The mitochondrial genome of the butterfly Papilio xuthus (Lepidoptera: Papilionidae) and related phylogenetic analyses

摘要: The nearly complete mitochondrial genome of the butterfly Papilio xuthus (Lepidoptera: Papilionidae) was sequenced for its nucleotide sequence 13,964 bp. has a typical gene order identical to other lepidopteran species. All tRNAs showed same stable canonical clover-leaf structure as those insects, except tRNASer (AGN), in which dihydrouracil arm (DHU arm) could not form stem–loop structure. Anomalous initiation codons have been observed cox1 gene, where ATTACG hexa-nucleotide believed be involved signaling. Twelve protein-coding data were used infer phylogenetic relationships among insect orders. Even though number orders represented by genomes is still limited, several well-established are evident analysis sequences. Monophyly Homometabola supported this paper. Phylogenetic analyses available species Bombycoidea, Pyraloidea, Papilionoidea and Tortricidea bolstered current morphology-based hypothesis that Pyraloidea monophyletic (Obtectomera). Bombycoidea (Bombyx mandarina Antheraea pernyi) (P. Coreana raphaelis) formed sister group.
