From: Phenolic compounds in ectomycorrhizal interaction of lignin modified silver birch
The lignin syringyl/quiaicyl ratios of non-inoculated and mycorrhizal silver birches. The lignin syringyl/quiaicyl (S/G) ratios of stems (A) and roots (B) of non-transgenic clone A and PtCOMT-modified lines 23, 44 and 65. Values are means ± standard deviation. Different letters above the columns denote significant (P < 0.05) differences between the non-inoculated and mycorrhizal plants within the line/clone and between lines/clone within the fungal treatment according to the Wilcoxon rank sum test with the Benjamini & Hochberg correction or the two-sample t-test with the Benjamini & Hochberg correction. Number of replicates 3.
