Comparative Genomic Analysis of Rhodococcus equi: An Insight into Genomic Diversity and Genome Evolution

Figure 3

Plot of the two first axes of the PCoA made from 796 ML trees. The other 33 genes are excluded due to the limit of axis demarcation. The ellipse depicts 562 orthologs in the densest region (stable core region) of the cloud that share a common phylogenetic signal, whereas trees present in the marginal area (the shell) are much more likely to be perturbed by horizontal transfers. The genes are color-coded based on its association to biological pathways.
