qPCR expression analysis in leaves of selected genes identified in the SSH screen. Expression values were normalized to ScACTIN2 and represent means ± SE of six biological replicates after either 8 or 14 weeks of Zn + Cd treatment. Abbreviations of genes correspond to Supplementary Table S3. Significance levels were calculated with Student's t-test (*, p < 0.05; **, p < 0.01; ***, p < 0.001).
