The characteristics and phylogenetic relationship of two complete mitochondrial genomes of Cottus pollux (scorpaeniformes: cottidae)

초록

We report two complete mitochondrial genomes of Cottus pollux based on specimens collected from Deokdong and Hoam Streams in the Republic of Korea. The two complete mitochondrial genomes were 16,558 and 16,557 bp long. Both contain the 37 standard genes (13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region) in the same order and have similar nucleotide compositions. According to the phylogenetic tree constructed using the maximum-likelihood method, C. pollux is closely related to C. reinii. The genetic information provided by the complete mitochondrial genome of C. pollux will contribute to an understanding of the phylogenetic position, evolutionary relationships, and biogeographical patterns of this species within the genus Cottus.
