【摘要】 遗传多样性作为多相分类的主要手段,在根瘤菌的分类和多样性研究中备受关注.随着根瘤菌寄主研究范围的不断扩大和分子生物学技术的不断应用,根瘤菌的遗传多样性特征将得到更深入的揭示.本文综述了根瘤菌遗传多样性的组成、研究现状及研究方法进展,以期为细菌分类工作者提供一定的研究依据.更多还原

【Abstract】 As a major means of polyphasic taxonomy,genetic diversity was concerned recently.With the enlargement of rhizobial host research scope and the continuous application of molecular biology,rhizobial characteristics will be further revealed.This paper summarizes three aspects of rhizobial genetic diversity,namely,the composition,the research status and the research method progress,for the purpose of providing some ideas for bacteria classification workers.更多还原
