The complete mitochondrial genome of Antheraea pernyi strain 731 (Lepidoptera: Saturniidae).

In this study, the complete mitochondrial genome of Antheraea pernyi strain 731 (Lepidoptera: Saturniidae) is determined for the first time. It is a circular molecule of 15,570 bp in length, with 37 typical coding genes and one non-coding A T-rich region. Its gene order and content are identical to the common type found in most insect mitogenomes. All protein-coding genes (PCGs) start with a typical ATN initiation codon, except for the cox1 gene, which begins with TTAG codon. Nine genes used standard complete termination codon TAA, whereas the cox1, cox2, nad3, and nad5 genes end with single T. All tRNAs display typical secondary cloverleaf structures as those of other insects. Additionally, the non-coding AT-rich region is 553 bp long, located between rrnS and trnM genes. It contains some structures of repeated motifs and microsatellite-like elements characteristic of the other lepidopterons. Phylogenetic analysis showed that the Antheraea pernyi 731 was close to Saturniidae.
