Rhizobia form a mutualistic association with legumes, wherein the rhizobia bacteria fix atmospheric nitrogen and convert it into a form that the plant can use for growth, while the legume plant provides the bacteria with carbohydrates and a suitable environment for growth. Agrobacteria are important plant pathogens, while E. coli is a commensal bacterium found in the gut of humans and other animals. Morels and truffles are fungi that form mycorrhizal associations with plants.
