Taxonomic and functional repertoire of the GKGMC. a, phylogenetic analysis of 1002 microbial genomes. Labels show prevalent genome names, and are chosen to be informative but not overlapped. b. the phylogenetic tree of GKGMC enriched microbial taxa, including F082, Ruminococcus_E, Sodaliphilus, Treponema, and archaea. Nodes represent MAGs from the GKGMC, and other homologous strains are retrieved from the NCBI genomes (additional file 1). c, Heatmap showing counts of polysaccharide-degrading CAZymes, as well as polysaccharide utilizing loci (PULs) encoded in each MAG. d, circles representing the absence/presence of known MGC pathways in each genus. Larger circles indicate cases in which more than 50% of the genomes for a genus encode the pathway, whereas smaller circles indicate cases in which 50% or fewer of the genomes encode it. Colored ranges indicate a categorization of MGCs by chemical class of their product.
