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_018664:1 Clostridium acidurici 9a chromosome, complete genome

Lineage: Gottschalkia acidurici; Gottschalkia; ; Clostridiales; Firmicutes; Bacteria

General Information: Clostridium acidiurici is an obligate anaerobic Gram-positive bacterium that is motile and spore-forming. It can be isolated from almost every soil but can also be found in the intestinal tract of birds. It is able to use purines like uric acid as sole carbon, nitrogen and energy source to build ammonia, carbon dioxide and acetic acid. Unlike most other Clostridia it is a specialist and not able to grow on sugars or different other substrates than purines.
