a Type IV pilus operon is highly conserved in TM7 genomes, but missing many components in genomes of the tongue-associated clade T1. Type IV pili operons from 52 of the 55 TM7 that included pilC are aligned according to pilC (yellow). Genomes are organized according to their phylogenetic organization shown in Fig. 5. The top 10 functions identified in these operons appear with color filling, while the rest of the functions appear in gray. Contig breaks are marked with red lines for contigs that include less than 9 genes either upstream or downstream from pilC. b Some phage groups span phylogenetic clades, while other phage groups associate with specific clades. At the top of the panel, the two prophages of phage group pg08 are compared and on the bottom of the panel the two prophages of the phage group pg02 are compared. White arrows signify genes as identified by Prodigal. Homologous genes, identified as belonging to the same GC, are connected by colored areas. A function name assigned by KEGG, COG, or Pfam functional annotation source appears for genes for which it was available. On the left, the phylogenetic clade of the TM7 host of each prophage is listed next to the host genome name. The genome-wide average nucleotide identity (gANI) appears for each pair of the host genomes, where C/I stands for alignment coverage/alignment identity
