study guides for every class that actually explain what's on your next test Rhizobia
from class: Microbiology Definition 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.

Predict what's on your test 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. Review Questions What role do rhizobia play in nitrogen fixation? Where do rhizobia typically form symbiotic relationships? Which enzyme is crucial for the nitrogen-fixing process in rhizobia?
