Circular map of the Trichiurus japonicus mitochondrial genome (16,796 bp). Protein-coding genes are color-coded by respiratory complex: Complex I (yellow), Complex IV (pink), ATP synthase (green), and other genes (purple). Transfer RNAs (blue) and ribosomal RNAs (red) were also shown here. The inner grey ring represented the GC content calculated in 4-bp sliding windows.
