Abstract: Drought stress is one of the major limitations to plant growth and development. In order to adapt to drought stress, responsive mechanism wolud be activated upon characteristic. The paper reviewed the reaserch progress of a series of mechanisms at the morphological, physiological, biochemical, cellular, and molecular levels to overcome water deficit or drought stress conditions. The paper also put forward prospect for the reaserch on the relationship between genetic and molecular mechanisms and drought resistance, which was expected to provided suggestions for futher research on stress resistance and genetic breeding.

Key words: drought stress, responsive mechanism, molecular response
