Figure 2.

Growth phenotypes of vacuolar nhx knockout mutants grown under supplemental NaCl and KCl. Six-day-old wild-type (WT) and knockout mutant plants were transplanted into modified MS medium (SP medium) supplemented with 30 mm NaCl or KCl. A to R, Images of 18-d-old plants. Bar = 2 cm. S, Fresh weights measured after 19 d of growth. Different letters above the bars indicate significant differences using one-way ANOVA with Tukey’s lsd separation test (P ≤ 0.05). Values are means ± se (n = 23–40).
