Phylogenetic analysis of the complete chloroplast genome of Prunus persica seed as the Chinese herbal medicine to China

Abstract

The seed of Prunus persica is a kind of commonly used Chinese herbal medicine in orthopedics at China. In this study, we assembled and annotated the complete chloroplast genome of P. persica. The chloroplast genome size was 157,704 bp as a circle, which contained a large single-copy region (LSC, 85,883 bp), a small single-copy region (SSC, 19,061 bp) and a pair of inverted repeat regions (IR, 26,380 bp). The overall nucleotide composition is: 31.1% of A (49,092 bp), 32.1% T (50,709 bp), 18.8% C (29,625 bp) and 18.0% G (28,278 bp), with a total G + C content of the chloroplast genome 36.8% and A + T of 63.2%. The chloroplast genome of P. persica contains 123 genes, which included 78 protein-coding genes (PCG), 37 transfer RNA (tRNAs) and 8 ribosome RNA (rRNAs). Furthermore, the phylogenetic analysis based on 14 plants species confirmed the position of P. persica closely related to Prunus mongolica.
