—GBDP phylogenomic analysis of the Variovorax whole-genome sequence data set. The branch lengths are scaled in terms of GBDP distance formula d₅. The numbers above branches are GBDP pseudo-bootstrap support values from 100 replications, with an average branch support of 80.6%. Leaf labels are further annotated by their genomic G + C content, genome sequence length, phenotypic attributes, and origin of isolation. The two Variovorax clades are indicated.
