摘要
对mt基因组的比较研究是探讨节肢动物系统发生的有效手段之一。基因的排列和DNA序列可以为重建节肢动物的系统发生提供有用的信息。目前 ,已测定mt基因组全序列的节肢动物已增加到 4 4种。归纳、总结了节肢动物mt基因组的基本特征、基因顺序、基因重排的发生和机制等。简要评述基于mt基因组的节肢动物系统发生研究。
Among the effective techniques for exploring the phylogeny of arthropods,the comparison of the whole of mt genomes can provide useful information from two aspects for reconstructing phylogenetic relationships among arthropod groups,one is gene arrangement,and the other is DNA sequence.The number of complete mitochondrial genomes of arthropod species studied has been increased to 44.In this article we attempt to summarize the basic features of mt genome,the gene order,the occurrence of mt gene rearrangements and the mechanism of gene rearrangement of arthropods,etc.,and make a brief review for the recent progress and perspective in the researches of arthropod phylogeny based on mt genome.
