“…Thus, the absence of a TraesCS1B02G071642.1 ortholog in the non-restorer rye suggests it as an attractive Rf multi candidate. The only current implementations of a wheat- rye Rf multi CMS system involve 1RS.1BL translocations 5,58,61 , which are typically linked to reduced baking quality 40 . Breaking this linkage may now benefit from marker development and/or genome editing approaches targeting TraesCS1B02G071642.1 .…”

We present a chromosome-scale annotated assembly of the rye (Secale cereale L. inbred line ‘Lo7’) genome, which we use to explore Triticeae genomic evolution, and rye’s superior disease and stress tolerance. The rye genome shares chromosome-level organization with other Triticeae cereals, but exhibits unique retrotransposon dynamics and structural features. Crop improvement in rye, as well as in wheat and triticale, will profit from investigations of rye gene families implicated in pathogen resistance, low temperature tolerance, and fertility control systems for hybrid breeding. We show that rye introgressions in wheat breeding panels can be characterised in high-throughput to predict the yield effects and trade-offs of rye chromatin.

“…We use the term wheat–rye translocation line(s) to designate hexaploid wheat (ABD genome; T. aestivum ) that possesses part of the rye genome (R; S. cereale ) in the form of chromosome translocations [6] , [7] , [8] . Near-isolines (NILs) were developed by backcross introgression to form BC 3 F 3:4 (‘Coker 797’ *4/‘Hamlet’) [9] and differed in the presence or absence of the long arm of rye chromosome 2 (2RL) derived from the diploid rye ‘Chaupon’ [9] , [10] .…”

Studying gene expression in wheat–rye translocation lines is complicated due to the presence of homeologs in hexaploid wheat and high levels of synteny between wheat and rye genomes (Naranjo and Fernandez-Rueda, 1991 [1]; Devos et al., 1995 [2]; Lee et al., 2010 [3]; Lee et al., 2013 [4]). To overcome limitations of current gene expression studies on wheat–rye translocation lines and identify genome-specific transcripts, we developed a custom Roche NimbleGen Gene Expression microarray that contains probes derived from the sequence of hexaploid wheat, diploid rye and diploid progenitors of hexaploid wheat genome (Lee et al., 2014). Using the array developed, we identified genome-specific transcripts in a wheat–rye translocation line (Lee et al., 2014). Expression data are deposited in the NCBI Gene Expression Omnibus (GEO) under accession number GSE58678. Here we report the details of the methods used in the array workflow and data analysis.

“…Hard red spring wheat (HRSW) is grown in the northern Great Plains of the United States and Prairie Provinces of Canada. Most of the HRSW grain is used for making leavened bread both domestically and internationally (Jung & Seo, 2014; Tilley et al, 2012; Zilić et al., 2011). A challenge in wheat breeding is that there is often interaction between agronomic and end‐use quality traits resulting in an often‐negative impact on one or the other.…”

“…Wide crosses to progenitor species for improved GY performance have the potential to negatively impact end‐use quality. Crosses between hexaploid wheat and rye ( Secale cereal L.) for the introgression of resistance genes located on the short arm of rye chromosome 1 (1RS) provide an example (Jung & Seo, 2014). Wheat‐rye translocations including 1BL/1RS and 1Al/1RS were introduced as a source for resistance to stem rust ( Puccinia graminis f. sp.…”

Impact of yield component alleles from durum wheat on end‐use quality of spring wheat

Background and objectives Hard red spring wheat (Triticum aestivum L.) (HRSW) is used for bread baking while durum wheat (Triticum turgidum L. ssp. durum) is used for pasta production. This study investigated the impact of alleles from durum wheat for yield component traits on HRSW end‐use quality traits. Near‐isogenic lines for four quantitative trait loci, QGw.mst‐3B, QGw.mst‐7A, QTn.mst‐5B, and QYld.mst‐2B, were evaluated in rainfed and irrigated environments. Findings Durum alleles were found to significantly impact end‐use quality at all four loci. The durum allele QGw.mst‐3B for increased kernel weight (KWT) positively impacted end‐use quality traits with increases in kernel protein and loaf volume. The durum allele at QTn.mst‐5B delayed heading date, impacting productive tiller number and KWT and additional end‐use quality traits. The durum allele at QYld.mst‐2B for GY showed both positive and negative effects on end‐use quality. The durum allele for reduced spikelet number per spike at QGw.mst‐7A had little to no impact on end‐use quality. Conclusions Results from the present study indicate that the alleles from durum wheat are potential sources of cultivar improvement; however, interactions between yield component and end‐use quality traits may influence utilization. Significance and novelty This study demonstrates the potential utility of introgressed durum yield component alleles for genetic improvement in HRSW.
