Query: NC_009485:7827782 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_010682:3313944 Ralstonia pickettii 12J chromosome 1, complete sequence
Lineage: Ralstonia pickettii; Ralstonia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Ralstonia pickettii 12J was isolated from copper-contaminated sediment from a lake in Michigan, USA. In addition to being highly resistant to copper, strain 12J is also resistant to zinc and cadmium. Ralstonia pickettii can be isolated from a wide range of environmental and clinical samples. This species is a nocosomial pathogen. It is associated with infections caused by contaminated solutions, such as distilled water and intravenous solutions. Ralstonia pickettii strains resistant to heavy metals have also been isolated from heavy metal contaminated environments.
