Fig. 3. Seedling metal accumulation for wild-type (WT) and SHST1 overexpressing (SHST1-4C and SHST1-12C) Indian mustard plants. Shown is the shoot metal concentration after 7 d of growth on agar medium supplied with a metal(loid) to a concentration as indicated in Materials and Methods. Shown are means ± SE (n = 5 samples pooled from 14 plants each). The letters above the bars indicate statistically significant differences between groups (ANOVA with pairwise post-hoc analyses, = 0.05).
