The complete chloroplast genome sequence of Gentianopsis grandis (Harry Sm.) Ma (Gentianaceae) and phylogenetic analysis.

The high-throughput sequencing technology was used to sequence and assemble the chloroplast genome of Gentianopsis grandis, and we analyzed its structural characteristics and phylogenetic relationships. The complete chloroplast genome of G. grandis was 151,271 bp in length, consisting of a large single copy (LSC) region of 82,572 bp and a small single copy (SSC) region of 17,907 bp, which were separated by a pair of inverted repeat regions (IRs) of 25,396 bp. The annotation contained a total of 114 unique genes, including 78 protein-coding genes, 30 tRNA genes, four rRNA genes, and two pseudogenes. The phylogenetic analysis indicated the genus Gentianopsis was closely related to Halenia and Swertia.
