is one of the most cosmopolitan and diverse bacterial group nodulating a variety of host legumes in Africa, however, the diversity and distribution of bradyrhizobial symbionts nodulating indigenous African legumes are not well understood, though needed for increased food legume production. In this review, we have shown that many African food legumes are nodulated by bradyrhizobia, with greater diversity in Southern Africa compared to other parts of Africa. From a few studies done in Africa, the known bradyrhizobia (i.e., ) along with many novel species are the most dominant in African soils. This could be attributed to the unique edapho-climatic conditions of the contrasting environments in the continent. More studies are needed to identify the many novel bradyrhizobia resident in African soils in order to better understand the biogeography of bradyrhizobia and their potential for inoculant production.
是在非洲使各种豆科宿主植物结瘤的最具世界性和多样性的细菌群体之一。然而，尽管增加食用豆类产量需要了解根瘤菌共生体在非洲本土豆类植物上结瘤的多样性和分布情况，但目前对此了解并不充分。在本综述中，我们表明许多非洲食用豆类植物都被根瘤菌结瘤，与非洲其他地区相比，南部非洲的根瘤菌多样性更高。从在非洲进行的一些研究来看，已知的根瘤菌（即 ）以及许多新物种在非洲土壤中最为常见。这可能归因于该大陆不同环境独特的土壤气候条件。为了更好地了解根瘤菌的生物地理学及其生产接种剂的潜力，需要开展更多研究来鉴定非洲土壤中存在的众多新型根瘤菌。
