MsSOS2 positively regulates Na⁺ and K⁺ homeostasis. Control or salt treated leaves were pooled from 12 plants of the indicated genotypes per biological replicate and three biological replicates used to element analyses (n = 3). (a) Leaf Na concentration. (b) Leaf K concentration. Error bars represent the standard error (± SE). For statistical analysis, a two-way ANOVA followed by a Tukey’s HSD test was used to determine significant differences in leaf Na concentration (a) and leaf K concentration (b), between and among the indicated genotypes. In panels a and b, different letters above the error bars indicate a significant difference (P < 0.05), whereas the same letters indicate no significant difference.
