Comparison of P. gingivalis essential genes, core genome and the entire DEG. The red circle represents the distribution of the 463 P. gingivalis essential genes (determined using strain ATCC 33277), blue represents the distribution of the 1,476 gene P. gingivalis core genome and green represents the entirety of the 8,341 DEG curated genes. The innermost overlap shows genes found within all three datasets, while those found outside of all overlaps show genes specific to that individual dataset. Corresponding gene information can be found in Tables 1S and 3S.
