Research Area

Research in my laboratory is aimed at a better understanding of how viruses interact with each other and with their hosts when plants are multiply infected. Work on related viruses (cucumber mosaic virus, citrus tristeza virus) includes an analysis of the genetic diversity within isolates, and cross protection studies. Satellite tobacco mosaic virus (STMV) is a virus that depends on tobacco mosaic virus to replicate and has become a model system for studying the molecular biology and genetics of sub-viral parasites. Interactions between the movement protein of one virus and the infection cycle of additional unrelated viruses has also been investigated, leading to the interesting observation that a functional movement protein of one virus can enhance disease expression of unrelated viruses, but a dysfunctional analog can act as a resistance gene. Development of nucleic acid based detection methods for plant viruses is another ongoing project, in part because they are required for research on mixed virus infections.
