4. Research Description:
Our lab is interested in studying how Chinese wild grapes sense and respond to Plasmopara viticola stress. Particularly, we are interested in understanding regulation of disease resistant signaling mechanisms and disease resistance genes under P. viticola stress in Chinese wild Vitis species. Our research involves analysis of function of target genes with bio-chemical method in vitro, and also genetic and molecular characterization of grapevine that are altered in response to the pathogen stimuli. The goals are to elucidate the Chinese wild grape signaling pathways in response to the pathogen stress and to identify key components that can potentially be engineered for improvement of crop plants to encounter pathogen stress. His research program focuses on developing new variety with resistance to fungi diseases, such as Downy mildew. His lab studies the genetics of resistance to this fungal disease, their genetic diversity and aggressivity, and host/pathogen interactions of this fungal with Chinese wild grape species. Dr. Xu's lab is also actively involved in breeding table, raisin grapes for resistance to Downy mildew. Particularly, we are interested in breeding of seedless grape variety for resistance to Downy mildew with cross combinations between Chinese wild grapes species and commercial seedless grape varieties using embryo rescue method.
