Query: NC_009485:1487485 Bradyrhizobium sp. BTAi1 chromosome, complete genome Lineage: Bradyrhizobium; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria General Information: This organism is a photosynthetic rhizobium that is also capable of nitrogen-fixation, the first such example of such an organism. It can form nodules on the legume Aeschynomene indica and was isolated from this plant at the Boyce Thompson Institute for Plant Research in Ithaca, NY. It can form stem and root nodules. The photosynthetic reaction centers are similar to those found in purple photosynthetic bacteria and this microbe aids the plant in carbon metabolism and nitrogen metabolism.

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.
