Co-overexpression of AtNHX1 and SOS1 could significantly reduce yield loss caused by the combined stresses of heat and salt, confirming the hypothesis that stacked overexpression of two genes could substantially improve tolerance against multiple stresses.
Title: Co-overexpressing a Plasma Membrane and a Vacuolar Membrane Sodium/Proton Antiporter Significantly Improves Salt Tolerance in Transgenic Arabidopsis Plants.

Tonoplast-localized NHX1 and NHX2 proteins are essential for active K+ uptake at the tonoplast, for turgor regulation, and for stomatal function.
Title: Ion exchangers NHX1 and NHX2 mediate active potassium uptake into vacuoles to regulate cell turgor and stomatal function in Arabidopsis.

Overexpression of AtNHX1 gene not only improved salt tolerance but also drought tolerance in transgenic groundnut.
Title: Enhanced expression of AtNHX1, in transgenic groundnut (Arachis hypogaea L.) improves salt and drought tolerence.

NHX1 and NHX2 mediate K+/H+ exchange to accumulate K+ in the vacuole. NHX1 and NHX2 function together to control cell expansion in vegetative tissues and male reproductive organs and are required for normal flower development.
Title: The Arabidopsis Na+/H+ antiporters NHX1 and NHX2 control vacuolar pH and K+ homeostasis to regulate growth, flower development, and reproduction.

Poisoning by toxic cations in the endosome/prevacuolar compartment is detrimental for cell functions, but it can be alleviated by improving the discrimination of transported alkali cations by the resident cation/H(+) antiporter.
Title: Mutants of the Arabidopsis thaliana cation/H+ antiporter AtNHX1 conferring increased salt tolerance in yeast: the endosome/prevacuolar compartment is a target for salt toxicity.
