Characterization of the complete chloroplast genome of Scrophularia cephalantha endemic to Korea

Abstract

Scrophularia species are highly valued and widely used traditional medicinal plants in East Asia. In this article, the complete chloroplast genome of Scrophularia cephalantha, a species endemic to South Korea, is reported for the first time. The genome is 153,016 bp long, and it is composed of a pair of 25,485 bp inverted repeats (IRs), separated by a large single copy (LSC) region of 84,124 bp, and a small single copy (SSC) region of 17,922 bp. There are 133 predicted genes in the genome, comprising 88 protein-coding genes, 37 tRNAs, and 8 rRNAs, with an overall GC content of 38%. Phylogenetic analysis based on the chloroplast genome data showed that S. cephalantha is a sister species to S. buergeriana and S. ningpoensis. The data provide useful molecular information for phylogenetic and evolutionary studies of the genus Scrophularia and its related species.
