Abstract

Rana coreana is a brown frog species native to the Korean Peninsula. We characterized the complete mitochondrial genome of the species. The mitochondrial genome sequence of R. coreana is 22,262 bp and comprises 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and two control regions (CRs). The CR duplication and gene organization were identical to those observed in Rana kunyuensis and Rana amurensis. A total of 13 protein-coding genes were used to examine the phylogenetic relationships between this species and the genus Rana. R. coreana living on the Korean Peninsula, formed a cluster with R. kunyuensis and R. amurensis, with R. coreana showing the closest phylogenetic affinity for R. kunyuensis.

Keywords: CR duplication; Rana coreana; brown frog; mitochondrial genome.

Rana coreana specimen. Rana coreana is a brown frog found in South Korea. This species differs from other brown frogs in having a continuous white line along its upper lip, as shown in the figure. Photograph was taken of National Institute of Biological Resources (NIBR) immersion specimens (NIBR AM0000000711).
