根瘤菌分类研究进展及存在的争议

Taxonomy of Rhizobia: Progress and Disputation

摘要:

根瘤菌是一类与农业生产关系密切的细菌。近年来, 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, 新的根瘤菌资源的不断发掘, 根瘤菌的分类体系也不断地被完善。文中主要阐述了根瘤菌分类系统的演化历史、目前存在争议及相关的研究进展。

Abstract:

Rhizobia, which are symbiotes of leguminous plants, are of considerable environmental and agricultural importance due to their nitrogen fixation properties. With the development of new molecular biological techniques, new methods are applied to the rhizobia classification, with the polyphasic approach being the most reliable. This advancement has led to the reorganization of already classified species of rhizobia, as well as to the identification of new species from an array of as yet unexplored legume plants from various environments. Here we discuss the progress made in the evolutionary systematics of Rhizobia, as well as the disputes associated therewith.
