The complete mitochondrial genome of Pagetopsis macropterus (Notothenioidei: Channichthyidae) with phylogenetic consideration

Abstract

In this study, the complete mitochondrial genome of Pagetopsis macropterus was obtained, which was 17,342 bp including 2 ribosomal RNAs, 13 protein-coding genes, 22 transfer RNAs, and one control region. Of the 37 genes, 28 were encoded on the heavy strand, while 9 were encoded on light strand. The overall nucleotide composition of mitogenome is 27.08% for A, 25.75% for T, 29.78% for C, 17.39% for G, respectively, in accordance with structural characteristics of AT rich. Further, the phylogenetic tree based on complete mtDNA sequences revealed that the P. macropterus was closest to some species of Channichthyidae. This study could provide some valuable information for the studies on evolution for low-temperature adaptability, stock evaluation, and population genetics of P. macropterus.
