Cation concentration in tissues of wild-type and IlVP-transgenic tobacco plants in response to salt stress. Na+ (a–c) and K+ (d–f) concentrations were measured after treatment for 7 days with different NaCl concentrations (0, 50, 100, and 200 mM). Each bar represents the mean (n = 7), and error bars indicate the standard deviation (SD). Columns with different letters indicate a significant difference at P < 0.05 (Duncan’s multiple range test).
