The haplotype-phased genome assembly facilitated the deciphering of the bud dormancy-related QTLs in Prunus mume.

Bud dormancy is a vital physiological process in woody perennials, facilitating their adaptation to seasonal environmental changes. Satisfying genotype-specific chilling requirements (CR) and heat requirements (HR) through exposure to specific chilling and warm temperatures is essential for dormancy release and the subsequent resumption of growth. The genetic mechanisms regulating bud dormancy traits in Prunus mume remain unclear.
