Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Nov;27(6):4031-4032. doi: 10.3109/19401736.2014.1003829. Epub 2015 Jan 20.
The complete mitochondrial genome of Parnassius cephalus is 15,343 bp in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, 2 ribosomal RNA genes and a noncoding AT-rich region. All the 13 PCGs are initiated with the codon ATN, except for COI gene which starts with codon CGA. Eleven PCGs stop with the termination codon TAN, while the COI and COII genes end with single nucleotide T. All the tRNA genes have the typical secondary clover-leaf structures except tRNA, which loses its DHU stem. The two rRNA genes (lrRNA and srRNA) are 1341 bp and 777 bp in length, with their AT contents being 83.75% and 85.33%, respectively. The AT-rich region is 487 bp in length, and contains some conservative structures similar to other butterfly mitogenomes, such as a 17 bp poly-T stretch preceded by the ATAGA motif, and a microsatellite-like (AT) element preceded by the ATTTA motif.
红珠绢蝶的完整线粒体基因组长度为15343 bp，包含13个蛋白质编码基因（PCGs）、22个tRNA基因、2个核糖体RNA基因和一个富含AT的非编码区。13个PCGs均以ATN作为起始密码子，但细胞色素氧化酶亚基I（COI）基因以CGA作为起始密码子。11个PCGs以终止密码子TAN结束，而COI和细胞色素氧化酶亚基II（COII）基因以单个核苷酸T结束。除tRNA^Ser(AGN)外，所有tRNA基因均具有典型的二级三叶草结构，tRNA^Ser(AGN)失去了其DHU茎。两个rRNA基因（大核糖体RNA（lrRNA）和小核糖体RNA（srRNA））长度分别为1341 bp和777 bp，其AT含量分别为83.75%和85.33%。富含AT的区域长度为487 bp，包含一些与其他蝴蝶线粒体基因组相似的保守结构，如在ATAGA基序之前有一个17 bp的多聚T序列，以及在ATTTA基序之前有一个类似微卫星的（AT）元件。
