Legumes form a beneficial symbiosis with nitrogen-fixing bacteria called rhizobia, that leads to the formation of root nodules. We are interested in the molecular mechanisms controlling nodule development in legumes with the long-term aim of expanding nitrogen-fixing associations to reduce nitrogen fertiliser use. We are using a mixture of molecular, cell biological and chemical ecology approaches to understand what features are necessary and unique for nodulation in legumes and what makes the symbiosis functional under biotic stress from soil parasites and pathogens. One focus is on the role of root flavonoids in controlling nodule development and in the communication between roots and soil microbes.
