摘要
Antarctic icefish Chionodraco hamatus is an ideal model for studying cold adaptation mechanisms. The complete mitochondrial genome of C. hamatus was sequenced in this study. The genome sequence is 17 373 bp in length, which comprises 13 protein-coding genes, 22 tRNAs, two rRNAs and a control region. The overall base composition is A: 26.25%, T: 26.05%, G: 17.49% and C: 30.21%, with an A: T content of 52.3%. The phylogenetic analyses based on the concatenated nucleotide sequences of all the genes and control region supported a relatively close relationship with Parachaenichthys. charcoti. The complete mitochondrial genome sequence will be useful for evolutionary and functional studies of Antarctic Notothenioids.
