Fusarium head blight (FHB) is a fungal disease that devastates global wheat production, with losses of billions of dollars annually. Unlike foliar diseases, FHB occurs directly on wheat spikes (inflorescences). The infection lowers grain yield and also causes the grain to be contaminated by mycotoxins produced by the Fusarium pathogen, thus imposing health threats to humans and livestock. Although plant breeders have improved wheat resistance to FHB, the lack of wheat strains with stable FHB resistance has limited progress.
