Which organism is a nitrogen-fixing symbiont of legumes?

Question

Quizplus · Accepted Answer

Rhizobium is a genus of bacteria that are capable of forming a symbiotic relationship with legumes. They form nodules on the roots of legumes and can fix atmospheric nitrogen, converting it into a form that the plant can use for growth. This mutualistic relationship is important for both the bacteria and the plant, as it provides the plant with a source of nitrogen while the bacteria receive carbohydrates from the plant. Clostridium and Pseudomonas are not typically associated with nitrogen fixation, and Nitrobacter is involved in nitrification rather than nitrogen fixation.
