This is the "Fungal Pathogenetics" laboratory. Our laboratory focuses on obtaining knowledge on the basic biology and molecular genetics of insect pathogenic fungi so that they might be used more effectively for biocontrol. There are currently three major Research Foci in the lab:
(1) Genetic analysis of fungal pathogenesis
We examine virulence factors primarily in insect pathogenic fungi. We use a variety of molecular (gene knockout) and biochemical approaches to identify genes involved in insect pathogenesis. On another level we are interested in broader questions of fungal pathogenesis of plants, insects and humans. Why are some fungi pathogens while others are saprophytes? What allows some fungi to infect insects but not plants and vice versa?
(2) Population genetics of insect pathogenic fungi
We use allozyme analysis and genetic polymorphismat various loci to examine the population structure and phylogeny of insect pathogenic fungi. We are also looking at comparative population genetics to determine if pathogenic fungi have different genetic structures depending on whether they are obligate, facultative or opportunistic pathogens.
(3) Genetics of conidiation
We are attempting to elucidate the genes involved in conidiation in insect pathogenic fungi. We are also looking at a phenomenon termed "pleiomorphic deterioration". This occurs when fungi that are continuously subcultured lose the ability to produce conidia. This problem has been observed in several other industrially important fungi.
