Biography

Biography: 

Shunyuan Xiao is a professor of the Institute for Bioscience and Biotechnology Research (IBBR) and the Department of Plant Sciences and Landscape Architecture, University of Maryland College Park. He received his Bachelor’s, Master’s and Doctoral degrees in Plant Genetics from Huazhong Agricultural University, China. After postdoctoral research at University of Florida, USA and University East Anglia, UK, he became an assistant professor of the University of Maryland Biotechnology Institute in 2003 and joined the University of Maryland College Park as an associate professor in 2010. Dr. Xiao’s research interest is focused on elucidating the molecular mechanisms of plant resistance against fungal pathogens and engineering novel resistance.

Research

Areas of Interest: 

  • Plant immunity

  • Powdery mildew pathogenesis

Current research in the Xiao Lab aims to understand molecular mechanisms of plant immunity against adapted and non-adapted pathogens using the plant-powdery mildew interaction pathosystem.  Areas of research interests 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.
