The mitochondrial genome of Antheraea pernyi 2. Comparative mitogenomics between domestic and wild A. pernyi 线粒体（图1）是细胞的动力工厂。Mt DNA是第2遗传系统，呈母性遗传。 动物mtDNA是双链环状DNA分子，一般含有37个基因（13个蛋白编码基因、22个tRNA基因、2个rRNA基因）。 线粒体基因和基因组已经广泛应用于分子进化研究，包括系统发育和种群结构研究。 Animal mtDNA is a circular DNA molecule presenting a conserved set of 37 genes: 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The control region is also known as the A+T-rich region in insects. The mito genes and genomes have been widely used as an informative molecular marker for diverse evolutionary studies of animals, including phylogenetics and population genetics. 1. 柞蚕线粒体基因组的特征 The mitochondrial genome of Antheraea pernyi 图1 线粒体模式图 Fig.1 Module map of the mitochondria 鳞翅目是昆虫中仅次于鞘翅目的第2大目。最近，人们对鳞翅目昆虫线粒体基因组的序列测定投入了极大的兴趣。 目前，公共数据库中可以利用的鳞翅目昆虫线粒体基因组全序列有11个，其中有5个来自于蚕丝昆虫包括蚕蛾科的家蚕、中国野桑蚕、日本野桑蚕和大蚕蛾科的合目大蚕蛾、柞蚕。 测定新的蚕类昆虫线粒体基因组可以为我们理解蚕类昆虫线粒体基因组的多样性和进化提供更深入的帮助。 There has been a recent interest in mitogenome sequencing within Lepidoptera, which represents the second only to Coleoptera biodiversity in insects. To date, eleven complete mitogenomes have been currently available in the GenBank for lepidopterans, of which 5 complete mitogenomes are from silkworms (3 Bombycidae and 2 Saturniidae). Newly added silkworm mitogenomes can provide further insight into our understanding of insect mitogenome diversity and evolution. 1. 柞蚕线粒体基因组的特征 The mitochondrial genome o
