Abstract

The complete mitochondrial genome of Trematomus loennbergii was studied using NGS technology with PacBio platform. The mitochondrial genome size was 19,374bp and it had 13 protein-coding genes, 22 tRNAs and 2 rRNAs. There were 4 types of stop codons which were TAA, TAG, AGG and T(AA) but start codon type was only one (ATG). The contents of GC were 44.09% and AT contents were 55.91%. To conduct phylogenetic analysis, 12 species in 3 families were used. The result suggested that T. loennbergii was close to Pagothenia borchgrevinki in Nototheniidae. This study would provide a fundamental data for molecular evolution of T. loennbergii.
