Rhizobium, Bradyrhizobium, Mesorhizobium, Sinorhizobium, and Azorhizobium-collectively known as rhizobia, are Gram-negative, nitrogen-fixing bacteria of agronomic importance because they perform nitrogen-fixing symbioses with leguminous plants (soybean, alfalfa, beans, peas, etc). The metabolism of amino acids like Glycine is indispensable for functioning of one-carbon metabolism and for the establishment of a fully effective, nitrogen-fixing root nodule symbiosis in M. loti
