Fig. 6 — Analysis of Zn (a) and Cd (b) in leaves, stems and roots of poplar plants, WT and ScZRC1-expressing plants. Metals were analyzed after 3 weeks of growth in mesocosmos pots filled with soil artificially contaminated with 10 mg kg⁻¹ CdSO₄ and 300 mg kg⁻¹ ZnSO₄. Different letters above the histograms indicate statistical significance, evaluated by one-way ANOVA followed by a post hoc Tukey’s test (P < 0.05, n = 5)
