Abstract

In one aspect, this disclosure relates to a wheat plant, plant part or plant cell that has increased resistance to powdery mildew, wherein said plant comprises a loss of function mutation in the coding regions of two alleles selected from TaMLO-A1, TaMLO-B1 and TaMLO-D1 and reduced expression of the third TaMLO allele. In another aspect, this disclosure provides a method for producing a wheat plant, plant part or plant cell with increased resistance to powdery mildew, wherein the method comprises using targeted genome modification comprising introducing a loss of function mutation into the coding regions of two MLO alleles selected from TaMLO-A1, TaMLO-B1 and TaMLO-D1 and decreasing expression of the third TaMLO allele.
