Characterization of the complete chloroplast genome of Swertia souliei (Gentianaceae)

摘要

The complete chloroplast genome sequence of Swertia souliei , an alpine annual herbaceous plant endemic to the Qinghai-Tibetan Plateau (QTP), is reported in this study. The plastome is 152,804?bp in length, with one large single-copy region of 83,195?bp, one small single-copy region of 18,096?bp, and two inverted repeat (IR) regions of 25,756?bp. It contains 130 genes, including 85 protein-coding, 8 ribosomal RNA, and 37 transfer RNA genes. Phylogenetic tree shows that this species is a sister to the clade containing S. leducii, S. verticillifolia , and S. mussotii . The complete chloroplast genome could provide significant insight for understanding the phylogenetic relationship of taxa within Gentianaceae.
