Fresh weight in leaves and roots of A. thaliana wildtype and spl7 knockout plants. Nineteen-days-old plants were exposed for 24 h or 72 h to 2 μM CuSO4, 5 μM CdSO4 or grown under control conditions. Data of the leaves (upper bars) and roots (lower bars) are given as the mean ± S.E. of 5 biological independent replicates. Significant differences (P < 0.05) after three-way ANOVA test and Tukey correction are indicated as following: treatment difference with an asterisk (*), time difference with a tilde (~) and genotype difference with connection lines
