Drought Tolerance In Plants: A Review

Yasha Nazir Butt

Drought is an environmental restraint for plants which would become more severe in coming years if effective measures won’t be taken. It is a condition of reduced or very low availability of water to plants for a prolonged period of time hence disturbing plant growth, development, water relations, and efficiency of many terrestrial plants. Plants acclimatize themselves to different sophisticated biochemical, physiological, morphological changes to overcome drought conditions. Crops are prone to high susceptibility towards decrease in grain yield, reduced transpiration, and changed hormonal balance regulated through mechanisms of activation of anti-oxidant defense system, stomatal pore regulation, and osmoregulation in plant tissues. With advances in drought tolerance and plant genetic engineering, many drought tolerant traits can be acquired
