摘要： Prunus zhengheensis is a novel species originated in Fujian province, China. However, there is no further information available on its classification and molecular biology study. In this study, we first report the complete chloroplast (cp) genome sequence of P. zhengheensis. The cp genome of P. zhengheensis is 158,106 bp and GC content is 36.73%, is a circular structure composed of LSC (large single copy), SSC (small single copy), and IR (inverted repeat) regions, with the size of the three regions being 86,321 bp, 18,999 bp and 26,393 bp, respectively. The cp genome of P. zhengheensis contains 130 genes, and 242 SSRs are identified in the cp genome. The comparative analysis of cp genomes in eight Prunus plants demonstrates the subtle divergences occur in the protein-coding gene rps18, rps12, psbF, rpl33, matK, and rbcL, and that the KA/KS nucleotide substitution ratio of the ndhF of P. zhengheensis and P. armeniaca is 1.79636. The phylogenetic results indicate that the P. zhengheensis is closely related to P. mume, compared to other species of Prunus. Our research results provide the important genomic information for molecular phylogeny of P. zhengheensis.
