Abstract

Gentianopsis paludosa (Hook. f.) Ma (Gentianaceae) is one of the genuine medicinal materials in Qinghai-Tibet Plateau, China. Here we report the first chloroplast (cp) genome of G. paludosa using Illumina NovaSeq 6000 platform. The length of its complete cp genome is 151,568 bp, containing four sub-regions; a large single copy region (LSC) of 82,834 bp and a small single copy region (SSC) of 17,928 bp are separated by a pair of inverted repeat regions (IRs) of 25,403bp. The complete cp genome of G. paludosa contains 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the cp genome is 37.8%. The phylogenetic analysis, based on 23 cp genomes, suggested that G. paludosa is closely related to G. grandis (H. Smith) Ma and Swertia species.

Keywords: Gentianaceae; Gentianopsis paludosa; Qinghai-Tibet Plateau; chloroplast genome; phylogenetic trees.
