弗兰克氏菌（Ｆｒａｎｋｉａ）与植物共生结瘤固氮的意义不亚于豆科植物的根瘤菌，并有更广阔的研究开发前景．本文简要介绍了弗兰克氏菌的研究历史；着重评述了弗兰克氏菌的宿主种类、菌种分类、固氮数量、适应范围、固氮特性、新共生体系和侵染作物等的研究进展；并对弗兰克氏菌的进一步研究开发提出思路和展望 The symbiotic relationship between Frankia and plant nodulation and nitrogen fixation is as good as that of leguminous rhizobia and has a broader prospect of research and development. This article briefly introduced the research history of Frankincense. The research progress on host species, species classification, nitrogen fixation, adaptability, nitrogen fixation, new symbionts and infested crops were briefly reviewed. Frankel’s Further research and development of bacteria put forward ideas and outlook
