Complete mitochondrial genome of the Small Salamander in Korea, Hynobius unisacculus (Anura: Hynobiidae).

The complete mitochondrial (mt) genome of Hynobius unisacculus was sequenced and characterized. The circular mt genome constituted of 37 genes (13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs) and a non-coding region (NCR). Phylogenetic analysis based on the full mt genome sequences confirmed that H. unisacculus was closely related to Hynobius leechii rather than other Hynobius species. This is the first completed mt genome from H. unisacculus, which provides data for further study of phylogeny in Hynobiidaes.

Complete mitochondrial genome of the American bullfrog in Korea, Lithobates catesbeianus (Anura: Ranidae).

The complete mitochondrial (mt) genome of Lithobates catesbeianus was sequenced and characterized. The circular mt genome was constituted of of 37 genes (13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs) and a non-coding region (NCR). Phylogenetic analysis based on the full mt genome sequences confirmed that among the genus Lithobates, L. catesbeianus Korea is included in a monophyletic group with L. catesbeianus China, but not with either L. catesbeianus Japan or L. catesbeianus Canada. This is the first completed mt genome from L. catesbeianus Korea, which provide data for further study of phylogeny in Lithobates spp. that have been introduced into a number of different countries originally from North America.
