Figure 6

Effect of metal treatments on the electrolyte leakage of leaves in transgenic lines. Electrolyte leakage was expressed in percentage (%) of total electrolyte leakage (A). Data represent means with ± SD (n = 3). Different lowercase letters in the figure indicate significant difference at P < 0.05 by Tukey’s test. Two-week-old plants were hydroponically grown and treated with 50 μM Cd, 350 μM Pb, 350 μM Zn, and 50 μM Co for seven days (B). For Pb treatment, plants were transferred to phosphate-free nutrient solution at least 12 hours prior to treatment.
