Complete mitochondrial genome of the Antarctic silverfish, Pleuragramma antarcticum(Perciformes, Nototheniidae)

Abstract

The complete sequence of the mitochondrial genome of Pleuragramma antarcticum was obtained from the assembled genome data. The complete sequence was determined to be 18,460 bp in length, containing 13 protein coding genes, 22 tRNA genes, 2 rRNA genes, 2 control regions and a repeat. The general order and contents of the genes are identical with those of other fishes. The Antarctic notothenioid-specific translocation of ND6/tRNAGlu exists in the mitogenome. Pleuragramma antarcticum is the only pelagic species which dominates Antarctic fish fauna by more than 90%. Thus, the whole mitogenome sequences of P. antarcticum will provide the basis to understand the deep phylogeny of the Antarctic species.
