Abstract Powdery mildew, caused by Blumeria graminis f. sp. tritici ( Bgt ), is one of the most destructive diseases that pose a great threat to wheat production. Wheat landraces represent rich source powdery mildew resistance. Here, we report map-based cloning resistance gene Pm24 from Chinese landrace Hulutou. It encodes tandem kinase protein (TKP) with putative kinase-pseudokinase domains, designated WHEAT TANDEM KINASE 3 (WTK3). The function was validated transgenic assay, independent...
Abstract Crop wild relatives offer natural variations of disease resistance for crop improvement. Here, we report the isolation broad-spectrum powdery mildew gene Pm36 , originated from emmer wheat, that encodes a tandem kinase with transmembrane domain (WTK7-TM) through combination map-based cloning, PacBio SMRT long-read genome sequencing, mutagenesis, and transformation. Mutagenesis assay reveals two domains WTK7-TM are critical function. Consistently, in vitro phosphorylation shows...
Tandem kinase proteins underlie the innate immune systems of cereal plants, but how they initiate plant responses remains unclear. This report identifies wheat protein tandem NBD 1 (WTN1), a noncanonical nucleotide-binding leucine-rich repeat (NLR) receptor featuring nucleotide binding adaptor shared by APAF-1, R proteins, and CED-4 (NB-ARC) domains, required for WTK3-mediated disease resistance. Both WTK3 its allelic variant Rwt4—known conferring resistance to powdery mildew blast,...
Summary Powdery mildew, a fungal disease caused by Blumeria graminis f. sp. tritici ( Bgt ), has serious impact on wheat production. Loss of resistance in cultivars prompts continuing search for new sources resistance. Wild emmer Triticum turgidum ssp. dicoccoides , WEW), the progenitor both modern tetraploid and hexaploid wheats, harbors many powdery mildew genes. We report here positional cloning functional characterization Pm41 gene derived from WEW, which encodes coiled‐coil,...
Summary Powdery mildew poses severe threats to wheat production. The most sustainable way control this disease is through planting resistant cultivars. We report the map‐based cloning of powdery resistance allele Pm5e from a Chinese landrace. applied two‐step bulked segregant RNA sequencing (BSR‐Seq) approach in developing tightly linked or co‐segregating markers . first BSR‐Seq used phenotypically contrasting bulks recombinant inbred lines (RILs) identify ‐linked markers. second utilized...
High-density genetic linkage maps are necessary for precisely mapping quantitative trait loci (QTLs) controlling grain shape and size in wheat. By applying the Infinium iSelect 9K SNP assay, we have constructed a high-density map with 269 F 8 recombinant inbred lines (RILs) developed between Chinese cornerstone wheat breeding parental line Yanda1817 high-yielding Beinong6. The contains 2431 SNPs 128 SSR & EST-SSR markers total coverage of 3213.2 cM an average interval 1.26 per marker....
Stripe rust and powdery mildew are both devastating diseases for durum common wheat. Pyramiding of genes conferring resistance to one or more in a single cultivar is an important breeding approach provide broader spectra resistances wheat improvement. A new gene originating from wild emmer (Triticum turgidum var. dicoccoides) backcrossed into (T. aestivum) line WE35 was identified. It conferred intermediate level Blumeria graminis f. sp. tritici isolate E09 at the seedling stage high adult...
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important wheat diseases in world. In this study, a single dominant powdery mildew resistance gene MlIW172 was identified IW172 wild emmer accession and mapped to distal region chromosome arm 7AL (bin7AL-16-0.86-0.90) via molecular marker analysis. closely linked with RFLP probe Xpsr680-derived STS Xmag2185 EST markers BE405531 BE637476. This suggested that might be allelic Pm1 locus or new Pm1. By screening...
Wheat powdery mildew is caused by Blumeria graminis f. sp. tritici (Bgt), a biotrophic fungal species. It very important to mine new (Pm) resistance genes for developing resistant wheat cultivars reduce the deleterious effects of disease. This study was carried out characterize Pm gene in Qingxinmai, winter landrace from Xinjiang, China. Qingxinmai many Bgt isolates collected different fields F 1 , 2 and 2:3 generations cross between susceptible line 041133 were developed. confirmed that...
Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici (PST), is one of the most devastating fungal diseases in common wheat (Triticum aestivum L.) China and worldwide. Resistance breeding effective strategy to control crop plants. Chinese lines Mengmai 58 Huaiyang 1 are highly resistant PST race CYR34 (V26) at adult plant stage. To genetically map underlying resistance genes we developed segregating populations crossing with susceptible cultivar Nongda 399. The stripe...
Leaf senescence is normally the last stage of plant development. Early functional leaves significantly reduces photosynthetic time and efficiency, seriously affecting grain yield quality in wheat. Discovering genes responsible for early leaf (els) are necessary developing novel germplasms cultivars with delayed leaf-senescence through molecular manipulation marker assisted selection. In this study, we identified an line M114 a derivative wheat breeding population. Genetic analysis indicated...
As a large plant-specific gene family, the NAC (NAM, ATAF1/2, and CUC2) transcription factor is related to plant growth, development, response abiotic stresses. Although draft genome of garden asparagus (Asparagus officinalis) has been released, genome-wide investigation family still unavailable. In this study, total 85 A. officinalis genes were identified, comprehensive analysis was performed, including physicochemical properties, phylogenetic relationship, chromosome localization,...
The wax (glaucousness) on wheat leaves and stems is mainly controlled by two sets of genes: glaucousness loci (W1 W2) non-glaucousness (Iw1 Iw2). (Iw) act as inhibitors the (W). High-resolution comparative genetic linkage maps Iw1 originating from Triticum dicoccoides, Iw2 Aegilops tauschii were developed genomics analyses Brachypodium, sorghum rice genomic sequences corresponding to syntenic regions Iw in wheat. Eleven eight linked EST markers mapped distal chromosomes 2BS 2DS,...
Abstract Background Grain weight is an important yield component. Selection of advanced lines with heavy grains show high grain sink potentials and strong activity, which increasingly objective in wheat breeding programs. Rice OsGS3 has been identified as a major quantitative trait locus for both size. However, allelic variation GS3 not characterized previously hexaploid wheat. Results We cloned 2445, 2393, 2409 bp sequences the homologs TaGS3-4A , TaGS3-7A TaGS3-7D ‘Changzhi 6406’, cultivar...
