The complete mitochondrial genome of Chionodraco hamatus (Notothenioidei: Channichthyidae) with phylogenetic consideration.

ABSTRACT: The complete mitochondrial genome of Chionodraco hamatus was obtained, which was 17?457?bp in length. This genome consists of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and a putative control region. Of the 37 genes, 28 were encoded by heavy strand, while 9 were encoded by light strand. Overall base composition of mitogenome is estimated to be 26.38% for A, 17.44% for G, 26.00% for T, 30.18% for C, respectively, with a slight A?+?T bias (52.38%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested that C. hamatus as a sister species to Chionodraco myersi was clustered in family Chionodraco. The complete mitochondrial genome sequence of C. hamatus could provide a basic data for the studies on evolution for low temperature adaptability, population structure, molecular systematic, stock evaluation and conservation genetics.
