Analysis of ion content in transgenic and WT tobacco plants.

<p>(A) Na⁺ content in the leaves of transgenic and WT plants. (B) K⁺ content in the leaves of transgenic and WT plants. (C) Na⁺/K⁺ ratio in the leaves of transgenic and WT plants. The leaves were exposed to 0, 100 or 200 mM NaCl for 3 weeks of salinity treatment. Values are mean ± SE (n = 3). Different letters on the top of bars indicate significant differences at P<0.05 level as determined by Duncan’s multiple range test (DMRT). The results are representative of similar results obtained from two independent experiments.
