Key messageSNP markers were developed for the OWBM resistance geneSm1that will be useful for MAS. The wheatSm1region is collinear with an inverted syntenic interval inB. distachyon.AbstractOrange wheat blossom midge (OWBM, Sitodiplosis mosellana Géhin) is an important insect pest of wheat (Triticum aestivum) in many growing regions. Sm1 is the only described OWBM resistance gene and is the foundation of managing OWBM through host genetics. Sm1 was previously mapped to wheat chromosome arm 2BS… 

Molecular mapping of major QTL conferring resistance to orange wheat blossom midge (Sitodiplosis mosellana) in Chinese wheat varieties with selective populations

The single-nucleotide polymorphism (SNP) markers AX-109543456,AX-108942696 and AX-110928325 were closely linked to the QTL and could be used for marker-assisted selection (MAS) for OWBM resistance in wheat breeding programs.

Screening for differential expression of genes for resistance to Sitodiplosis mosellana in bread wheat via BSR-seq analysis

Five putative candidate genes for OWBM resistance in Chinese winter wheat ‘Jimai 24’ were identified via BSR-seq and differential expression analyses and six new markers developed based on sequences of the five genes were also mapped in the same genomic region using genetic population.

Genetic analysis of oviposition deterrence to orange wheat blossom midge in spring wheat

A major QTL for oviposition deterrence to orange wheat blossom midge was detected on chromosome 1A in the Canadian breeding line BW278 that was inherited from the Chinese variety Sumai-3, an important insect pest of wheat that reduces both grain yield and quality.

Genetic Insight Into the Insect Resistance in Bread Wheat Exploiting the Untapped Natural Diversity

Climate change is an undeniable threat to sustainable wheat production in the future as an increased temperature will significantly increase grain loss due to the increased number of generations per

Marker-assisted breeding of hexaploid spring wheat in the Canadian prairies

A compilation of validated molecular markers that are polymorphic and potentially useful for Canadian wheat breeding, including single nucleotide polymorphism based markers, are presented.

Rapid identification of a major effect QTL conferring adult plant resistance to stripe rust in wheat cultivar Yaco“S”

The APR gene could be rapidly and accurately mapped and it is useful for improving stripe rust resistance in wheat breeding and combined SNP iSelect assay and kompetitive allele specific PCR technology is found.

Comparative Analysis of Coding and Non-Coding Features within Insect Tolerance Loci in Wheat with Their Homologs in Cereal Genomes

A comparative analysis of coding and non-coding features of these loci of wheat across important cereal crops, barley, rye, oat, and rice is presented, paving the way for cloning and editing of additional WSS and OWBM tolerance gene(s), proteins, and metabolites.

Multiple wheat genomes reveal global variation in modern breeding

Comparative analysis of multiple genome assemblies from wheat reveals extensive diversity that results from the complex breeding history of wheat and provides a basis for further potential improvements to this important food crop.

Wheat genomics and breeding: bridging the gap.

Abstract Recent technological advances in next-generation sequencing (NGS) technologies have dramatically reduced the cost of DNA sequencing, allowing species with large and complex genomes to be

Droplet digital PCR for verification of interspersed refuge in midge tolerant wheat varietal blends1

Analysis of bulk ground samples by droplet digital PCR (ddPCR) was investigated as an alternative to individual kernel testing for assessment of interspersed refuge in midge tolerant wheat varietal blends, yielding refuge estimates that were very close to the targeted proportions across the range simulated.



Chromosome location and markers of Sm1: a gene of wheat that conditions antibiotic resistance to orange wheat blossom midge

No DNA polymorphism associated with resistance was amplified following screening of about 500 Random Amplification of Polymorphic DNA (RAPD) primers on bulked segregants but linked Amplified Fragment Length Polymorphism (AFLP) fragments were identified by screening 57 primer combinations and an allele-specific Sequence Characterized Amplified Region (SCAR) DNA marker linked to midge resistance was elaborated from the sequence of one of these fragments.

Comparative genetic mapping and genomic region collinearity analysis of the powdery mildew resistance gene Pm41

Comparative genomics analysis of the markers flanking the Pm41 locus in wheat and the putative orthologous genes in Brachypodium, rice, and sorghum suggests that the gene order is highly conserved between rice and Sorghum.

Identification and comparative mapping of a powdery mildew resistance gene derived from wild emmer (Triticum turgidum var. dicoccoides) on chromosome 2BS

Four RGA-like sequences annotated in the orthologous Brachypodium genomic region could serve as chromosome landing target regions for map-based cloning of MlIW170, a powdery mildew resistance gene conferring resistance to B. tritici.

Genome analysis at different ploidy levels allows cloning of the powdery mildew resistance gene Pm3b from hexaploid wheat.

It is demonstrated that the combined analysis of genomes from wheat species with different ploidy levels can be exploited for positional cloning in bread wheat and that the candidate gene, a member of the coiled-coil nucleotide binding site leucine-rich repeat (NBS-LRR) type of disease resistance genes, is the Pm3b gene.

Genetic and comparative genomics mapping reveals that a powdery mildew resistance gene Ml3D232 originating from wild emmer co-segregates with an NBS-LRR analog in common wheat (Triticum aestivum L.)

This newly developed common wheat germplasm provides broad-spectrum resistance to powdery mildew and a valuable resource for wheat breeding programs.

Identification and comparative mapping of a dominant potyvirus resistance gene cluster in Capsicum

The results indicated that Pvr4, Pvr7, and Tsw, a gene conferring resistance to tomato spotted wilt virus, comprise the first identified cluster of dominant disease resistance genes in Capsicum L.

RNA-Seq bulked segregant analysis enables the identification of high-resolution genetic markers for breeding in hexaploid wheat.

The identification of genetic markers linked to genes of agronomic importance for wheat yellow rust, using a segregating F2 population, demonstrates that the proposed methodology can be applied in polyploid F2 populations to generate high-resolution genetic maps across target intervals.

Inheritance of resistance to wheat midge, Sitodiplosis mosellana, in spring wheat

A powerful resistance gene, designated Sm1, is simply inherited and can be incorporated readily into breeding programmes for spring or winter wheat, however, the use of this gene by itself may lead to the evolution of a virulent population, once a resistant cultivar is widely grown.

A chromosome-based draft sequence of the hexaploid bread wheat (Triticum aestivum) genome

Insight into the genome biology of a polyploid crop provide a springboard for faster gene isolation, rapid genetic marker development, and precise breeding to meet the needs of increasing food demand worldwide.

A haplotype map of allohexaploid wheat reveals distinct patterns of selection on homoeologous genomes

The results suggest that duplicated homoeologous genes are under purifying selection, and it is hypothesized that allopolyploidy may have increased the likelihood of beneficial allele recovery by broadening the set of possible selection targets.
