Scientists have demonstrated a new way to overcome one of agriculture’s most stubborn genetic dilemmas: improving crop resilience without sacrificing yield. Most genomics-assisted breeding programs compare crop varieties against a single reference genome and focus primarily on single-nucleotide polymorphisms, or SNPs. The pangenome revealed a gene called FtRNH in high-altitude wild plants but not in the cultivated varieties examined by the researchers. The gene is involved in repairing DNA damage caused by UV-B radiation, providing a plausible molecular explanation for the enhanced stress tolerance of wild high-altitude buckwheat.
