a, Phylogenetic trees of the 1,864 Stordalen Mire MAGs constructed using the GTDB 120 bacterial and 53 archaeal gene sets53, with the Patescibacteria and Micrarchaeota as outgroups, respectively. The inner multicoloured ring corresponds to phylum, with the Patescibacteria (in beige) indicated by an asterisk (*). The middle ring displays a bar chart of the number of polyphenol transformations encoded by each MAG (range 0–40). The outer rings indicate whether a given MAG expressed at least one polyphenol transformation in the palsa, bog or fen metatranscriptomes by the presence of a dot. Clades of ‘polyphenol talented’ genera are highlighted in red, polyphenol dominant genera are highlighted in yellow and genera that meet both definitions are highlighted in orange (bottom left legend). Numbering at clade tips corresponds to genus names in b. b, Plots showing the number of unique polyphenol transformation pathways expressed per genus in each habitat (left), and whether that genus contributed at least 10% of polymer, monomer or phenolic/benzoic acid transformations in any habitat (right). A dashed line at 15 expressed transformations delineates talented genera (Supplementary Fig. 10). Genera that are both talented and dominant are highlighted in orange.
