Abstract
Prunus mongolica and Prunus pedunculata are two shrub species with high ecological and economic values, and have experienced population decline and range contraction during the past decades. To promote their conservation and restoration, complete chloroplast (cp) genomes were assembled using next-generation sequencing technology in this study. The cp genomes of P. mongolica and P. pedunculata were 158,039 and 157,851 bp in length, respectively, and both comprise a pair of inverted repeat regions, separated by a large single-copy region and a small single-copy region. A total of 111 gene species were annotated for both species, including 78 protein-coding (PCG), 29 tRNA and four rRNA gene species; nineteen gene species are completely or partially duplicated within the IR regions. P. mongolica was found to be closely related to the congeners P. kansuensis and P. persica, while P. pedunculata to P. humilis and P. mume.
