The Xiao Laboratory at the Institute for Bioscience and Biotechnology Research aims to understand molecular mechanisms of plant immunity against adapted and non-adapted fungal pathogens using the plant-powdery mildew interaction pathosystem. Areas of research interest include (i) host immunity mediated by RPW8 at the extra-haustorial membrane (EHM)—the host-pathogen interface, (ii) EHM biogenesis and role in plant-fungal interaction, (iii) genetic / molecular basis of non-host resistance, and (iv) pathogenicity mechanisms of powdery mildew fungi.
