三种萤火虫的线粒体基因组测序和18种甲虫的系统发育分析
Mitochondrial genome sequencing of three firefly beetles and phylogenetic analysis of 18 species of beetles
为了验证基于二代测序获得的转录组数据的系统发育推断,利用传统的一代测序获得了黄缘萤(Aquatic ficta)和武汉萤(Aquatic wuhana)的线粒体基因组全序列和云南扁萤(Lamprigera yunnana)的线粒体基因组接近全序列;从4种发光甲虫的转录组序列中查找到所有的线粒体编码基因序列;再从公共数据库中提取了12种近源甲虫的线粒体基因组全序列。由于黄缘萤的线粒体基因组序列同时有一代和二代测序的数据,本研究共分析了18种甲虫的线粒体基因组序列。对所有甲虫的线粒体编码序列进行对位排列后,利用最大似然法和贝叶斯推断的方法,将18种甲虫的线粒体数据进行系统发育重建。结果显示,雌光萤与萤科的萤火虫具有显著不同的系统位置,支持将雌光萤独立成一个科,与之前的转录组分析结果一致。因此,该研究不仅提供了新的线粒体全序列数据,将为未来的系统发育分析提供数据,同时也指出了使用线粒体基因和核基因进行综合分析对系统发育研究的重要性。
o validate the phylogenetic inference based on transcriptome data, we employed the traditional Sanger sequencing to obtain two complete mitogenomes (Aquatica ficta and A. wuhana) and one nearly complete mitogenome (Lamprigera yunnana); we also identified the 13 protein coding genes (PCGs) in mitogenomes from each of the four whole-body transcriptomes; and we additionally retrieved 12 published complete mitogenomes from members of Rhagophthalmidae, Lampyridae, Phengodidae, Elateridae, Lycidae, Cantharidae, and Tenebrionidae. Our mitogenome analysis confirmed the distinctiveness of Rhagophthalmidae from Lampyridae, which is consistent to our earlier transcriptome analysis.
