In leguminous plants, the root nodules are homes for a group of nitrogen-fixing bacteria called?

The group of nitrogen-fixing bacteria that live in root nodules of leguminous plants is called Rhizobium. Inside the root nodules, Rhizobium bacteria convert atmospheric nitrogen into a form that the plant can use, through the process of nitrogen fixation. This process provides the plant with a critical source of nitrogen for growth and development. Rhizobium is an essential part of the nitrogen cycle in the ecosystem and plays a vital role in maintaining soil fertility.
