Azorhizobium caulinodans

Azorhizobium caulinodans is a species of bacteria that forms a nitrogen-fixing symbiosis with plants of the genus Sesbania.[1] The symbiotic relationship between Sesbania rostrata and A. caulinodans lead to nitrogen fixing nodules in S. rostrata. Bacterial chemotaxis plays an important role in establishing this symbiotic relationship.[2]

Azorhizobium Caulinodans is a genome and it contains chemotaxis gene clusters that are unique. It has five chemotaxis genes which are: cheW(1), cheW, cheA, cheR, and cheB. Azorhizobium Caulinodans controls the movements of flagella, and the chemotaxis signaling path in Azorhizobium Caulinodans helps with regulating biofilm formation.[3]
