RT-PCR results of BpCOMT and PtCOMT in silver birch roots. Relative expression of the endogenous putative caffeate/5-hydroxyferulate O-methyltransferase of silver birch (BpCOMT) (A) and the heterologous PtCOMT gene (B) normalized using atub and putative BpPP2A as reference genes in the non-inoculated and mycorrhizal roots of clone A and PtCOMT-modified lines 23, 44 and 65. Values are means ± standard error. Different letters above the columns denote significant (P < 0.05) difference between the PtCOMT lines and clone A within the treatments according to the two-sample t-test or the Wilcoxon rank sum test with the Bonferroni correction. Number of replicates 3-5.
