The complete chloroplast genome of a medical herb, Halenia elliptica D.Don (Gentianaceae), from Qinghai-Tibet Plateau in China

Abstract

Halenia elliptica D.Don (Gentianaceae) is one of the genuine medicinal species in Qinghai-Tibet Plateau, China. Here we report the first chloroplast (cp) genome of H. elliptica using Illumina HiSeq X Ten platform. The length of its complete cp genome is 153,341 bp, containing four sub-regions; a large single-copy region (LSC) of 82,811 bp and a small single-copy region (SSC) of 18,278 bp, which are separated by a pair of inverted repeat regions (IRs) of 26,126bp each. The complete cp genome of H. elliptica contains 129 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the cp genome is 38.1%. The phylogenetic analysis, based on 15 cp genomes, suggested that H. elliptica is closely related to Halenia corniculata (L.) Cornaz and Swertia species.
