production. Aegilops tauschii, one of the wheat progenitors, carries the YrAS2388 locus for
resistance to Pst on chromosome 4DS. We reveal that YrAS2388 encodes a typical
nucleotide oligomerization domain-like receptor (NLR). The Pst-resistant allele YrAS2388R
has duplicated 3'untranslated regions and is characterized by alternative splicing in the
nucleotide-binding domain. Mutation of the YrAS2388R allele disrupts its resistance to Pst in …
