昆虫线粒体基因组重排的研究进展

Rearrangement of mitochondrial genome in insects

动物线粒体基因组通常组成稳定,基因排列也相对保守,极少发生重组。但是昆虫的线粒体基因组具有重排的可能性,而且这些重排事件可能为系统发育研究提供重要的信息。因此,深入研究昆虫线粒体基因组的重排可能有助于解决具有争议的系统发生关系。本文对昆虫线粒体基因组的重排类型、重排机理和重排在昆虫系统发育分析中的应用等方面的研究进展进行了介绍。

Generally,animal mitochondrial genomes have stable gene content,relatively conserved gene arrangement and infrequent recombination. However,insect mitochondrial genomes have the potential of rearrangement,which might provide important information for phylogenetic studies,and further study into this tool may contribute to resolving the debatable phylogeny. This paper reviewed progress in this field,including types,mechanisms of gene rearrangement in insects and its utilization in phylogenetic analysis.
