Two complete chloroplast genome sequences and intra-species diversity for Rehmannia glutinosa (Orobanchaceae)

Rehmannia glutinosa is a plant used as traditional medicine for its various tonic effects in Korea and China. In this study, chloroplast genomes of two R. glutinosa were completed by de novo assembly using whole-genome Illumina sequence data. The length of chloroplast genomes of R. glutinosa collected from China and Korea was 153,680 bp and 153,499 bp, respectively. A total of 114 coding regions were predicted in both R. glutinosa including 80 protein-coding genes, 4 rRNA genes, and 30 tRNA genes. We identified abundant intra-species diversity of 87 InDels and 147 SNPs, among three R. glutinosa chloroplast genome sequences including one from GenBank. The phylogenetic analysis showed that these R. glutinosa were closely clustered with related Rehmannia species, separated from other Orobanchaceae and Scrophulariaceae species.
