Area of Expertise: Fungal Biology - Characterization of infection-related signaling pathways and genes important for fungal-plant interactions in Magnaporthe grisea and Fusarium graminearum

 

Dr. Xu also serves as Director of the Purdue-NWAFU Joint Research Center on plant biotic and abiotic stresses, Northwest Agriculture and Forestry University, No. 3 Taicheng Road, Yangling, Shaanxi, 712100, P.R. China.

Fungi have enormous impact on human welfare by destroying valuable crops and producing toxins that are harmful to humans and livestock. My interest lies in using genetic and genomics approaches to identify genes essential for fungal development and pathogenesis. My lab works with the rice blast fungus Magnaporthe oryzae and the wheat scab fungus Fusarium graminearum. Rice blast is one of the most severe diseases on rice and is a model to study fungal-plant interactions. Current efforts are focused on the signal transduction pathways regulating infection-related morphogenesis and infectious growth. We are also using proteomics and functional genomics approaches to identify pathogenesis-related genes and characterize their interactions during plant infection.

The wheat scab fungus is a less studied but important pathogen that has caused devastating epidemics recently in the US. Besides yield loss, F. graminearum also produced a variety of mycotoxins, including vomitoxin and zearalenone. Currently, we are using comparative genomics approaches to study genes that are important for F. graminearum biology and pathogenesis (in comparison with F. orysporum and F. verticillioides).  We are also studying molecular mechanisms regulating Fusarium-wheat interactions and DON production in flowering wheat heads.
