Novel Microbial Killer Protein Against Fusarium Plant Pathogens

Dr. Vladimir Vujanovic at the University of Saskatchewan has discovered novel microbial killer proteins isolated and characterized from Sphaerodes mycoparasitica (Vujanovic and Goh, 2009) isolate (IDAC 301008-01), which biotrophicaly parasitize Fusarium avenaceum and F. graminearum  plant pathogenic isolates, causing lethal changes in Fusarium’s cell functioning and inducing programmed cell death. The Fusarium disease control effect of the mycoparasite has been confirmed in greenhouse testing and field trials. Novel alternatives for Fusarium disease control could be developed based on the proteins isolated from the mycoparasitic fungal and the mycoparasitic fungal itself.
