Query: NC_009485:1648896 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_010688:1908012 Xanthomonas campestris pv. campestris, complete genome
Lineage: Xanthomonas campestris; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This genus consists of plant-specific yellow-pigmented microbes, some of which are economically important phytopathogens that devastate crops such as citrus plants, rice, beans, grape, and cotton. These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. This species is a major cause of black rot in crucifers, a disease that results in massive tissue degeneration. It also produces an extracellular polysaccharide known as xanthan, which is harvested commercially as a food stabilizing agent for use in industry.
