Non-metric multidimensional scaling (nMDS) of the RNA-Seq data – (A) based on KEGG transcripts; (B) CAZy transcripts and (C) Phyla abundances. KEGG and Phyla abundances are clustered by soil types [organic (O) vs. mineral (M)] and treatments [Heated (H) vs. Control (C); KEGG and Phyla] and CAZy transcripts are clustered by soil types, treatments, and time points (T2 and T6). Correlations with grouped samples were calculated by a three-factor multivariate PERMANOVA analyses based on Bray-Curtis similarity that revealed significant differences between soil types (organic vs. mineral) but no differences between time points (T2 vs. T6) or treatments (heated vs. control) in all three groups.
