Rhizobia are a group of soil bacteria that form symbiotic relationships with leguminous plants. They fix atmospheric nitrogen into a form usable by the plant, aiding in protein synthesis.
5 Must Know Facts For Your Next Test
Rhizobia convert atmospheric nitrogen (N2) into ammonia (NH3) through nitrogen fixation.
They form root nodules on legumes where nitrogen fixation occurs.
The enzyme nitrogenase is essential for the nitrogen-fixing process and is found in rhizobia.
Rhizobia benefit from carbohydrates produced by the host plant through photosynthesis.
This symbiotic relationship significantly enhances soil fertility and reduces the need for chemical fertilizers.
