Rose pangenome maps 55,000 genes, opening new path for breeding

Phys · · 357 words · By INRAE

An international research team successfully sequenced and decoded the complete genetic information of the rose genus, resulting in the first rose pangenome, which annotated over 55,000 genes. These findings, published in Nature Genetics, reveal the complex evolutionary history of roses and identify genetic regulators for traits like flower color and fragrance. The research is expected to accelerate breeding programs for ornamental roses and potentially benefit other species in the Rosaceae family.
