纤毛虫分子系统发育学的研究进展

Molecular Phylogeny of Ciliates

在回顾纤毛虫分子系统发育学产生发展历史的基础上 ,介绍了随后 2 0年中RFLP、RAPD和DNA序列分析等分子生物学技术作为该学科的主要研究方法在种群遗传多样性与进化、种上阶元系统发育学两方面取得的研究成果和近期研究进展 ,最后在探讨纤毛虫分子系统发育学存在的一些问题和解决方法的同时 ,预测了纤毛虫分子系统发育学今后将极大地推动真核生物的起源与进化、内共生等重要生物进化问题的研究。

Molecular phylogeny of ciliates started in the early 1980s. Its methods, such as RFLP(restriction fragment length polymorphism),RAPD(random amplified polymorphic DNA )and DNA sequences, and its contents including two main parts (genetic diversity of population, and phylogeny) were summarized. Its developments will bring about a great advance in the original and the evolution of eukaryote, and other evolutional focuses, such as endosymbiosis theory.
