Abstract

Stress is the unfavorable and external condition that affects a plant’s metabolism, growth, development, productivity and others physiological condition. Various kind of abiotic stresses like cold, heat, drought, salinity, metal stress, etc affected the normal development, growth, productivity and other function of the plant. To respond with its changed environmental factors, plants rearrange its morphological, metabolic, and genetic mechanism. Under abiotic stress plants at first changes its structural and functional aspects of cellular components. Various stress responsible genes are activated in this time so that plants can rapidly synthesize important proteins and other metabolites during abiotic stress. Plants employ multiple and alternative morphological, metabolic, and genetic approaches, so that they could survive from those adverse environmental conditions
