Phylogenetic tree highlighting the position of P. inhibens relative to the type strains of the other species within the genus Phaeobacter and the neighboring genera Leisingera and Ruegeria [1,20–33]. The tree was inferred from 1,385 aligned characters [34,35] of the 16S rRNA gene sequence under the maximum likelihood (ML) criterion . Rooting was done initially using the midpoint method  and then checked for its agreement with the current classification (Table 1). The branches are scaled in terms of the expected number of substitutions per site. Numbers adjacent to the branches are support values from 1,000 ML bootstrap replicates  (left) and from 1,000 maximum-parsimony 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’ with two asterisks . The genomes of six more Leisingera and Phaeobacter species are published in the current issue of Standard in Genomic Science [41–46]. The 16S rRNA sequences of P. inhibens strain DSM 24588 and P. inhibens strain DSM 17395 are virtually identical to those of P. inhibens DSM 16374T (data not shown).
