In this study, the complete mitochondrial genome sequence of Bombyx mori strain Chunyun (Lepidoptera: Bombycidae) has been reported for the first time. The total length of the mitogenome was 15,659 bp with 37 typical animal mitochondrial genes and 1 non-coding A + T-rich region. Its gene content and order were identical to those of other lepidopteran mitochondrial genomes. All protein-coding genes (PCGs) were initiated by ATN codons except for the COI gene, which began with CGA codon. Eleven PCGs stopped with termination codon TAA, whereas the COI and COII genes ended with single T. All tRNAs have typical structures of insect mitochondrial tRNAs. The 494 bp AT-rich region contains several features common to other lepidopterans, such as some structures of repeated motifs and microsatellite-like elements and a poly-A element upstream of transfer RNA M (trnM) gene.
在本研究中，首次报道了家蚕春云品系（鳞翅目：蚕蛾科）的完整线粒体基因组序列。线粒体基因组全长15659bp，包含37个典型的动物线粒体基因和1个非编码的富含A+T区域。其基因内容和顺序与其他鳞翅目昆虫的线粒体基因组相同。除COI基因起始密码子为CGA外，所有蛋白质编码基因（PCGs）均由ATN密码子起始。11个PCGs以终止密码子TAA终止，而COI和COII基因以单个T结尾。所有tRNA都具有昆虫线粒体tRNA的典型结构。494bp的富含A区域包含其他鳞翅目昆虫共有的几个特征，如一些重复基序和微卫星样元件的结构以及转移RNA M（trnM）基因上游的一个多聚A元件。
