The complete chloroplast genome sequence of Siphonostegia chinensis Benth. (Orobanchaceae)

Abstract

Siphonostegia chinensis Benth. is a common Chinese herbal medicine widely distributed in eastern Asia. The complete chloroplast genome of S. chinensis was newly sequenced in this study. The total chloroplast genome size was 148,961 bp, its structure and gene contents were well conserved as typical chloroplast characteristics. The overall guanine-cytosine (GC) content of the S. chinensis chloroplast genome is 36.4%. The chloroplast genome encodes 130 unique genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. We used the cp genome of S. chinensis and 20 other chloroplast genomes to perform a phylogenetic analysis, which indicated that S. chinensis is sister to Schwalbea americana in Orobanchaceae.
