FIGURE 2.

The uptake and distribution of Cd in two Arabidopsis ecotypes. (A) Effects on dry weight under 10 μM CdCl₂ treatment. (B) Total Cd content in two ecotypes with or without 10 μM CdCl₂ treatment for 4 days. (C) Shoot and (D) Root mentals distribution. (E) Primary transport index of metals (shoot_{metal concentrations}/root_{metal concentrations}). Data are means of four measurements (n = 4), and the vertical bars indicate the SD. One (*) and two (**) asterisks indicate significant differences from the control at P < 0.05, and 0.01, respectively, ns, differences are not significant.
