我们测定了韩国毛条蛾（鳞翅目：Lycaenidae科）线粒体基因组（mitogenome）的全核苷酸序列。整个线粒体DNA （mtDNA）分子长15 314 bp。C. raphaelis基因的顺序和取向与其他鳞翅目物种完全测序的有丝分裂基因组相同，只是存在一个额外的tRNA(Ser)（AGN）拷贝。两个串联定位的tRNA(Ser)（AGN）拷贝之间的一级序列和二级结构高度相似，表明原始单个tRNA(Ser)（AGN）最近发生了重复。两个tRNA(Ser)（AGN）拷贝的东华大学臂形成了一个简单的环，与许多其他后生动物的tRNA(Ser)（AGN）一样。据推测，C. raphaelis COI基因的起始密码子似乎是一个四核苷酸TTAG，通常在鳞翅目动物中发现。ATPase8、ATPase6、ND4L和ND6基因在其3'端与另一个蛋白质编码基因相邻，它们都具有形成发夹结构的序列潜力，这表明这种结构对于成熟蛋白质编码基因的精确切割具有重要意义。
We determined the complete nucleotide sequences of the mitochondrial genome (mitogenome) of the Korean hairstreak, Coreana raphaelis (Lepidoptera: Lycaenidae). The entire mitochondrial DNA (mtDNA) molecule was 15 314 bp long. The C. raphaelis genes were in the same order and orientation as the completely sequenced mitogenomes of other lepidopteran species, except for the presence of an extra copy of tRNA(Ser)(AGN). High similarity in primary sequence and secondary structure between the two tandemly located copies of the tRNA(Ser)(AGN) suggest a recent duplication of an original single tRNA(Ser)(AGN). The DHU arm of the two copies of tRNA(Ser)(AGN) formed a simple loop as seen in many other metazoan mt tRNA(Ser)(AGN). The putative initiation codon for the C. raphaelis COI gene appears to be a tetranucleotide, TTAG, found commonly in the sequenced lepidopterans. ATPase8, ATPase6, ND4L and ND6 genes, which are next to another protein-coding gene at their 3' end all had the sequences potential to form a hairpin structure, suggesting the importance of such a structure for precise cleavage of the mature protein-coding genes.
