Drought is one the most common adverse environmental problem is increasing as a result of increasing population of world and intensive use of natural resources. Drought stress has major constraints to agricultural productivity worldwide, particularly in warm, arid and semi-arid areas. It adversely affects plants Morphological, Physiological and Biochemical processes and prolonged drought stress limits plant growth and productivity. The effect of drought stress at a whole plant level results non-normal physiological process that impact one or a combination of biological and environmental factors. That is why this review paper is mainly focused on recent information about the influence of water stress on plants, as well as its mechanisms of adaptation. It is shown that plants have evolved physiological and biochemical adaptations to cope with water stress. Plant used molecular mechanism to increase tolerance against drought are discussed. The literature analysed in this review shows an understanding of how these systems are regulated and upgrade the effect of drought stress on plants mechanism. The provided information needed to improve plants tolerance against drought stress by using biotechnological tools.
