Query: NC_008043:167108 Silicibacter sp. TM1040 mega plasmid, complete sequence Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.

General Information: This strain is a derivative strain isolated in the laboratory of Barry Marrs from the classical progenitor strain B10. It is rifampicin-resistant, produces GTA, and is capable of growing under high illumination (resistant to photooxidative killing). Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to use photosynthesis and usually can grow under both anaerobic and aerobic conditions. This organism is a facultatively phototrophic purple non-sulfur bacterium and the type species of the Rhodobacter group. The colony's color depends largely on the amount of oxygen present in its environment. While it is able to produce cellular energy in a number of different ways, it can rely on anoxygenic photosynthesis under anaerobic conditions in the presence of light. Some strains produce the Gene Transfer Element (GTA), a pro-phage particle capable of transferring genetic material between strains.
