Subject: NC_008702:369965 Azoarcus sp. BH72, complete genome
Lineage: Azoarcus; Azoarcus; Rhodocyclaceae; Rhodocyclales; Proteobacteria; Bacteria
General Information: This organism is a nitrogen-fixing obligate endophyte first isolated from the roots of Kaller grass in the Punjab region of Pakistan. These organisms are never found in root-free soil and colonize root tissues without causing disease. This strain has been shown to express genes involved in nitrogen fixation in root tissue and is thought to provide significant amounts of nitrogen to its host plant.
