Figure 2: Phylogenetic affiliation of A. borkumensis SK2 based on 16S rDNA sequence comparison.
From: Genome sequence of the ubiquitous hydrocarbon-degrading marine bacterium Alcanivorax borkumensis

Neighborhood-joining tree showing a 16S rDNA gene phylogeny-based placement of A. borkumensis among the γ-Proteobacteria. Sequences were taken from the type strains of the given organisms. Marine organisms with completely sequenced genomes are highlighted in bold. The tree is rooted with Aquifex pyrophilus M83548. The α-proteobacterial strain Silicibacter pomeroyi served as outgroup.
