Abstract

The complete mitochondrial genome of Pazala timur (Lepidoptera: Papilionodae) is a circular molecule of 15,226 bp in length, containing 37 typical animal mitochondrial genes: 13 protein coding genes, 2 rRNA genes, 22 tRNA genes and a non-coding AT-rich region. Its gene order and arrangement are identical to all other available butterfly mitogenomes. All PCGs initiate with typical ATN codons, except for COI, which is initiated by the CGA codon. Ten PCGs use complete termination codon (TAA), whereas the COI, COII and ND5 genes end with single T. Twelve intergenic spacers (82 bp in total), and 11 overlapping regions (30 bp in total) are dispersed throughout the whole genome. The non-coding AT-rich region is 403 bp long and contains some conserved structures characteristic of the butterfly mitogenomes, such as the motif ATAGA followed by a 13-bp poly-T stretch and a microsatellite-like (AT)12 element preceded by the ATTTA motif.

摘要

铁木剑凤蝶(鳞翅目:凤蝶科)的完整线粒体基因组是一个长度为15,226 bp的环状分子,包含37个典型的动物线粒体基因:13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个富含AT的非编码区。其基因顺序和排列与所有其他已有的蝴蝶线粒体基因组相同。所有蛋白质编码基因均以典型的ATN密码子起始,但细胞色素氧化酶亚基I(COI)以CGA密码子起始。10个蛋白质编码基因使用完整的终止密码子(TAA),而COI、细胞色素氧化酶亚基II(COII)和烟酰胺腺嘌呤二核苷酸脱氢酶亚基5(ND5)基因以单个T结尾。12个基因间隔区(共82 bp)和11个重叠区域(共30 bp)分散在整个基因组中。富含AT的非编码区长403 bp,包含一些蝴蝶线粒体基因组特有的保守结构,如基序ATAGA后接一个13 bp的多聚T序列,以及在ATTTA基序之前的类似微卫星的(AT)12元件。
