The complete mitochondrial genome of Gadus chalcogramma and phylogenetic analysis

Abstract

Here, we report the complete mitochondrial genome sequence of Alaska Pollock, Gadus chalcogramma. The genome sequence was obtained via long PCR reactions using universal primer sets for the fish mitochondrial genome. The total length of mitochondrial genome was 16,571 bp, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and one control region (D-loop). Except for ND6 and eight tRNA genes, all of the other mitochondrial genes were encoded on the heavy strand. The NJ tree of the combined 13 protein-coding gene sequences of Gadus chalcogramma possesses a relatively closer relationship with the Okhotsk Sea Pollock (Gadus chalcogrammus). Our complete mitochondrial genome will be valuable resources for phylogeny, genetics, and conservation of the Gadus chalcogramma in Korea.
