The complete chloroplast genome of Prunus domestica L. (Rosaceae) and its phylogenetic implication.

ABSTRACT: Prunus domestica commonly known as European plum is one of the most important wild fruit tree resources, and up to date, its wild community has only been found to be distributed in wild fruit forest area of the Tianshan Mountainsin Ili region of Xinjiang, China. Despite its agricultural importance and long history of cultivation, many questions remain about the origin of this species, due to absence of genome data. In this study, the complete chloroplast (cp) genome sequence of P. domestica was determined using next-generation sequencing. The entire cp genome was determined to be 157,395 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 85,744 and 18,949 bp, respectively, which were separated by a pair of 26,351 bp inverted repeat (IR) regions. The genome contained 130 genes, including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 36.8%. A phylogenetic tree reconstructed by 39 chloroplast genomes reveals that P. domestica is most closely related to Prunus salicina.
