Figure 5

Effect of metal treatments on root growth and shoot fresh weight in transgenic lines. Photographs of Camelina wild-type and two CsHMA3-overexpressing lines grown on agar plates containing different concentrations of Cd, Pb, and Zn stress for one week (A). Root growth rate (B) and fresh weight (C) of the plants were measured at the seventh day after heavy metal treatment. For the Pb treatment, we used control medium without phosphate. Data represent means ± SD (n = 30). Asterisks in the figure indicate significant difference from wild type at *P < 0.05, **P < 0.01, and ***P < 0.001 by Dunnett’s test.
