Characterization of complete mitochondrial genome of Pogonophryne albipinna (Perciformes: Artedidraconidae)

Abstract

The complete mitochondrial genome of Pogonophryne albipinna was determined by the MiSeq platform, which was the first report in the family Artedidraconidae. The circular form of its mitochondrial genome was 17,086 bp, which contained the canonical eukaryotic 37 genes. The gene orders of P. albipinna was identical to the other icefish species, in which there was additional non-coding region and translocation of ND6 gene. Except for ATP6 gene and COI (GTG), 11 genes begin with the typical start codon, while incomplete stop codons (T– –) were identified in COII, ND4, and CytB. Phylogenetic tree with the currently known mitogenomes in suborder Notothenioidei showed that P. albipinna was located distinctly from those in Bathydraconidae and Nototheniidae forming a unique cluster as Artedidraconidae. The first complete mitochondrial genome of P. albipinna would be the fundamental data to understand the evolutional relationship of icefish species in the Antarctic Oceans.
