From: Toxicity responses of Cu and Cd: the involvement of miRNAs and the transcription factor SPL7
The translocation factor of copper and cadmium from root to leaves. Nineteen-days-old A. thaliana wildtype and spl7 knockout plants were exposed for 24 or 72 h to 2 μM CuSO4, 5 μM CdSO4 or grown under control conditions. The translocation factor (TF) of Cu (a) and Cd (b) were calculated as the percentage of the concentration in the leaves relative to the concentration in the roots. Data are given as the mean ± S.E. of 5 biological independent replicates. Significant differences (P < 0.05) after non-parametrical ANOVA test (Kruskal-Wallis) and correction with pairwise Wilcoxon rank sum test are indicated as following: treatment difference with an asterisk (*) and genotype difference with connection lines
