Table 4 Gene expression levels of pri-miRNAs in A. thaliana wildtype and spl7 knockout plants. Nineteen-days-old plants were exposed for 24 h to 2 μM CuSO4, 5 μM CdSO4 or grown under control conditions. Data of the genotype effect of the spl7 mutant are given as the fold changes ± S.E. of at least 3 biological independent replicates relative to WT plants (set at 1.00). Data of the treatment effect within each genotype are mean ± S.E. of at least 3 biological replicates relative to its own control (set at 1.00). Significant differences (P < 0.05) after one-way (genotype effect) or two-way (treatment effect) ANOVA test and Tukey correction are indicated in color (upregulation, green; downregulation, red). (ND, not detected after 40 cycli)
