摘要
后生动物线粒体基因组由于其大小和基因数目的相对稳定,被认为是研究后生动物系统发育关系的一种理想模型。后生动物线粒体基因组大多有37个基因,包括22个tRNA编码基因和13个蛋白编码基因,它们的排列顺序也被认为是研究后生动物线粒体基因组很好的材料。通过对来自NCBI数据库的2 511种后生动物线粒体基因组提取的基因次序,包括对基因的倒置、共有基因簇、基因的缺失和重复、相邻位置的基因交换等重组形式的概述,综述了近年来对动物线粒体基因组基因次序重组的研究状况。
Typical Metazoa mitochondrion genome contains 37 genes： 2 for rRNA, 13 for protein coding genes and 22 for tRNA. Rearrangement of mitochondrial gene orders constitutes an ideal model for studying phylogenetic investigation. In this paper, we downloaded 2 511 Mmetazoa mitochondrion genomes from NCBI database, and se lected their gene orders with perl scripts. The rearrangement of gene orders was summarized from five aspects, including the gene reverse, gene reversions, gene lost and duplicate, share clusters and transitions. The progresses of Metazoa mitochondrial gene order rearrangement in recent years were also reviewed. Many classical rearrangement patterns were proved in gene order comparisons among different species categories, and the relationships between phylogeny and mitochondrial gene order rearrangement were revealed.
