K⁺ and Na⁺ fluxes in root tissues of Arabidopsis before and after Salt treatment. Plant materials were subjected to 100 mM NaCl treatment for 24 h. K⁺ and Na⁺ fluxes in roots of wild-type and transformed plants without (a) or with (b) salt stress treatment are shown. The mean fluxes of K⁺ and Na⁺ without or with salt stress treatment were shown in c and d, respectively. The data shows the mean ± S.E. of triplicate experiments. Columns with different letters indicate significant differences at P < 0.05
