Develop a rapid and efficient whole-plant system that allows potentially useful transgenes to be assessed for efficacy against FHB before they are introduced into wheat or barley.
Approach: Establish Physcomitrella patens as a pathosystem for studying infection by F. graminearum. Compare the efficacy of different plant transgenes against FHB in Physcomitrella. Determine the efficacy of wheat and barley genes encoding BI-1 and L3Delta to confer resistance to DON and FHB in Physcomitrella.
