Abstract: Soil salinization is one of the major abiotic factors reducing crop productivity worldwide. The plasma membrane Na+/H+ antiporter plays an important role in plant salt tolerance because it is involved in Na+ exclusion in roots, long-distance Na+ transport in plants and the regulation of cellular K+, pH homeostasis and Ca2+ transport. In this review, we analyze recent advances in molecular structure and function, including expression and regulation of the plasma membrane Na+/H+ antiporter, and its role in plant salt tolerance.
