基于12S rRNA和16S rRNA基因序列探讨中国蚤蝇科部分属间的系统发育关系

Phylogenetic Relationships among Some Chinese Genera of Phoridae Based on Mitochondrial 12S and 16S rRNA Gene Sequences

  • 摘要: 基于线粒体12S rRNA和16S rRNA基因序列联合分析,采用最大简约法、最大似然法和贝叶斯法分别构建了中国蚤蝇科14属的系统发育树。结果表明:联合分析序列总长度为819 bp,其中可变位点277个,简约信息位点200个;A+T平均含量为77.7%,具A、T偏倚性。系统发育分析显示,中国蚤蝇科为单系发生,分为蚤蝇亚科和裂蚤蝇亚科两个单系群。蚤蝇亚科内脉蚤蝇属、锥蚤蝇属和刺蚤蝇属亲缘关系较近,栅蚤蝇属与栓蚤蝇属亲缘关系较近;裂蚤蝇亚科中虼蚤蝇属与裂蚤蝇属互为姐妹群,寡蚤蝇属与伐蚤蝇属互为姐妹群。

     

    Abstract: The phylogenetic relationships among 14 Chinese genera of Phoridae were reconstructed based on concatenated sequences of the mitochondrial 12S and 16S rRNA genes using maximum parsimony, maximum likelihood and Bayesian methods. The alignment of the concatenated sequences spanned 819 sites including 277 variable sites, of which 200 were parsimony-informative. The sequences showed a 77.7% A+T bias. The phylogenetic analysis showed that the Phoridae was monophyletic. It was shown that the involved genera in the study clustered into monophyletic Phorinae and Metopininae. The genera Diplonevra and Dohrniphora were closely related to each other. The relationships among Anevrina, Conicera and Spiniphora were also closer. The genera Metopina and Puliciphora proved to be reciprocal sister group and the cluster analysis showed the close relationship between Gymnophora and Phalacrotophora.
