FIGURE 2.

Whole-genome phylogeny of established Bcc species, taxon K strains and related Other Bcc group isolates. bcgTree was used to extract the amino acid sequences of 107 single-copy core genes from the genomes of 61 Burkholderia strains and to reconstruct their phylogeny through partitioned maximum-likelihood analysis (Ankenbrand and Keller, 2016). The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) are shown next to the branches if greater than 50%. The scale bar indicates the number of amino acid substitutions per site. Species names on the branches correspond to the taxonomic proposals in the present study, previous nomenclature is indicated next to braces on the right. Bold font indicates type strains of established Bcc species. Strains that were reclassified into the novel species Burkholderia aenigmatica sp. nov. are marked in blue.
