Abstract

The complete chloroplast genome sequence of traditional Tibetan herb, Maxim. was analyzed. The complete chloroplast genome of is 162,213 bp in size and has a 27.27% GC content. In the typical circular quadripartite structure, there was a pair of inverted repeat (IR) regions with 31,023 bp in length, which separated by a large single-copy (LSC) region (87,424 bp) and a small single-copy (SSC) region (12,743 bp). The chloroplast genome of contained 131 unigenes, which was composed of 86 protein-coding genes, 37 tRNA and 8 rRNA genes. Moreover, 238 SSRs were identified and 58.8% of them existed in LSC region. A maximum likelihood (ML) phylogenetic analysis based on chloroplast genomes indicated that was closely related to , , and . Our results would provide a valuable resource for resource utilization and the phylogenetic studies of Rheum in Polygonaceae.
