Abstract:

Global food output is being negatively impacted by salinity, which is regarded as a major abiotic constraint. Numerous studies have been conducted to identify the methods by which plants tolerate salt stress, and the results have shown some key enzymes and altered biochemical processes that may be responsible for agricultural plants’ resistance. Studies that have been carried out for the last tanners ordinarily have observed the development of salt tolerant cultivars via traditional means, as well as extemporized by modern epoch molecular tools and techniques. Environmental stresses considerably and notably affect the productivity of plants in several ways. Generally, plant growth and development is greatly affected by the process of osmotic stress under soil salinity and Na+ and Cl– ions are toxic as well as having injurious effects that results in the imbalance among SO42– and Mg2+ ions as well as significant nutrient elements in plants. As a number of mechanisms reveal the salinity stress response as well as salinity tolerance processes, the effect is called polygenic which includes beneficial compatible solutes or osmolytes, polyamines, reactive oxygen species (ROS) as well as antioxidant defensive processes, transport and compartmentalization of injurious toxic ions. In order to identify the cue factors regarding the particular retaliations or cumulating toxic ions, it is crucial to understand the whole process accountable for growth restriction as well as retarding production of plants with the further span of retaliating the same. The present review will try to summarize the physiological as well as antioxidant defense mechanisms in plants upon salt toxicity. Explaining salinity tolerance as well as its later perspectives and applications in screening for salt tolerance will also be a venture of the present study
