Group Leader
Ray investigates the process of nitrogen fixation in free-living bacteria, how this is regulated and how to use this knowledge to enhance agricultural productivity.
He is investigating the minimal set of bacterial nitrogen fixation genes that can be expressed in a plant to produce active nitrogenase.
Ray is also interested in understanding the genetic regulation of nitrogen fixation in plant associated bacteria, in order to stimulate release of fixed nitrogen that can be assimilated by cereal crops.
- Genetic regulation of nitrogen fixation
- Understanding the signalling pathways which regulate nitrogen fixation genes
- Enhancing agricultural productivity through nitrogen fixation
