The complete mitochondrial genome of Gobionotothen gibberifrons (Perciformes, Nototheniidae)

Abstract

AbstractThe humped rockcod, Gobionotothen gibberifrons, is an Antarctic fish of the genus Gobionotothen in the family Nototheniidae and order Perciformes. To date, little biological information has been recorded about the genus Gobionotothen. Here, we report the first complete mitogenome of the genus Gobionotothen. The mitochondrial genome of G. gibberifrons is 18,631 bp in length, comprising 13 protein-coding genes, 24 tRNA genes (trnP-UGG and trnT-UGU were duplicated), 2 rRNA genes, and non-coding control regions. The base composition was 53.74% for A + T and 46.26% for G + C. This new mitochondrial genome of G. gibberifrons provides basic information for further phylogenetic analysis, suggesting the necessity to exploit a variety of newly discovered mitogenome sequences to infer inconclusive evolutionary relationships in Antarctic fishes.
