Drought is the most serious stress which limits agricultural growth and its development and further leads to a great risk to the world food-security. Drought related stress mainly occurs in arid and semiarid regions, in the conditions of shortage of rainfall, intense temperature fluctuation, salinity, high intense light. The dry spell of weather over a certain period may lead to the conditions of drought stress in plants which adversely distress the plant-development and total yield of the plants. Plants have developed different morphological, biochemical and physiological response mechanisms to cope with these environmental stresses but are different in different species of the plants. Plants response to drought stress by a various mechanism like an escape, avoidance, tolerance, use of growth regulators and some molecules which helps them to survive under high and low temperature. In this review, we study the effect, mechanism and management of drought stress in plants. Here, we discuss various morphological, physiological and biochemical mechanisms which help to tolerate the drought stress in plants and promote them to grow and perform functions in drought stress conditions.
