Abstract

Drought stress affects crop productivity worldwide, it represents one of the major challenges to world food security. Drought stress effects on a different physiological process in the plant tissue, it inhibits the absorption of K+ ion, increases absorption of Na+ ion, and reduced cell soluble protein contents. There are negative effects on plant growth at various morphological, physiological, and Molecular bases, it reduces photosynthesis, affects plant water relations, disturbs plant nutrient relations, and consequently decreases crop productivity. Under drought conditions plant using various strategies includes drought escape, drought avoidance, and drought tolerance reduces, however, tolerant plants initiate various defense mechanisms at morphological, physiological and molecular basis to tolerate drought conditions.
