Abstract

Saussurea inversa Raab-Straube is a small perennial and polycarpic herb that is distributed on the rocky slopes of the Qinghai-Tibetan plateau (QTP) at an altitude of 3700-5400 meters. It has a chloroplast genome structure similar to that of other species of Saussurea. It is 152,102 bp in size, including a large single-copy (LSC) region of 83,450 bp, a small single-copy (SSC) region of 18,286 bp and a pair of inverted repeats (IRs) of 25,183 bp. The chloroplast genome of S. inversa encodes 113 genes, containing 80 protein-coding genes (PCGs), 29 tRNA and four rRNA genes. Phylogenetic analysis shows that S. inversa is clustered with S. pseudosimpsoniana and S. laniceps.

Keywords: Saussurea inversa; chloroplast genome; phylogeny.
