Drought is one of the most important environmental stresses for plants, which leads to a significant reduction in agricultural production. In drought stress conditions, plants exhibit a variety of responses at the physiology and sub-cellular levels such as increased expression of the gene like dehydrines. They are categorized in Group 2  LEA proteins (Late Embryogenesis Abundant proteins that synthesize and accumulate in different plant tissues not only in response to stress, but also as part of a pre-planned phenomenon during the final stages of development of the seed has been proven. Different types of dehydrine molecules have been identified in Arabidopsis, clover and other plants.
