BcSnods

Botrytis cinerea is a necrotrophic fungus that causes billions of dollars in agricultural damage every year.  The BcSnod virulence factors are proteins secreted in the early stages of infection.  Structure/function work on these virulence factors is underway along with characterization of their mechanism of action.  Related to the BcSnods is the search for natural product antifungals.
