on stress physiology reveal that, many stress-induced pathways converge downstream or interact significantly. Abiotic stress factors regulate the extent and pattern of developmental programme. The timing of transition from vegetative to flowering phase, which is vital for survival and reproductive success, is often altered under various stresses. Unraveling the mechanisms by which different environmental stresses induce their effects and how tolerance to stress is achieved is an active area of research. Enhancing stress tolerance, especially in crop plants is an area of prime importance. In this review, we focus on stress responses induced by temperatures, high and low light intensities, UV radiation, drought and salinity stress and summarize the recent advancements by highlighting the underlying molecular pathways and processes.
