摘要
相似的形态和高度的遗传多样性给昆虫的系统发育研究带来了难题。为了解决这些问题，基于线粒体的标记被采用并越来越多地用作分子标记用于系统发育研究。不同种类的昆虫使用了不同的标记，即16S r RNA、12S r RNA、ND(1-6基因)、atp酶和控制区的标记。在蛋白质编码基因中，CO-1因其优于其他基因而被认为是最好的，而线粒体DNA的AT富区是使用最少的标记。系统发育分析的新进展即有丝分裂基因组学极大地改善了这一研究领域。本文就线粒体分子标记在昆虫系统发育研究中的应用作一综述。
Mitochondrial markers for identification and phylogenetic studies in insects - A Review
Similar morphology and high genetic diversity poses problems in phylogenetic studies of insects. To solve these problems, mitochondrial based markers have been adopted and are increasingly used as molecular markers for phylogenetic studies. Varied markers have been used for different species of insects, viz., markers for 16S r RNA, 12S r RNA, ND (1-6 genes), ATPase and control regions. Among which protein coding gene, CO-1 is found to be best because of its advantage over others whereas, AT rich region of mitochondrial DNA is the least used marker. A recent advanced technology in phylogenetic analysis; namely mitogenomics have greatly improved this research field. This short review attempted to summarize recent studies on the application of vari ous mitochondrial molecular markers for phylogenetic study of insects.
