Wheat TaNADPO Promotes Spot Blotch Resistance.

ABSTRACT: Bipolaris sorokiniana is a prevalent fungal pathogen that resides in the soil and affects various parts of wheat, leading to diseases such as spot blotch, common root rot, head blight and black point. The genetic mechanisms that confer resistance in wheat against this pathogen are not completely known. In this research, 1302 wheat germplasms from around the world were evaluated for resistance to spot blotch at the seedling stage, and it was found that merely 3.8% displayed moderate or better resistance. A genome-wide association study (GWAS) employing high-density 660K single-nucleotide polymorphism (SNP) data pinpointed a segment on chromosome 1BL (621.2-674.0 Mb) containing nine SNPs that are significantly linked to spot blotch resistance, named Qsb.hebau-1BL.
