Characterization of the complete chloroplast genome of Saussurea integrifolia (Compositae)

Abstract

The complete chloroplast genome sequence of Saussurea integrifolia, a flowering plant occurring in Hengduan Mountains with high altitudes, is determined in this study. The plastome is 152,584 bp in length, with one large single-copy region of 83,497 bp, one small single-copy region of 18,646 bp, and two inverted repeat (IR) regions of 25,221 bp. It contains 123 genes, including 86 protein-coding genes, 8 ribosomal RNA, and 36 transfer RNA. Phylogenetic tree shows that this species is a sister to Arctium lappa. The published plastome within Saussurea provides significant insight for elucidating the phylogenetic relationship of taxa within tribe Compositae.
