Fig. 4From: VBCG: 20 validated bacterial core genes for phylogenomic analysis with high fidelity and resolutionComparison between 16S rRNA gene tree (A) and the VBCG tree (B) of concatenated core genes. The tree of the VBCG genes were reconstructed using the concatenated 20 genes of each genome. The asterisk in the 16S rRNA gene tree indicates the main group of Escherichia species with pairwise identities > 99.0%Back to article page
