The complete chloroplast genome of Sauvagesia rhodoleuca, an endangered species endemic to China

Abstract

Sauvagesia rhodoleuca is an endangered and national key protected species of China, with limited natural distribution in Guangdong and Guangxi, Southern China. Here we reported the first complete chloroplast genome of S. rhodoleuca using genome skimming approach. The chloroplast genome is 157,300 bp in length, with a large single-copy region (LSC) of 86,021 bp and a small single-copy region (SSC) of 18,137 bp separated by a pair of inverted repeats (IRs) of 26,571 bp. It encodes 112 unique genes, including 80 protein-coding genes, 28 transfer RNA genes, and four ribosomal RNA genes. Phylogenetic analysis results strongly supported that S. rhodoleuca was closely related to Medusagyne oppositifolia.
