Query: NC_009485:8138314 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.
Subject: NC_007643:955362 Rhodospirillum rubrum ATCC 11170, complete genome
Lineage: Rhodospirillum rubrum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: This bacterium can grow using carbon monoxide as the sole carbon and energy source and the cells contain a well characterized nitrogenase system that is post-translationally modified by ADP-ribosylation. Phototrophic bacterium. This organism is an anoxygenic phototrophic bacterium that does not produce oxygen, but instead produces extracellular elemental sulfur when harvesting light energy. The bacterium lacks the light harvesting complex 2 (LHC2) normally found in photosynthetic bacteria meaning it contains one of the simplest photosynthetic systems studied.
