Effect of drought stress on crop physiology: A mini-review

Global climate change, in the form of increasing temperature and fluctuating soil moisture conditions including drought stress, is projected to decrease the crop physiology of food crops over the next 50 years. Drought stress is an effect of considered as the lowering in the rate of respiration or decrease in the level of photosynthesis. This mini-review tells us the latest information about the drought stress and its effect on the growth of the plant with relation to photosynthesis and water and the mechanism of adaptation. There are numerous ways of the mechanism of adaptation that allows the plant to tolerate the drought stress condition. This mini-review we can prove the statement of different authors on the tolerance of drought stress and the slight changes in the environmental conditions may lead to the fast flexibility of the cell metabolism is the first and main step in the avoidance of drought stress.
