Program Description
Research in this area includes studies that address mycotoxin biosynthesis in vivo or in planta, host/parasite interactions, and host resistance mechanisms that target the pathogen. Research in PBG should complement and be linked to whole plant research that will lead to disease control and/or toxin reduction strategies.
FY20-21 Research Priorities Derived from Action Plan Goals:
- Characterize plant-fungal interactions to identify important genes, proteins or small molecules that may be used to develop FHB resistance or to reduce DON contamination in barley and wheat.
- Gain new understanding of initial fungal infection that may be utilized to boost FHB resistance.
- Discover epiphytic or endophytic microbes or microbial communities and viruses that may be useful for development of effective biological control practices for FHB.
- Develop an improved understanding of plant-pathogen interactions in relation to abiotic factors and identify genes or genetic variants that contribute to pathogen adaptation to wheat and barley agroecosystems.
