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

摘要

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 .
