The complete chloroplast genome and phylogenetic analysis of Gentiana arethusae Burkill (Gentianaceae) from China

Abstract

Gentiana arethusae Burkill is a perennial herb classified in the Gentianaceae. In this study, the complete chloroplast genome of G. arethusae was sequenced and analyzed. The chloroplast genome is 137,458 bp in length and encodes a total of 116 genes, including 71 protein-coding, 37 tRNA, and eight rRNA genes. The genome has a low GC content of 38.0%. Phylogenetic analysis of the genome of G. arethusae resolved it in a clade with Gentiana obconica and Gentiana veitchiorum. The complete chloroplast genome of G. arethusae will be helpful to study the genetic diversity and phylogenetics of the Gentianaceae.
