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.

Subject: NC_006370:768745 Photobacterium profundum SS9 chromosome 1, complete sequence

Lineage: Photobacterium profundum; Photobacterium; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria

General Information: Isolated at a depth of 2500 m from the Sulu Trough. High pressure tolerant bacterium. This bioluminescent genus was originally identified in 1878 in association with hake (a marine fish) in Cape Town, South Africa. This species was originally isolated from an amphipod homogenate enrichment from the Sulu Sea. It is a genetically tractable model system for studies of low temperature and high pressure adaptation, and has been used in studies of mono- and polyunsaturated fatty acid production under these conditions.
