Section: A Comparison Of the Coding Features Across Genomic Regions Homologous To Additional Loci Associated With Owbm Resistance Suggestmentioning

“…Another major QTL for OWBM resistance was mapped to the long arm of chromosome 4A in wheat, where the candidate gene has not been identified yet [25,30]. While relatively few markers have been mapped to this resistance loci, a 4.9 Mb genomic region has been defined on the previous assembly of the Chinese Spring genome (IWGSC v1.0 assembly) that included 58 genes [25]. Therefore, the longest isoforms encoded by these genes were used to identify the transcripts that may be associated with the 4AL-QTL in the current version of the Chinese Spring genome (IWGSC v2.1 assembly) as well as homologous transcripts in Svevo, Zavitan, barley, rye, and rice.…”

“…Even though the antibiosis-related Sm1 gene has been the only resource utilized in OWBM management strategies in the field so far, antixenosis-related mechanisms have been observed in common and durum wheat that can also be utilized to grow resilient crops [24,25]. Accordingly, a major QTL on chromosome 1A, QSm.mst-1A, was first identified in 2011 in the spring wheat variety Reeder [26].…”

“…This QTL was associated with oviposition deterrence again in a recent study and was saturated with molecular markers to facilitate cloning and marker-assisted selection efforts. Finally, another QTL on chromosome 4A has attracted attention for potential use against OWBM through oviposition deterrence [25]. So far, the causal genes underlying the antixenosis responses conferred by these QTL are unknown.…”

Food insecurity and malnutrition have reached critical levels with increased human population, climate fluctuations, water shortage; therefore, higher-yielding crops are in the spotlight of numerous studies. Abiotic factors affect the yield of staple food crops; among all, wheat stem sawfly (Cephus cinctus Norton) and orange wheat blossom midge (Sitodiplosis mosellana) are two of the most economically and agronomically harmful insect pests which cause yield loss in cereals, especially in wheat in North America. There is no effective strategy for suppressing this pest damage yet, and only the plants with intrinsic tolerance mechanisms such as solid stem phenotypes for WSS and antixenosis and/or antibiosis mechanisms for OWBM can limit damage. A major QTL and a causal gene for WSS resistance were previously identified in wheat, and 3 major QTLs and a causal gene for OWBM resistance. Here, we present a comparative analysis of coding and non-coding features of these loci of wheat across important cereal crops, barley, rye, oat, and rice. This research paves the way for our cloning and editing of additional WSS and OWBM tolerance gene(s), proteins, and metabolites.

“…However, there is anecdotal evidence that earlier flowering varieties previously grown in the UK (e.g., ‘Cordiale’) have high OWBM infection levels so further detailed characterization is required. Given the narrow genetic basis of current OWBM resistance (Zhang et al., 2020), the availability of a wider selection of varietal flowering time ranges may support the varietal blending approach developed and deployed to counter new virulences in Canada (Smith et al., 2014). Combined with deployment of additional genetic sources of resistance (Zhang et al., 2020) this should provide a more robust resistance package for UK farmers.…”

Climate change presents challenges to agricultural production systems. Wheat is a significant crop in the United Kingdom, occupying 40% of arable land area. Increased temperatures and drought risk are predicted to lead to future productivity losses. Plant breeders and researchers are working to develop more resilient wheat varieties although are often driven by different motivating factors compared to farmers. Here, we report on a dialog with agronomists working with farmers in wheat‐producing regions throughout the UK to gain greater understanding of the farm‐level importance of wheat flowering time and maturity along with the future opportunities and risks presented by earlier flowering varieties.
