在本研究中，首次报道了柞蚕Y6株(鳞翅目：土蛾科)的线粒体全基因组。它是一个环状分子，全长15,569个核苷酸，包含37个典型的编码基因和1个非编码的AT富集区。有丝分裂组的总组成为A(39.27%)、G(7.71%)、C(12.01%)和T(41.01%)。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，552bp的AT富集区还含有一些鳞翅目昆虫共有的结构，如重复模体和类微卫星元件的结构。系统发育分析表明，该菌株与天蚕科的亲缘关系较近。
In this study, the complete mitochondrial genome of Antheraea pernyi strain Yu6 (Lepidoptera: Saturniidae) has been reported for the first time. It is a circular molecule of 15,569 bp in length, containing 37 typical coding genes and 1 non-coding AT-rich region. The overall composition of the mitogenome is A (39.27%), G (7.71%), C (12.01%), and T (41.01%). 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 552 bp long AT-rich region contained several structures common to the other lepidopterons, such as some structures of repeated motifs and microsatellite-like elements. Phylogenetic analysis showed that the Antheraea pernyi Yu6 was close to Saturniidae.
