  • Analysis of 46 newly sequenced or re-sequenced Tausch’s goatgrass (Aegilops tauschii) accessions establishes the origin of the bread wheat (Triticum aestivum) D genome from genetically and geographically discrete Ae. tauschii subpopulations.

  • Leaf rust and stripe rust of wheat are two important fungal diseases of cultivated wheat and they are caused by infection of different pathogens. Here, the authors report the nucleotide-binding leucine-rich repeat (NLR) protein encoding gene Yr87/Lr85 confers resistance to both diseases.

  • A pangenome analysis of 76 wild and domesticated barley accessions in combination with short-read sequence data of 1,315 barley genotypes indicates that allelic diversity at structurally complex loci may have helped crop plants to adapt to agricultural ecosystems.

  • Strain Ug99 of the wheat stem rust pathogen, Puccinia graminis f. sp. tritici, is a major threat to global food security. Here, the authors present genomic analyses supporting that Ug99 arose as a result of non-sexual genetic exchange between dikaryotic ancestors.

  • The genes underlying stripe rust host specificity between wheat and barley remain unknown. Here, the authors report that Rps6, Rps7 and Rps8 determine host species specificity in barley at different stages of the pathogen lifecycle and the barley powdery mildew immune receptor Mla8 and Rps7 are the same gene.

  • Aegilops sharonensis is a wild diploid relative of wheat. Here, the authors assemble the genome of Ae. sharonensis and use the assembly as an aid to clone the Ae. sharonensis-derived stem rust resistance gene Sr62 in the allohexaploid genome of wheat.

  • The resistance gene Sr43, which was crossed into bread wheat from the wild grass Thinopyrum elongatum, encodes an unusual protein kinase fusion protein that confers wheat stem rust resistance.

  • Clare Lewis et al. report the first identification in nearly 60 years of a cultivated wheat plant infected with the fungal pathogen Puccinia graminis f.sp. tritici (wheat stem rust) in the United Kingdom. They find that only 20% of UK wheat varieties are resistant to this strain and urge growers to resume resistance breeding programs.

  • Delorean et al., along with colleagues from the Open Wild Wheat Consortium, present an analysis of Aegilops tauschii genomes to investigate the origins of the Glu-D1 gene in modern wheats. They discover an abundance of novel Glu-D1 gene alleles that could serve as a reservoir for generating higher quality wheat varieties. This is a companion to the Consortium paper which is available in Nature Biotechnology.
