摘要： Aims Banana Fusarium wilt (Fusarium oxysporum f. sp. cubense tropical race 4) is a typical destructive soil-borne disease, which was the main limiting factor for the sustainable development of the banana industry worldwide. In banana production, soil physiochemical properties and soil microbiome were effectively affected the occurrence and spread of Fusarium wilt. However, there is still a lack of systematic research, particularly in exploring the correlation between the occurrence of banana Fusarium wilt and soil properties across various climates and soil types. Methods In this study we investigated the soil physicochemical properties, bacterial and fungal community composition, and pathogenic fungal abundance in 140 banana plantations which were affected by banana Fusarium wilt in Yunnan Province, China. Results The results showed that the abundance of soil-borne pathogenic fungi was positively correlated with total phosphorus, total nitrogen, organic matter, urease activity, annual precipitation, and the alpha diversity of bacterial and fungal communities. In contrast, it showed a significant negative correlation with the annual mean temperature. As the abundance of pathogen increased, numerous potential disease-suppressive bacterial genera (such as Rhodanobacter, Gemmatimonas, Novosphingobium) and soil-borne pathogenic fungal genera (such as Plectosphaerella, Nigrospora, Cyphellophora) also increased, and the co-occurrence network showed a higher modularization index. Conclusions The results enhance the understanding of the patterns of soil-borne pathogenic fungal population dynamics in banana plantations, which would provide evidence and guidance for reducing pathogenic fungal abundance and selecting beneficial microorganisms in banana production. Furthermore, this would provide a theoretical basis for sustainable prevention and control of banana wilt disease.
