1223 | CoFe2O4 | an antioxidant cobalt ferrite (CoFe2O4) nanozyme as a bridge between nanotechnology and biological nitrogen fixation, which was shown to efficiently regulate the reactive oxygen metabolism and protect nitrogenase, thereby significantly enhancing the symbiotic nitrogen fixation efficiency by 260% in Glycine max (L.) Merr. (soybean). The CoFe2O4 nanozyme was also revealed to effectively reduce the concentration of ROS in the nodule by 56.6%, creating a superior environment for the proliferation of rhizobia and forming more effective nodules (larger nodules for an increase of 45.6% in the number of parasitic rhizobia). Furthermore, the CoFe2O4 nanozyme was shown to act as a synergist of leghemoglobin and increase its accumulation by 45.9%, where the high concentration of leghemoglobin in nodular cells can create a relatively hypoxic environment and protect nitrogenase, thus achieving a quantitative leap in nitrogen fixation capacity and simultaneously increasing the soybean photosynthesis by 67.2%. Our study has demonstrated that the CoFe2O4 nanozyme can efficiently regulate the intracellular ROS metabolism and serve as a promising strategy for enhancing symbiotic nitrogen fixation. | ROS | |||||||
