摘要:

本文综述了与分子系统学发展密切相关的4个因素:1.分子生物学方法的不断改进;2.基因组的全序列测定;3.用于分子系统学研究的基因种类不断增加,对这些基因进化规律的认识不断深入;4.化石DNA的研究。本文还阐述了核基因及叶绿体基因在系统学研究中的应用,例举了rbcL、matk、18s rDNA和ITS序列分析在植物系统发育研究中取得的重要成果,同时提出了分子系统学研究中应注意的一些问题。

关键词: 分子系统学, 评述

Abstract:

Reviewed in the present paper are four most important factors stimulating the development of molecular systematics: improvement of molecular biological methods, complete sequencing of genome, recognition of evolution rules of increasing number of genes widely used in molecular systematics, and study of fossil DNA. Systematic importance of both nuclear genes and chloroplast genes is discussed. In addition, some exciting results in molecular
phylogeny constructed from sequence analyses of rbcL, matK, 18s rDNA and ITS are enumerated respectively. Moreover, the authors put forward some problems needing attention in molecular systematic study.
