MAGs cover most of the abundant genera of the oral microbiome as well as represent lineages absent in public genomic databases. The dendrogram in the middle of the figure organizes 227 MAGs, 1582 genomes from the HOMD, and a single archeon, which was used to root the tree, according to their phylogenomic organization based on our collection of ribosomal proteins. The bars in the innermost circular layer represent the length of each genome. The second layer shows the phylum affiliation of each genome. The third layer shows the 10 most abundant genera in our samples as estimated by KrakenUniq. The fourth layer shows the affiliation of genomes as either MAGs from our study (blue) or genomes from HOMD (gray). The outermost layer marks novel genomes of lineages that lack representation in HOMD and NCBI. The lowest taxonomic level that could be assigned using CheckM and sequence search (see “Material and methods”) is listed for each novel lineage
