Research in my laboratory focuses on understanding the cell and molecular biology of resistance and pathogenesis to fungal caused vascular wilt diseases of plants. In particular, we are studying diseases caused by fungi of the genus Verticillium, which infect over 400 different crop plants worldwide and account for major crop loss in most countries. In Canada, substantial losses in potatoes, tomatoes, alfalfa and strawberries occur each year. We are using biotechnology to develop plant pathogen diagnostics and to genetically engineer more wilt-resistant cultivars by manipulating the expression of plant genes involved in host (eg. phenylalanine ammonia lyase, PAL) or resistance (eg. Verticillium-resistance, Ve).
