Project Description:

The Gene Discovery and Engineering Resistance (GDER) research area (RA) places its primary focus on understanding mechanisms of resistance to Fusarium head blight (FHB) and identification of wheat and barley gene variants that can be deployed to increase FHB resistance and/or reduce DON accumulation. The GDER RA also supports utilization of gene editing and transgenic strategies as methodologies to better understand resistance mechanisms with the goal to improve FHB resistance. However, GDER places priority on strategies that can be deployed without transgenesis; gene discovery and transformation of non-cereal systems will be supported only for the purpose of rapidly screening potential anti-Fusarium genes.

FY22 Research Priorities Derived from Action Plan Goals:

  1. Identify native and induced wheat and barley gene variants that improve FHB resistance and/or reduce DON accumulation.
  2. Develop assays that can be used to rapidly validate candidate wheat and barley genes for resistance or susceptibility to FHB and/or reduced DON accumulation.
  3. Utilize new technologies to develop effective FHB resistance and/or reduced DON accumulation.
