Fig. 4. Mature plant metal tolerance for wild-type (WT) and SHST1 overexpressing (SHST1-4C and SHST1-12C) Indian mustard plants. Shown is the ratio of plant fresh weight when grown on medium containing metal(loid) relative to its fresh weight on control medium. The form and concentration used for each metal(loid) is described in Materials and Methods. Shown are means ± SE (n = 10). The letters above the bars indicate statistically significant differences between groups (ANOVA with pairwise post-hoc analyses, 
= 0.05).
