| 摘 要： | 近年来，分子系统发育分析方法，特别是rBNA基因同源性分析方法，在微生物多样性的研究中发挥着越来越重要的作用．它克服了传统的微生物分离培养方法的限制，极大地促进了人们对微生物多样性的理解．在遗传信息同源性分析基础上得出的微生物系统发育多样性为多样性的保护提供了新的视点．它不但可以作为微生物多样性评价的手段，而且为多样性保护中优先秩序的确定提供了依据．同时也为生物多样性保护确定了目标，即最大程度地保护系统发育关系中所包含的信息．本文对微生物系统发育多样性的特点及其保护生物学意义进行了简要评述．

| Abstract: | Molecular phylogenetic analysis plays a very important role in the study of microbial diversity. For both cultivated and uncultivated microbes, the comparative sequence analysis of 16S rRNA enabled the investigation of phylogenetic relationships among microorganisms in a manner that was not feasible through traditional microbiological methods. As a result, there are drastic revisions in our understanding of microbiology. The phylogenetic diversity based on the comparative sequence analysis of 16S rRNA produced new insights into the biodiversity conservation.It provides a method for biodiversity judgment and a guideline for biodiversity conservation. Also,it produces the aim of conservation,which is to keep the phylogenetic information as much as possible.In this review, some characters of microbial phylogenetic diversity and the perspectives in conservation biology are outlined. |
