本研究首次测定了天蚕731株(鳞翅目：天蚕科)的线粒体全基因组。它是一个环状分子，全长15,570个碱基，有37个典型的编码基因和一个非编码的富含T区。它的基因顺序和含量与大多数昆虫有丝分裂体中常见的类型相同。所有蛋白质编码基因(PCG)都以典型的ATN起始密码子开头，除了cox1基因，它以TTAG密码子开头。9个基因使用标准的完整终止密码子TAA，而cox1、cox2、nad3和nad5基因以单个T结尾，所有tRNA都像其他昆虫一样具有典型的次生三叶草结构。此外，AT富含非编码区全长553bp，位于RRN和trnM基因之间。它含有一些其他鳞翅目所特有的重复模体结构和微卫星样元素。系统发育分析表明，Antheraea pernyi 731与土蚕科的亲缘关系较近。
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.
