    Abstract Cultivated wheat is continually exposed to various pathogens. Blumeria graminis f. sp. tritici (Bgt) causes powdery mildew disease and significant yield loss. Pm60 was cloned from Triticum urartu and confers race‐specific powdery mildew resistance in wheat. Pm60a and Pm60b are allelic variants of Pm60 and have two leucine‐rich repeat motifs deletions and insertions, respectively, which were detected in other T. urartu accessions. Through map‐based cloning, virus‐induced gene silencing, and stable transformation assays, we demonstrated that Pm60a and Pm60b conferred Bgt E09 resistance resembling that provided by Pm60. However, the homozygous Pm60a (but not Pm60 or Pm60b) transformants driven by the native promoters lacked race‐specific resistance when they were inoculated with Bgt E18. As all three T. urartu accessions contained the three foregoing alleles, they had high resistance to Bgt E18. Pyramiding Pm60a with either of the allelic genes in F₁ plants did not cause mutual allele suppression or interference with Bgt E18 resistance. Deletion (but not insertion) of the two leucine‐rich repeat motifs in Pm60a substantially narrowed the resistance spectrum. In T. urartu accession PI428210, we identified another locus adjacent to Pm60a and resistant to Bgt E18. Characterization of the alleles at the Pm60 locus revealed their diversity and similarity and may facilitate wheat breeding for resistance to powdery mildew disease caused by B. graminis f. sp. tritici.

    Abstract BACKGROUND: YrU1 is a nucleotide-binding site (NBS) and leucine-rich repeat (LRR) protein (NLR), with additional ankyrin-repeat and WRKY domains and confers effective resistance to stripe rust fungus Puccinia striiformis f. sp. Tritici (Pst). YrU1 was positionally cloned in the progenitor species of the A genome of bread wheat, Tricicum urartu, recently. However, the molecular mechanism and components involved in YrU1-mediated resistance are not clear. RESULTS: In this study, we found that the transcript level of TuRLK1, which encodes a novel leucine-rich repeat receptor-like kinase, was up-regulated after inoculation with Pst in the presence of YrU1, through RNA-seq analysis in T. urartu accession PI428309. TuRLK1 contained only a small number of LRR motifs, and was localized in the plasma-membrane. Transient expression of TuRLK1 induced hypersensitive cell death response in N. benthamiana leaves. Silencing of TuRLK1, using barley stripe mosaic virus (BSMV)-induced gene silencing (VIGS) system in PI428309 that contains YrU1, compromised the resistance against stripe rust caused by Pst CY33, indicating that TuRLK1 was required for YrU1-activated plant immunity. Furthermore, overexpression of TuRLK1 could enhance powdery mildew resistance in bread wheat and Arabidopsis thaliana after inoculating with the corresponding pathogens. CONCLUSIONS: Our study indicates that TuRLK1 is required for immune response mediated by the unique NLR protein YrU1, and likely plays an important role in disease resistance to other pathogens.

    Abstract Perception of pathogenic effectors in plants often relies on nucleotide-binding domain (NBS) and leucine-rich-repeat-containing (NLR) proteins. Some NLRs contain additional domains that function as integrated decoys for pathogen effector targets and activation of immune signalling. Wheat stripe rust is one of the most devastating diseases of crop plants. Here, we report the cloning of YrU1, a stripe rust resistance gene from the diploid wheat Triticum urartu, the progenitor of the A genome of hexaploid wheat. YrU1 encodes a coiled-coil-NBS-leucine-rich repeat protein with N-terminal ankyrin-repeat and C-terminal WRKY domains, representing a unique NLR structure in plants. Database searches identify similar architecture only in wheat relatives. Transient expression of YrU1 in Nicotiana benthamiana does not induce cell death in the absence of pathogens. The ankyrin-repeat and coiled-coil domains of YrU1 self-associate, suggesting that homodimerisation is critical for YrU1 function. The identification and cloning of this disease resistance gene sheds light on NLR protein function and may facilitate breeding to control the devastating wheat stripe rust disease.

    Abstract Powdery mildew is one of the most devastating diseases of wheat. To date, few powdery mildew resistance genes have been cloned from wheat due to the size and complexity of the wheat genome. Triticum urartu is the progenitor of the A genome of wheat and is an important source for powdery mildew resistance genes. Using molecular markers designed from scaffolds of the sequenced T. urartu accession and standard map-based cloning, a powdery mildew resistance locus was mapped to a 356-kb region, which contains two nucleotide-binding and leucine-rich repeat domain (NB-LRR) protein-encoding genes. Virus-induced gene silencing, single-cell transient expression, and stable transformation assays demonstrated that one of these two genes, designated Pm60, confers resistance to powdery mildew. Overexpression of full-length Pm60 and two allelic variants in Nicotiana benthamiana leaves induced hypersensitive cell death response, but expression of the coiled-coil domain alone was insufficient to induce hypersensitive response. Yeast two-hybrid, bimolecular fluorescence complementation and luciferase complementation imaging assays showed that Pm60 protein interacts with its neighboring NB-containing protein, suggesting that they might be functionally related. The identification and cloning of this novel wheat powdery mildew resistance gene will facilitate breeding for disease resistance in wheat.

    Abstract Triticeae species, including wheat, barley, and rye, are critical for global food security. Mapping agronomically important genes is crucial for elucidating molecular mechanisms and improving crops. However, Triticeae includes many wild relatives with desirable agronomic traits, and frequent introgressions occurred during Triticeae evolution and domestication. Thus, Triticeae genomes are generally large and complex, making the localization of genes or functional elements that control agronomic traits challenging. Here, we developed Triti-Map, which contains a suite of user-friendly computational packages specifically designed and optimized to overcome the obstacles of gene mapping in Triticeae, as well as a web interface integrating multi-omics data from Triticeae for the efficient mining of genes or functional elements that control particular traits. The Triti-Map pipeline accepts both DNA and RNA bulk-segregated sequencing data as well as traditional QTL data as inputs for locating genes and elucidating their functions. We illustrate the usage of Triti-Map with a combination of bulk-segregated ChIP-seq data to detect a wheat disease-resistance gene with its promoter sequence that is absent from the reference genome and clarify its evolutionary process. We hope that Triti-Map will facilitate gene isolation and accelerate Triticeae breeding.
