My research centers around plant parasitic nematodes and primarily focuses on root-knot nematodes and their interactions with host plants. These small roundworms are soil borne pathogens with a broad host range. They infect plant roots and can cause damage that affects water and nutrient uptake. As a result, root-knot nematodes cause billions of dollars in crop losses each year. In order to develop new strategies to combat nematodes, my group studies the genetic components of the nematode that allow it to manipulate plant signaling pathways and successfully infect plants. One focus of study is on the root-knot nematode Meloidogyne chitwoodi, a serious pathogen of potatoes in the region. We are interested in identifying novel M. chitwoodi pathogenicity genes required for successful potato infection and in dissecting the defence responses triggered during infection of resistant potato. My lab uses a variety of experimental approaches, such as gene expression analyses, generation and characterization of transgenic plants, and heterologous expression of nematode genes in bacteria, to increase our knowledge of the plant/nematode interaction at the molecular level.
