Cd tolerance and accumulation in roots and shoots of BjCET transgenic plants exposed to CdCl₂. (A–C) Quantitative analysis of root length (A), fresh root weight (B), and fresh shoot weight (C) of different genotype plantlets exposed to 200 μM CdCl₂ for 30 d. (D, E) Root and shoot Cd content (μg mg⁻¹ dry weight) of different genotype plantlets exposed to 200 μM CdCl₂ for 30 d, respectively. (F) Total Cd accumulated in shoot of per plant for each genotype. The statistical analysis method used was the same as Fig. 7. Values are average number of each genotype (arithmetic mean ±SD of n=5–7). Different letters indicate significant differences between the groups.
