Plant viruses are a major limiting factor for crop production worldwide. Viral diseases can cause yield losses up to 100%. Natural plant resistance genes provide non-chemical options in controlling plant viruses, reducing the amount of pesticide inputs to crops. As a member of the Plant-Virus Interactions Group, my research focusses on the identification and characterisation of plant resistance genes to Turnip mosaic virus (TuMV) and Turnip yellow virus (TuYV) in Brassica species. In particular, I am interested in the molecular mechanisms underlying TuMV andTuYV infections and how viruses can overcome resistance, with the aim of developing durable resistance for plant breeding.
