Complete chloroplast genome of Rorippa apetala Y.Y. Kim & B.U. Oh (Brassicales: Brassicaceae), a species endemic to the Korean Peninsula

Abstract

Here, we successfully assembled the complete chloroplast genome of Rorippa apetala Y.Y. Kim & B.U. Oh, a species endemic to the Korean Peninsula. The chloroplast genome was 154,818 bp long and exhibited a typical quadripartite structure comprising large single-copy (83,847 bp) and small single-copy (18,023 bp) regions, and a pair of inverted repeats (26,474 bp each). A total of 129 genes were encoded, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on the concatenated sequences of 78 protein-coding genes from 25 species revealed a close relationship between R. apetala and Rorippa indica (L.) Hiern, supported by full bootstrap value (100). Future studies employing more informative markers and a broader range of taxa will provide valuable insights into the biogeographical distribution of the genus Rorippa and offer a deeper understanding of the speciation process in R. apetala.
