Abstract: Methods and recombinant vectors for increasing resistance to Fusarium head blight (FHB) infection in plants. Exogenous Fhb1 nucleic acids are described to generate transgenic plants having increased resistance to FHB relative to a control plant. The nucleotide sequence of the exogenous nucleic acid comprises SEQ ID NO:1, 2, 4, 5, or 6; has at least 95% sequence identity to SEQ ID NO:1, 2, 4, 5, or 6; encodes a protein comprising the amino acid sequence of SEQ ID NO: 3, 7, 8, or 9; or encodes a protein having at least 95% amino acid identity to SEQ ID NO: 3, 7, 8, or 9.

Abstract: A protein conferring resistance to Fusarium Head Blight disease (FHB) is described, along with the DNA sequence of the corresponding gene and mRNA copy (cDNA). The cDNA of Fhb1 gene can be used to produce genetically-modified plants having increased resistance to FHB, particularly in wheat, barley and other plants affected by the disease. The protein has antifungal properties and inhibits fungal growth, thereby providing a means for reducing DON toxin in grains. Conserved functional domains are identified in the protein. Genetically-modified plants having increased resistance FHB are also described, along with methods for producing such genetically-modified plants.
