Pathogen Biology and Genetics (PBG)

PBG Research Area Committee Updated: 1/9/12
Chair, David Schmale, Virginia Tech
Vice-Chair, Ivan Rayment, University of Wisconsin
Linda Harris, Agriculture and Agri-Food Canada, Ottawa, ON
Jin-Rong Xu, Purdue University

Program Description

Research in this area includes studies that address pathogen diversity and mycotoxin biosynthesis on plants, 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.  Population surveys should be accompanied by studies of biological relevance.  Successive yearly surveys cannot be supported by this program, as funding is limited.

FY12-13 Research Priorities Derived from Action Plan Goals:

  1. Characterize plant-fungal interactions in plant lines being developed by researchers in the USWBSI.
  2. Develop new strategies for reducing impact of FHB disease and mycotoxin contamination in barley and wheat.  Focus on research that seeks to demonstrate a reduction in FHB or DON in planta.  Establish a protocol for transferring these new strategies into viable crop product through collaborative interactions with GDER.
