测定了中国云南禄丰裂眼甲（Rhagophthalmus lufengensis）和日本八重山岛大白裂眼甲（Rhagophthalmus ohbai）的线粒体MA（mtDNA）序列。我们鉴定了所有的37个线粒体基因。lufengensis（15，982 bp）和R. Ohbai（15，704bp）。R. lufengensis和R.虽然基因排列相似，但大羽基因组的A + T含量高于其他鞘翅目基因组。有趣的是，在一项关于R. lufengensis、鲁丰河（R. ohbai和萤火虫Pyrocoelia rufa的线粒体基因组IrRNA基因构建的系统发育树表明东亚生物发光昆虫之间存在亲缘关系，而核基因组DNA酶相关基因构建的系统发育树表明鞘翅目昆虫之间存在适当的亲缘关系，反映了生物发光的进化起源。因此，发光甲虫的mtDNA可以提供一个洞察他们的进化起源和地理。(c)2006 Elsevier B.V.保留所有权利。
We determined the mitochondrial MA (mtDNA) sequences of two luminous beetles (Arthropoda, Insecta, Coleoptera), Rhagophthalmus lufengensis from Yunnan, China and Rhagophthalmus ohbai from Yaeyama Island, Japan. We identified all the 37 mtDNA genes of R. lufengensis (15,982 bp) and the 34 genes of R. ohbai (15,704 bp). R. lufengensis and R. ohbai genomes have higher A + T contents than other coleopteran genomes although the gene arrangements are similar. Interestingly, in a study of the evolutionary relationship among R. lufengensis, R. ohbai and the firefly Pyrocoelia rufa, the phylogenetic tree inferred from IrRNA genes from mitochondrial genomes indicates a biogeographic relationship among the bioluminescent insects in East Asia and the phylogenetic tree inferred from luciferase-related genes from nuclear genomes shows an appropriate relationship among coleopterans, reflecting the evolutionary origin of bioluminescence. Thus, the mtDNAs of luminescent beetles can provide an insight into their evolutionary origin and biogeography. (c) 2006 Elsevier B.V. All rights reserved..
