Fig 3. Whole-genome GBDP phylogeny (based on the nucleotide data).

Bootstrap values over 60% are shown at each node. An assignment to genomic species was based on the distance threshold equivalent to 70% dDDH (dDDH ≥ 70% indicates same genomic species) and dDDH < 70% (indicates distinct genomic species). Genomic species groups are marked by numbers whereas genomic subspecies groups are denoted by letters. The orange box indicates the outlying Thioalkalivibrio strains, contesting the monophyly of the genus.
