Scientific Activities

The genome sequencing of Blumeria graminis, the fungus that causes powdery mildews in cereals, was a landmark on the road to understanding obligate biotrophic interactions between plants and fungi. One of the most significant discoveries was the importance of a superfamily of genes encoding effector-like proteins. The most prominent group of these includes proteins which resemble ribonucleases: the RibonucleAse-Like Proteins expressed in Haustoria (RALPH) effectors . My research now focusses on understanding the mechanisms that underpin the activity of the RALPH effectors, and what makes these essential for the display of full virulence in the cereal powdery mildews.
