The virulence gene <i>ToxB</i> is both amplified and disrupted by transposons in the wheat pathogen <i>Pyrenophora tritici-repentis</i>

2025-11-13

Abstract excerpt

<h4>Summary</h4> Mechanisms that drive virulence gene duplication in plant pathogenic fungi remain poorly understood. In Pyrenophora tritici-repentis ( Ptr ), responsible for tan spot of wheat, ToxB is a multicopy virulence gene encoding a proteinaceous necrotrophic effector. ToxB exhibits a virulence dosage effect, where higher copy numbers are associated with increased disease severity. In this work, we sou...
