Abstract

Gentiana rigescens Franch. ex Hemsl. (Gentianaceae) is an endangered medicinal plant endemic to the southwest of China. The chloroplast (cp) genome of G. rigescens was 146,891 bp in length, with a large single-copy (LSC) region of 79,377 bp, a small single-copy (SSC) region of 17,026 bp, and a pair of inverted repeats (IRs) of 25,244 bp, forming a typical quadripartite structure. A total of 130 genes were annotated from the cp genome of G. rigescens, including 85 protein-coding genes, 37 tRNA genes, and 8 ribosomal RNA genes. Phylogenetic analysis indicated that G. rigescens was closely related to G. tonggolensis with strong bootstrap values belonging to the subfamily Gentianoideae.
