In the era of unpredictable climate variability, abiotic stresses in general and salt stress, in particular, have become critical issues on the agenda of plant scientists and policy makers. Salt stress, with its detrimental effects on plant health and crop productivity, ranks first. However, nanotechnological approaches could be candidates for the mitigation of the effects of salt stress, as is the case in a large number of documents. In this regard, by supplying the plants with silver nanoparticles, the harmful effects caused by salt stress can be buffered to a considerable extent. Significantly, it was highlighted that continuous exposure to silver nanoparticles could be a promising option in this context, as the silver nanoparticles are more stable in low saline water. As with other nanoparticles, silver nanoparticles have received a great deal of attention for their potential applications in plant science. The relevant nanomaterials can improve plant health and productivity when applied at low concentration. Following exposure to silver nanoparticles in salt-stressed plants, significant changes in physiological, biochemical and molecular endpoints were reported. Of the responses, the maintained ratio of Na/K, decreased level of stress indices, enhanced activities of antioxidant enzymes, improved redox status, enhanced photosynthetic attributes, triggered stress memory and finally improved plant health are the reported endpoints. In this chapter, we have a review and discussion of the latest reports on the interaction between silver nanoparticles and salt stress. We then concluded the chapter with questions that need to be addressed in future plant science studies.
