Figure 2From: Comparative genomics reveals evidence of marine adaptation in Salinispora speciesNADH dehydrogenase-related gene phylogenies. Representative phylogenies for (A) the NDH-1 partial 2 operon (NuoM) and (B) the NDH-1 partial 3 operon (MrpD). Branch colors: orange = Actinobacteria, red = Proteobacteria, brown = Firmicutes, green = Chlorbi, Pink = Cyanobacteria, gray = Deinococus-Thermus, and black = other bacterial phyla. Names of marine bacteria are colored blue and non-marine black. Midpoint rooting was used and likelihood values shown for each node. Scale bar represents changes per site. See Additional file 4 for detailed tree parameters. The NuoL homolog from S. tropica was used as an outgroup in the MrpD tree but is not shown.Back to article page
