Effect of Cd on the growth of wild-type (WT) and GS-overexpressing (GS2, GS7, and GS10) Indian mustard seedlings grown for 7 d on agar medium containing different concentrations of CdSO₄. A, Root length (the averages and se values of 50 seedlings). B, Five representative seedlings from each line, grown on 0.20 mm CdSO₄ (digitized image). Using analysis of variance, each of the transgenic lines was shown to be significantly different (P < 0.05) from the wild type (WT) at each Cd concentration, with the exception of line GS10 at 0.25 mm Cd.
