Quantitative real-time PCR analysis of genes involved in heavy metal transport (HvHMT1, HvHMT2, HvHMT3 and HvHMT4), ABA biosynthesis (HvZEP1, HvZEP2, HvNCED1, HvNCED2, HvAO1, HvAO2 and HvAO3) and ABA catabolism (HvABA8OH-1, HvABA8OH-2, HvABA8OH-3, HvBG1 and HvBG2) in non-irradiated (0- Gy) and irradiated (50- Gy) highland barley seedlings with 500 µM Pb(NO3)2 (a) and 75 µM CdCl2 (b) treatment. The results are reported as the relative expression of each gene transcripts with respect to internal standard. The relative value for the expression of each gene in non-irradiated sample was set as 1. Vertical bars represent the mean ± SD of three independent replications (n = 3). Significant difference between non-irradiated and irradiated sample for each gene is indicated with * at p < 0.05, ** at p < 0.01 and *** at p < 0.001, according to paired-sample t-test.
