Research interest

Plant diseases affect plant yield and quality, and have caused serious agricultural economic losses. The goal of our laboratory is to study the molecular mechanisms of plant pathogenic bacteria, and plant resistance to diseases, especially the immune pathways triggered by pathogenic effectors.
