根瘤菌多样性和系统发育研究的多相分类体系及其进展

Progress of Polyphasie Taxonomy of Rhizobial Diversity and Phylogeny

摘要:

近年来对新的根瘤菌资源的不断发掘及现代分子生物学技术的发展和应用使根瘤菌分类研究有了突破性进展。多相分类通过综合获取信息，多种方法相互印证、互为补充，推进了根瘤菌的表型、遗传型和系统发育三方面的发展，从而较全面地反映根瘤菌的生物多样性特征，是根瘤菌多样性研究工作中常常采用的技术手段。文中主要阐述了根瘤菌多相分类体系中的主要方法及现代根瘤菌系统发育地位的研究和进展。

Abstract:

In recent years it has made great development on the taxonomy and phylogeny with the discovery of new rhizobia resource and application of molecular methods. Polyphasie taxonomy have driven each of the three (the morphological, the physiological, and the phylogeny) epochs of rhizobia taxonomy and to show the diversity of rhizobia overall. Polyphasie taxonomy have been seemed as the most frequently used technique and methods. This paper presents a review of the main methods of the polyphasie taxonomy system and the phylogeny of rhizobia.
