Abstract:NHX-type antiporters in the tonoplast increase the salt tolerance of plants and are thought to mediate compartmentalization of Na+ into vacuoles. However, all isoforms characterized so far catalyze both Na+/H+ and K+/H+ exchange and no conclusive evidence has been presented that NHX exchangers do in fact enhance compartmentalization of Na+ into vacuoles in vivo.
