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.
Current projects include:
- Flux control in N-fixing rhizobia (in collaboration with Prof George Ratcliffe and Dr Nick Kruger, University of Oxford)
- Role of the FixABCX complex in electron allocation to nitrogenase (in collaboration with Dr Nick Watmough, University of East Anglia)
