Abstract
The projected rise in the global temperature and water scarcity will increase the frequency and intensity of heat and drought stresses. Agriculture is the main sector that is severely affected by these stresses and going to threaten global food security. Mungbean is the major summer-season food legume and of paramount importance because of its protein-rich seeds and have the ability to restore soil fertility. But these stresses adversely affect the overall growth and development of this crop as revealed through altered morphology, physiology, enzymatic activities, and eventually declined its quality as well as quantity. Reproductive stage is extensively studied and more susceptible toward heat stress as various processes such as pollen germination, pollen load, pollen tube growth, stigma receptivity, ovule fertility, and seed filling are reduced to a much extent leading to poor yield. The present review summarizes the effects of heat and drought stress on the vegetative, reproductive growth, physiological functions, and cellular activities of mungbean. Furthermore, defense mechanisms employed by the plants that comprise elevated productions of HSPs, antioxidants, osmolytes, and secondary metabolites are also considered. Based upon such responses of the plants, various approaches, which can be employed by the breeders for developing stress-tolerant varieties comprise physiological, biochemical, molecular traits, and agronomic strategies. These approaches would prove to be valuable for getting insights into the physiological and molecular mechanisms governing heat and drought tolerance and will pave the way for engineering the plants.
