Table 2 Gene expression levels of pri-miRNA targets in roots and leaves of A. thaliana plants. Nineteen-days-old plants were exposed for 24 or 72 h to 0.5 μM CuSO4, 5 μM CdSO4 or grown under control conditions. Transcript levels were calculated relative to the non-exposed plants at each time point. Data are mean ± S.E. of 3 biological replicates. Significant differences (P < 0.05) relative to the non-exposed plants at each time point after one-way ANOVA test and Tukey correction are indicated in color (upregulation, green; downregulation, red)
