Research Project: Mapping Genes Underlying Fusarium Head Blight Variation to Target

Location: Crop Production and Protection

Project Number: 0500-00053-005-162-G
Project Type: Grant

Start Date: May 1, 2022
End Date: Apr 30, 2024

1. In laboratory experiments, measure DON levels, fungicide sensitivity, ascospore discharge, and mycelial growth for 150 Fg isolates. 2. Phenotype 150 Fg isolates for aggressiveness and DON production via greenhouse head inoculations on susceptible and resistant wheat. 3. Perform genome-wide association to identify SNPs associated with variation in above traits.

Genome-wide association studies (GWAS) offer a powerful method for mapping the genetic variants segregating in natural populations that underlie quantitative traits. Our project will expand the use of GWAS in fungal plant pathogens with the goal of finding targets of control, focusing on traits such as DON production, fungicide resistance, and aggressiveness.
