Research interests

Legumes form symbiotic interactions with rhizobial bacteria that lead to the formation of nodules on the roots of the host plant. The bacteria reside inside the cells within the nodule and convert molecular dinitrogen (atmospheric nitrogen) to ammonia, a form of nitrogen readily available to the plant. The initial stages of this interaction involve molecular communication between the plant and the bacteria. Nod factor is a critical signalling molecule generated by the bacteria that activates key responses in the plant. The work in this laboratory looks at a number of aspects of the legume/rhizobial symbiosis with a focus on Nod factor perception and signal transduction in the plant. We work on the model legume Medicago truncatula which interacts with the rhizobial species Sinorhizobium meliloti.
