Nitrogen fixation in legume nodules

As much as 50% of the biosphere’s available nitrogen (N) comes from biological nitrogen fixation (BNF) in legume nodules making it an essential process to life on earth. We work on the molecular mechanisms, including those of nutrient exchange within nodules to determine how plants regulate the carbon supply to bacteria and how bacteria control ammonia secretion to plants.
