Abstract: We present the genome sequence of the octocoral-associated Roseobacter sp. EG26. We highlight features related to type II, III, IV, and VI secretion systems, ankyrin-repeat proteins, and taurine degradation, suggesting a preference for a host-associated lifestyle. Strain EG26 also possesses genes for the degradation of phenolic compounds with bioremediation potential.
