• Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici ( Pst ), is a global threat to wheat 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 synthetic hexaploid wheat; transgenic plants with YrAS2388R show resistance to eleven Pst races in common wheat and one race of P . striiformis f. sp. hordei in barley. The YrAS2388R allele occurs only in Ae. tauschii and the Ae. tauschii -derived synthetic wheat; it is absent in 100% ( n  = 461) of common wheat lines tested. The cloning of YrAS2388R will facilitate breeding for stripe rust resistance in wheat and other Triticeae species. Stripe rust is a serious threat to wheat production. Here, the authors reveal that the resistance gene, only present in the wheat progenitor Aegilops tauschii and its derived synthetic wheat, encodes a nucleotide oligomerization domain-like receptor and confers resistance in common wheat and barley.
