Background: Prunus armeniaca, divaricata, tianshanica, and domestica are valuable ancient tree species that have persisted since the end of Tertiary period within Tianshan wild fruit forest. However, evolutionary relationships among in forest long posed a challenge. Methods: We sequenced assembled chloroplast genomes P. incorporated genome data for comparative analysis to elucidate their phylogenetic positions genus Prunus. Results: The lengths these ranged from 157,395 bp 158,090 bp, with total 130 131 genes annotated, comprising 85 86 protein-coding genes, 8 rRNA 35 36 tRNA genes. Notably, four predominantly used high-frequency codons ending A/U. Additionally, we identified 300 simple repetitive sequences 166 across species. mutation sites were mainly found non-coding regions, seven regions high frequency identified. revealed five branches: subgenus Armeniaca, Microcerasus, Prunus, Amygdalus, Cerasus. estimated deviation time crown group is roughly 61.41 million years ago. Conclusions: This study provides exhaustive genetic evidence classification systematic establishes crucial foundation subsequent research into diversity history genus.
