原生动物AQPs系统进化树的构建以及结构分析

Construction and analysis of phylogenetic tree of protozoan AQPs system

文章应用Mega7,DNAMAN6等生物信息学软件,以检索并经过筛选的原生动物的AQPs为基础构建系统进化树,明确原生动物在进化中的亲缘关系,并找出聚类在一起的原生动物AQPs中的特异性序列。结果表明,70个原生动物AQPs聚类成4个大簇。聚成的4簇刚好覆盖原生动物门的4个纲,但是4个纲在特异性序列上并不完全相同,这为进一步研究AQPs的结构、分类及进行进一步比对和特异性功能预测提供基础依据。

Mega7、DNAMAN 6 software are applied to build protozoa AQPs phylogenetic tree and identify the evolution relationship in protozoa AQPs to identify AQPs specific sequence of the different clusters in the phylogenetic tree.The results show that 70 AQPs in evolutionary tree are clustered into the four major clusters,which just covers the four classes of the protozoa,but the four classes are not exactly the same in the specific sequence.This research provides the basic data for the further study of the structure,classification,further comparison and prediction of specific function of AQPs.
