The effects of the overexpression of EpTDC1 and EpASMT on heavy metal-induced tolerance in Arabidopsis thaliana. Seeds of the transgenic EpTDC1 (EpTDC1–1/EpTDC1–2) and EpASMT1 (EpASMT1–1/EpASMT1–2) A. thaliana grown on 1/2 strength Murashige-Skoog (MS) medium plates contained 0, 5.0, and 10.0 μM Cd2+, and 0, 10.0, and 30.0 μM Cu2+ respectively for 10 d. The wild-type (WT) A. thaliana was used as control. Photographs showing the growth of A. thaliana in Cd and Cu concentrations, respectively (A, D) (scale bars = 1 cm). Meanwhile, the root length (B, E) and fresh weight (C, F) were measured. Data are means ± SD (n = 6). Columns with different letters denote significant differences at P < 0.05 according to Duncan’s multiple range test
