These current policies bring to mind that Persian poem, loosely translated as: "A man was sawing off the branch on which he sat. The Master of the garden looked on and said, 'If this man does harm, it is not to me, But to his own self and well-being.'"

China's wheat breeding history unveiled with 17 genome assemblies, revealing 249,976 structural variations, 49.03% over 1 Kb. Insights for breeding progress! PMID:39604736, Nature 2025, @Nature doi.org/10.1038/s41586-024-08277-0 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪

Pan-genome bridges wheat structural variations with habitat and breeding | Nature
Wheat is the second largest food crop with a very good breeding system and pedigree record in China. Investigating the genomic footprints of wheat cultivars will unveil potential avenues for future breeding efforts1,2. Here we report chromosome-level genome assemblies of 17 wheat cultivars that chronicle the breeding history of China. Comparative genomic analysis uncovered a wealth of structural rearrangements, identifying 249,976 structural variations with 49.03% (122,567) longer than 5 kb. Cultivars developed in 1980s displayed significant accumulations of structural variations, a pattern linked to the extensive incorporation of European and American varieties into breeding programmes of that era. We further proved that structural variations in the centromere-proximal regions are associated with a reduction of crossover events. We showed that common wheat evolved from spring to winter types via mutations and duplications of the VRN-A1 gene as an adaptation strategy to a changing
