Research Project: Genetics of Aggressiveness in Fusarium graminearum

Location: Crop Production and Protection

Project Number: 0500-00053-005-160-G
Project Type: Grant

Start Date: May 1, 2022
End Date: Apr 30, 2026

1) Evaluate Mendelian segregation patterns among progeny of crosses from different Fusarium graminearum populations. 2) Determine whether individuals and mixtures of outcrossed progeny differ in susceptible or resistant wheat varieties with or without fungicides. 3) Identify DNA markers from genome sequence data from progeny pools differing in aggressiveness and toxigenicity.

We will use a classical genetic approach, combined with genome sequencing and SNP analysis, to test the hypothesis that 3ADON, compared with 15ADON, confers increased aggressiveness, toxigenicity, and competitiveness to F. graminearum, and to identify markers linked to novel loci outside the TRI cluster contributing significantly to these important traits.
