Thanks to nodule bacteria, legumes acquire the ability to absorb atmospheric nitrogen. The bacteria that cause the formation of nodules in legumes (nodule bacteria) belong to the genus rhizobium. These bacteria live freely in the soil, but molecular nitrogen can only be fixed in symbiosis with the plant. The plant-rhizobium complex is an example of true symbiosis. The plant provides bacteria with nutrients and creates optimal living conditions for them, and bacteria supply the plant with nitrogen for growth.
