Characterization of the complete chloroplast genome of a well-known Chinese medicinal herb, Scrophularia ningpoensis

Abstract

Scrophularia ningpoensis has been used as a famous traditional medicinal herb in Asian countries to treat jaundice, dysentery, and the pain of rheumatism. In this paper, the complete chloroplast (cp) genome sequence of S. ningpoensis was reported and characterized. The cp genome is 153,175 bp in length, composed of a pair of 25,490 bp inverted repeat (IR) regions separated by a large single copy (LSC) region of 84,257 bp and a small single copy (SSC) region of 17,938 bp. There were 130 predicted genes (85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes) in the genome, and the overall GC content of the genome is 38%. Phylogenetic analysis based on the cp genome data showed that S. ningpoensis was sister to S. buergeriana.
