Query: NC_008380:4532969 Rhizobium leguminosarum bv. viciae 3841, complete genome

Lineage: Rhizobium leguminosarum; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This biovar nodulates legumes in the Tribe Viciae (Vicia, Pisum, Lathyrus, Lens). This strain is a spontaneous streptomycin-resistant mutant of strain 300. Nitrogen-fixing plant symbiont. This organism, like other Rhizobia, establishes a symbiotic relationship with a legume plant, providing nitrogen in exchange for a protected environment. The legume roots secrete flavonoids and isoflavonoids which the bacteria recognize and use to turn on genes involved in root nodulation. Many of the root nodulation genes are involved in synthesis and secretion of a nodule inducing signal, a lipochito-oligosaccharide molecule, which the plant recognizes, triggering nodule formation. The bacterium is endocytosed and exists inside a membrane bound organelle, the symbiosome, and fixes nitrogen for the plant cell while the host cell provides carbon compounds for the bacterium to grow on. The nitrogen fixation is important as it obviates the need for expensive and environmentally damaging fertilizer use.

Subject: NC_008343:823093 Granulibacter bethesdensis CGDNIH1, complete genome

Lineage: Granulibacter bethesdensis; Granulibacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria

General Information: Isolated from a patient with fever and lymphadenitis. Chronic granulomatous disease (CGD) is a rare inherited disease of the phagocyte NADPH oxidase system causing defective production of toxic oxygen metabolites, impaired bacterial and fungal killing, and recurrent life-threatening infections. This species was isolated from a 39 year old man with CGD and was shown to be the causal agent of the disease by classical methods. The isolation of this organism is the first known case of a bacterium from the Acetobacteraceae family to be the cause of an invasive human disease.
