Phylogenetic tree highlighting the position of H. baltica relative to the type strains of the other species within the family Hyphomonadaceae. The tree was inferred from 1,332 aligned characters [6,7] of the 16S rRNA gene sequence under the maximum likelihood (ML) criterion  and rooted with the neighboring family Parvularculaceae. The branches are scaled in terms of the expected number of substitutions per site. Numbers adjacent to the branches are support values from 450 ML bootstrap replicates  (left) and from 1,000 maximum parsimony (MP) bootstrap replicates  (right) if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD  are labeled with one asterisk, those also listed as ‘Complete and Published’ (as well as the target genome) with two asterisks [12,13].
