ABSTRACT
The productivity of plants is greatly affected by variousenvironmental stresses. Drought is one of the major abiotic stresses which adversely affect the plant growth and development, causing severe losses in agricultural production. Wide variety of plant responses, ranging from cellular metabolism to changes in growth rates and crop yields are triggered by dehydration stress. Understanding the basis and mechanisms of physiological, biochemical and molecular responses to drought stress tolerance will be essential for a holistic perception of plant resistance mechanisms to water-limited conditions. This review reveals a brief description about perception of stress, strategies adapted by plants and responses of plants during drought.
Key words :
Abiotic stress, Drought tolerance.
