Regulation of plants metabolism in response to salt stress: an omics approach

In recent era, some man-made and natural activities are responsible for causing salt stress that affects each component of environment. Among several components, plant is one of the essential components, and with the consequence of excess salts accumulation in the environment their metabolic activities may get affected. Plants exhibit hyper-osmotic stress and ion disturbance in the presence of excess salt accumulation. To combat this stress situation, some metabolites/or stress-responsive gene(s) and proteins are synthesized by the plants to mitigate the salt toxicity. Therefore, to reduce the impact of salt stress on yield and other physiological activities of plants it is essential to know the whole pathway through which plant's metabolism get affected in the presence of salt. The present review is also dealing with the same objective and special focus is given to the omics tools, such as genomics, proteomics and metabolomics to discuss the different ways of tolerance mechanism in the plant system against salt toxicity.
