The complete chloroplast genome sequence of an Alpine flowering plant Kuepferia otophora (Gentianaceae)

The complete chloroplast genome sequence of Kuepferia otophora, a flowering plant occurring in Hengduan Mountains with high altitudes, is determined in this study. The plastome is 139,684 bp in length, with one large single-copy region of 76,787 bp, one small single-copy region of 16,635 bp, and two inverted repeat (IR) regions of 23,131 bp. It contains 128 genes, including 83 protein-coding, 8 ribosomal RNA, and 37 transfer RNA genes. Phylogenetic tree shows that this species is a sister to the clade of genus Gentiana. The first published plastome within Kuepferia provides significant insight for elucidating the phylogenetic relationship of taxa within tribe Gentianeae.
