Abstract
Drought resistance (DR) being a complex traits triggers a wide array of physiological responses in plants thus affecting the activity of various genes. Plants on the other hand respond to the ever changing environment in a complex way that allows them to react to different conditions at a given time. Therefore, the genetic control of tolerance to abiotic stress is not only complex but also influenced by other environmental factors at various stages of plant growth. Plants use multiple ways to respond to drought stress and have adapted to drought through physiological and morphological changes which are controlled by a cascade of diverse signals. Plant response to drought is also accompanied by activation of genes which are involved in both perceptions of drought stress and transmission of the stress signals. Other genes regulate transduction of stress signal and modulate gene expression. This paper highlights potential improvement of DR of crops in field trials though the biochemical and molecular basis though stress adaptation remains the major challenges for the genetic improvement of DR.
