Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes. To express genes for nitrogen fixation, rhizobia require a plant host; they cannot i

…atmosphere into bioavailable compound forms such as ammonia. Diazotrophs are typically microorganisms such as bacteria and archaea, with examples being rhizobia and Frankia and Azospirillum. All diazotrophs contain iron-molybdenum or iron-vanadium nitrogenase systems, and two of the most studied systems are…
