Cd tolerance assessed in A. thaliana k.o. mutant cax3-1 at low Ca concentration. Comparison of Cd tolerance was performed between the A. thaliana wild type (WT; gray bars), cax1-1 (white bars), and cax3-1 (striped bars). Tolerance was assessed in vitro by measuring primary root length as a parameter for growth. One week after germination, plantlets were transferred at low (0.5 mm) Ca concentration in control condition or with 100 µm CdSO4 for another 1 week. Data are means ± sd (n = 15–27). *, P < 0.05 (Student’s t test).
