Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium forms an endosymbiotic nitrogen fixing association with roots of legumes. The bacteria colonize plant cells within root nodules. Here the bacteria converts atmospheric nitrogen to ammonia and then provides organic nitrogenous compounds such as glutamine or ureides to the plant. The plant provides the bacteria organic compounds made by photosynthesis.[1]
