摘要：Rosa davurica Pall. var. davurica is a member of the plant family Rosaceae. Although R. davurica has high application value, its chloroplast genome sequence has not been reported. This study aims to reveal the genetic characteristics of the chloroplast genome of Rosa roxburghii. The length of its total chloroplast DNA is 156,971 bp, with 37.22% G/C content. Its chloroplast genome has two inverted repeat (IRa and IRb) regions totaling 26,051 bp which are separated by a large single copy (LSC) region of 86,032 bp and a small single copy (SSC) region of 18,837 bp. The genome contains 131 independent genes (86 protein-coding, 37 tRNA, and 8 rRNA), and there are 18 repeated genes within the IR region. Among these genes, 17 genes contained one or two introns. The phylogenetic analysis showed that R. davurica was relatively close to other Rosa species, such as the Rosa hybrid.
