FIG 5 .

The detected diversity in metagenomic data associated with individual pathways. Colors correspond to different pathways (acetyl-CoA pathway, orange; glutarate pathway, blue; 4-aminobutyrate pathway, pink; lysine pathway, grey). Bacterial names represent members of individual groups (based on 10% complete linkage clustering; for details, see Materials and Methods). Groups consist of the following: (i) only one reference genome (indicated by single strain names), (ii) merged strains of the same species (indicated by species name without strain information), and (iii) merged genomes from distinct species (individual names are given). The group “Fusobacteria several strains” consists of the following strains: Fusobacterium nucleatum subsp. nucleatum, Fusobacterium nucleatum subsp. polymorphum ATCC 10953, Fusobacterium periodonticum ATCC 33693, sp. 1_1_41FAA, sp. 11_3_2, sp. 2_1_31, sp. 21_1A, sp. 3_1_27, sp. 3_1_33, sp. 3_1_36A2, sp. 4_1_13, sp. 7_1, sp. D11, and sp. D12. For more information on taxon assignment, see Materials and Methods. The box plots display data distributions for each group of all 15 samples analyzed (A to O). The degree of explanation indicates the percentages of reads matching a group, which was included in diversity analysis (this figure). For more explanation, see the text.
