Abstract
Salinity causes disturbance in osmotic potential, imbalance in nutritional composition, and reduction in photosynthesis that reduces whole-plant growth and development. Amongst different strategies to overcome salt-induced toxicity, external application of mineral nutrients is a cost-effective and smart method. Sulfur (S) has substantial significance in relieving the toxic impacts of salt stress by increasing plant nutrients, water uptake, protein contents, and plant productivity. It is an essential constituent of different coenzymes, vitamins, and plant hormones. Various S metabolites are involved in developing salt tolerance by modulating various physiological and biochemical processes in plants. In the case of saline conditions, S helps in ionic homeostasis, optimizing water stress, regulation of mineral uptake, protection of photosynthetic apparatus, activating antioxidant machinery, reduction of electrolytic leakage and membrane stabilization. This review focuses on the significance of S in improving salt tolerance potential of plants by modulating various growth, physiological and biochemical processes. Moreover, the significance of various S metabolites and S salts with respect to salt tolerance has also been described.
