Abstract

The complete mitochondrial genome of Trematomus newnesi was sequenced using an Illumina platform. The 18,602 bp mitogenome contains 13 protein-coding genes, two rRNAs, and 23 tRNAs (tRNA^Met is duplicated). The eight stop codons are TAA, TAG, CTT, GTA, AAT, ACT, AGG, and TTA. Two start codons ATG and GTG are present. The GC content is 44.4% and AT content is 55.6%. A phylogenetic tree was generated using 13 species from three families. The results showed that T. newnesi is closely related to Pagothenia borchgrevinki in Nototheniidae. This study provides fundamental data for further genetic evolutionary studies on T. newnesi.
