Salinity is becoming a major threat to plant productivity loss in agricultural system. Plants respond to saline environment by modulating the inherent mechanisms to adjust to the changing environment. The understanding of the mechanisms that plants operate under saline environment is essential beginning in efforts to reduce the adverse effects of salinity stress. The agricultural system is tightly linked with the fertilizer input and thus the judicious application of fertilizers is expected to lead positive effects in reversing the salinity effects. Sulfur is a macronutrient with essential roles in plant development under optimal and stressful environment. Several compounds are synthesized from sulfur metabolism useful in reversing the adverse effects of abiotic stress because of their free radicals scavenging property. Sulfur-containing metabolites, amino acids (cysteine and methionine), vitamins (biotin and thiamine), thioredoxin system, glutathione lipoic acid and glucosinolats have potential to promote or modify physiological and molecular processes under salinity stress in plants. Thus, modulation of sulfur metabolites production could alter physiological and molecular mechanisms to provide tolerance against salinity. The present review discusses the role of sulfur-containing compounds in modifying various physiological and molecular processes in plants to confer salinity tolerance in plants.

Salinity effects on nitrogen metabolism in plants – focusing on the activities of nitrogen metabolizing enzymes: A review (2018, background): “…reduction in chlorophyll content and photosynthesis, an increase in the production of reactive oxygen species (ROS), and all such alterations subsequently lead to decreased plant growth and development (Monteiro et al. 2011; Ahmad et al. 2013; Khan et al. 2014; Acosta-Motos et al. 2017).”
