What Does Rhizobium Do?

Rhizobium spp. are soil-dwelling α-Proteobacteria that can fix nitrogen in a symbiotic relationship with leguminous plants. Nodules develop on the roots of nitrogen-starved legumes such as peas, beans, clover, and soy.

What is the function of Rhizobium?

The basic function of rhizobium is fixing atmospheric Nitrogen for the plants to provide them with nitrogenous compounds and establishes a symbiotic relationship with the plants as explained above.

How does Rhizobium fix nitrogen?

Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.
