Real-time RT-PCR analysis on the expression of poplar transporters PaMTP1 (a), PaNRAMP1.3 (b), PaPCR2 (c) and PaHMA4 (d) in leaves of wild type and ScZRC1-expressing plants, exposed to high Zn and Cd in comparison to control conditions. The expression levels were calculated using the 2−ΔΔCT method, relative to the expression level in leaves from WT plants upon untreated conditions. Different letters indicate statistical significance, evaluated by two-way ANOVA followed by a post hoc Bonferroni test (P < 0.05, n = 3)
