Root nodules are useful for plants because they harbour nitrogen-fixing bacteria such as Rhizobium, Bradyrhizobium, Mesorhizobium and Sinorhizobium that fixes atmospheric nitrogen which is available to the plants. Root nodules are usually formed in leguminous plants. Root nodules are extra lobes of certain plants such as peas and beans in which nitrogen-fixing bacteria are found. Bacteria in these root nodules convert the atmospheric nitrogen into nitrates which the plants can utilise. The plants use this nitrogen to synthesise proteins and other materials.
