Query: NC_016622:282631 Azospirillum lipoferum 4B, complete genome
Lineage: Azospirillum lipoferum; Azospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Azospirillum is a bacteria belonging to the order Rhodospirillales, associated with roots of monocots, including important crops, such as wheat, corn and rice. Azospirillum is the primary commercial phytostimulator inoculant for cereals worldwide. Azospirillum lipoferum 4B has been isolated from a rice field of Camargue (South of France) in 1982 and has been studied for its high efficiency in nitrogen fixation and for its successful properties of rice colonization and growth promotion.
Subject: NC_011420:3650724 Rhodospirillum centenum SW, complete genome
Lineage: Rhodospirillum centenum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Rhodospirillum centenum, also called Rhodocista centenaria, is a nitrogen-fixing photoheterotroph with a complex life cycle. R. centenum is one of the few known thermotolerant purple bacteria species with optimal growth temperature of 44 dgrees C and a maximal growth temperature of 48 degrees C. In liquid media this organism is motile by a single polar flagellum. R. centenum produces lateral flagella to become a swarming cell. Under low nutrient conditions R. centenum forms a desiccation- and UV-resistant cyst. R. centenum can often be cultivated from hot springs such as those found at Yellowstone National Park. R. centenum is emerging as a model organism for genetic and molecular genetic analysis of cyst formation.
