Harnessing Genomics Approaches for Heat Stress Resilience in Wheat: From Discovery to Deployment.

Climate Adaptation
Wheat fields across the Great Plains are already losing yield to spring heat waves that hit during flowering—the very window this research targets with new breeding tools.
Heat waves during the weeks when wheat plants are flowering and setting seed can devastate harvests. Researchers have been mapping which genes help wheat survive these heat spells, and now new tools like CRISPR gene editing and computer-assisted breeding programs are making it possible to breed tougher wheat varieties much more quickly. This review brings together everything scientists have learned and charts a path from lab discovery to actual seeds farmers can plant.
Key Findings
Heat stress during reproductive stages disrupts photosynthesis, speeds up leaf aging, and damages cellular structures—compounding yield losses at the most vulnerable growth window.
Multi-omics approaches (combining genomic, transcriptomic, and epigenetic data) have revealed that plants can retain a 'stress memory,' priming them to respond better to repeated heat events.
Tools like pangenomics, genomic prediction models, and CRISPR-based editing are now being integrated into breeding pipelines to accelerate development of heat-resilient cultivars.

Wheat is a group of wild and domesticated grasses of the genus Triticum. As cereals, they are cultivated for their grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat, spelt, durum, emmer, einkorn, and Khorasan or Kamut....
