In order to find out the microorganisms that can improve the environmental adaptability of soybeans, the rhizosphere microbial diversity of wild and cultivated soybeans was studied using the Illumina MiSeq sequencing method. There were no significant difference in the dominant fungal phyla and dominant fungal genera of wild soybean rhizosphere and cultivated soybean rhizosphere. However, there was a significant difference in arbuscular mycorrhizal fungi (AMF) between wild soybean rhizosphere and cultivated soybean rhizosphere. Under controlled conditions, the relative abundance ratio of Paraglomus in wild soybean rhizosphere was much larger than that in cultivated soybean rhizosphere. While, the relative abundance of Funineliformis and Rhizophagus in cultivated soybean rhizosphere were much higher than that in wild soybean rhizosphere. Interestingly, in fields, no AMF was found in cultivated soybeans rhizosphere, and only Paraglomus with drought resistance was found in wild soybeans rhizosphere. It was concluded that under different growth conditions, there were differences in the number and types of rhizosphere fungi between wild soybean and cultivated soybean, and the similarity of fungal community structure was also different.
