Breeding for durable resistance against biotrophic fungal pathogens using transgenes from wheat.

ABSTRACT: Breeding for resistant crops is a sustainable way to control disease and relies on the introduction of novel resistance genes. Here, we tested three strategies on how to use transgenes from wheat to achieve durable resistance against fungal pathogens in the field. First, we tested the highly effective, overexpressed single transgene Pm3e in the background of spring wheat cultivar Bobwhite in a long-term field trial over many years. Together with previous results, this revealed that transgenic wheat line Pm3e#2 conferred complete powdery mildew resistance during a total of nine field seasons without a negative impact on yield. Furthermore, overexpressed Pm3e provided resistance to powdery mildew isolates from our worldwide collection when crossed into the elite wheat cultivar
