The sequenced mitochondrial genome of the threatened alpine butterflyParnassius nomionincludes 13 protein-coding genes (ND1-6, COI-III, ATP6, ATP8, ND4, ND4L, CTYB), 2 ribosomalRNAs (12 Sand16 S), 22 transferRNAs, which is 14,547 bp in length. Its gene order and orientation are identical to the common type found in most of other completely sequenced lepidopteran mitogenomes. All protein-coding genes are initiated by ATN codons, except forCOI, which uses CGA as its start codon. Eleven PCGs use the standard TAA as their termination codon, andCOI, COIIuse the incomplete termination codon T. [ABSTRACT FROM AUTHOR]
