This situation makes cultivation of plants tolerant to high stress more crucial. Therefore, current studies are mostly focused on the explaining the tolerance mechanisms of highly drought resistant plants and protecting and transforming of the plant genetic sources. In this paper, drought effects on the plants, plant physiological reactions to drought and adaptation mechanisms of the plants are explained by referring important researches done in the recent years.
