The vacuolar Naþ, Kþ/Hþ antiporter, OsNHX1, plays an important
role in the compartmentalization of highly accumulated
cytosolic Naþ and Kþ into the vacuoles (Fukuda et al., 2004). The
expression of this OsNHX1 gene is regulated by the level of Naþ in
plants (Fukuda et al., 1999). In the present study, OsNHX1 was
differentially expressed in the roots and shoots of both Sakha 102
