Query: NC_017249:7917586 Bradyrhizobium japonicum USDA 6, complete genome

Lineage: Bradyrhizobium japonicum; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This nitrogen-fixing bacterium develops a symbiotic relationship with the soybean plant Glycine max and is related to other N2-fixing Rhizobia which are symbiotic with legumes. The bacterium establishes itself in a root nodule which provides a protective environment for the organism to live while the bacterium provides the plant cell with nitrogen. This is an agriculturally important symbiotic relationship as it obviates the need for expensive and environmentally damaging fertilizer.Genes that code for proteins involved in root nodulation are carried on the chromosome. The production of the nodulation signal, lipochitin, is directed by genes which are turned on in the presence of plant flavonoid compounds. The bacteria are endocytosed into a cortical cell, and are enclosed within a membrane bound organelle termed the symbiosome.

Subject: NC_012808:1122341 Methylobacterium extorquens AM1, complete genome

Lineage: Methylobacterium extorquens; Methylobacterium; Methylobacteriaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: First isolated in 1960 in Oxford, England, as an airborne contaminant growing on methylamine. This strain can grow on methylamine or methanol, but not methane. This organism is capable of growth on one-carbon compounds such as methanol. Methanol is oxidized to formaldehyde which is then used metabolically to generate either energy or biomass. These bacteria are commonly found in the environment, especially associated with plants which produce methanol when metabolizing pectin during cell wall synthesis. At least 25 genes are required for this complex process of converting methanol to formaldehyde and this specialized metabolic pathway is of great interest.
