Complete mitochondrial genome of Trematomus newnesi (Perciformes, Nototheniidae)

Abstract

The complete mitochondrial genome ofTrematomus newnesiwas sequenced using an Illumina plat-form. The 18,602bp mitogenome contains 13 protein-coding genes, two rRNAs, and 23 tRNAs (tRNAMetis duplicated). The eight stop codons are TAA, TAG, CTT, GTA, AAT, ACT, AGG, and TTA. Two startcodons ATG and GTG are present. The GC content is 44.4% and AT content is 55.6%. A phylogenetictree was generated using 13 species from three families. The results showed thatT. newnesiis closelyrelated toPagothenia borchgrevinkiin Nototheniidae. This study provides fundamental data for furthergenetic evolutionary studies onT. newnesi.
