Prunus conradinae, a valuable flowering cherry belonging to the Rosaceae family subgenus Cerasus and endemic to China, has high economic and ornamental value. However, a high-quality P. conradinae genome is unavailable, which hinders our understanding of its genetic relationships and phylogenesis, and ultimately, the possibility of mining of key genes for important traits. Herein, we have successfully assembled a chromosome-scale P. conradinae genome, identifying 31,134 protein-coding genes, with 98.22% of them functionally annotated. Furthermore, we determined that repetitive sequences constitute 46.23% of the genome. Structural variation detection revealed some syntenic regions, inversions, translocations, and duplications, highlighting the genetic diversity and complexity of Cerasus. Phylogenetic analysis demonstrated that P. conradinae is most closely related to P. campanulata, from which it diverged ~ 19.1 million years ago (Mya). P. avium diverged earlier than P. cerasus and P. conradinae. Similar to the other Prunus species, P. conradinae underwent a common whole-genome duplication event at ~ 138.60 Mya. Furthermore, 79 MADS-box members were identified in P. conradinae, accompanied by the expansion of the SHORT VEGETATIVE PHASE subfamily. Our findings shed light on the complex genetic relationships, and genome evolution of P. conradinae and will facilitate research on the molecular breeding and functions of key genes related to important horticultural and economic characteristics of subgenus Cerasus.
