Comparative chloroplast genome analyses of 23 species in Swertia L. (Gentianaceae) with implications for its phylogeny.

ABSTRACT: Swertia L. is a large genus in the family Gentianaceae. Different chloroplast gene segments have been used to study systematic evolutionary relationships between species of Swertia L. However, as gene fragment-based phylogenies lack sufficient resolution, the systematic evolutionary relationships between Swertia L. species have remained unclear. We sequenced and annotated the complete chloroplast genomes of four Swertia species, namely, S. bifolia, S. tetraptera, S. franchetian, and S. przewalskii, using next generation sequencing and the plastid genome annotator tool. The chloroplast genome sequences of 19 additional species of Swertia L. were downloaded from the NCBI database and also assessed. We found that all 23 Swertia
