Characterization of the complete chloroplast genome of Rumex nepalensis (Polygonaceae)

Abstract

Rumex nepalensis (Polygonaceae) is a fairly common perennial herb of high altitudes. In this study, we determined the complete chloroplast genome (plastome) of R. nepalensis with genome-skimming method. The complete plastome of R. nepalensis was 159,110 bp in length with a quadripartite structure, including a large single-copy region of 84,810 bp, a small single-copy region of 13,044 bp, and a pair of inverted repeats regions of 30,628 bp. The overall guanine-cytosine (GC) content was 37.5%. A total of 112 unique genes was annotated in this plastome, including 78 protein-coding genes, 30 tRNA genes, and four rRNA genes. In the ML tree, R. nepalensis was sister to R. crispus, and Rumex was sister to a clade comprising Rheum and Oxyria within Polygonaceae famliy.
