Absolutely (A, B) and tobacco-essential (C, D) pangenome maps. Absolutely essential (A, B) and tobacco-essential (C, D) genes were mapped to the P. gingivalis chromosome (A, C) and presented as gene presence-absence matrices (B, D). For the circular chromosomal mapping, (A, C), the P. gingivalis ATCC 33277 genome serves as the template for the overlay of the core gene sets (i.e. ubiquitously present across all 14 strains). For the gene presence-absence matrices (B, D), vertical blue lines indicate the presence of pangenome genes for each strain analyzed, whereas white vertical lines indicate gene absence.
