Azorhizobium is a genus of Gram-negative soil bacteria. They fix nitrogen in symbiosis with plants in the genus Sesbania. Strain ORS571 of A. caulinodans has been fully sequenced.^[2]

Azorhizobium caulinodans ORS571 has exceptional properties because it is able to fix nitrogen in both aerobic free-living and symbiotic states ^[3]

Azorhizobium caulinodans ORS571 is a rice and wheat endophyte, and does not need plant metabolites to make functional nitrogenase, but low nitrogenase expression is observed when it is living in cereal roots.^[3]
