Growth inhibition (A) and shoot Cd concentrations (B) of wild-type (WT) and GS-overexpressing (GS7 and GS10) Indian mustard plants treated with 0.05 or 0.1 mm CdSO₄. In A, the parameter used for growth is the relative increase in fresh weight of Cd-treated plants as the percentage of untreated plants of the same line; this parameter was chosen to normalize the different initial fresh weights for plants from different lines. Values shown are the average and se of 12 replicates (A), or of 6 pooled samples from 2 plants each (B). P < 0.05 for GS7 versus the wild type, and not significant for GS10 versus the wild type (A and B). DW, Dry weight.
