Symbiotic Nitrogen Fixation Mechanism in Legumes

Release time:2021-12-20

    The root nodules of legumes have the ability of symbiotic nitrogen fixation, which is an environmentally friendly and efficient nitrogen use method in agricultural production. Symbiotic nitrogen fixation requires beneficial interaction between rhizobia and the plant host cells. To fix nitrogen, the plant needs to provide a low oxygen environment as bacterial nitrogenase is highly sensitive to oxygen.

    Through molecular genetics and proteomics, we are analyzing the molecular mechanism of the construction and maintenance of a microaerobic environment for symbiotic nitrogen fixation in legumes. In addition, we are committed to finding a low-oxygen environment similar to the nodule structure in other crops to maintain nitrogenase activity, and exploring ways to achieve nitrogen fixation in non-legumes.
