Complete mitochondrial genome of the Antarctic dragonfish, Parachaenichthys charcoti (Notothenioidei: Bathydraconidae)

Abstract

The complete mitochondrial genome of the Antarctic dragonfish, Parachaenichthys charcoti (Vaillant, 1906), is described, representing the first complete mitochondrial genome sequence of the family Bathydraconidae. The mitochondrial genome is 18,202 base pairs in length and encodes 13 protein-coding genes, 23 tRNAs, 2 rRNAs and 2 control regions. The overall base composition is A: 25.8%, T: 25.3%, G: 17.9% and C: 31.0%, with an A:T content of 51.1%. The complete mitochondrial genome sequence will be useful for phylogenetic, evolutionary and functional studies of Antarctic Notothenioids.
