摘要： Background and aimsThe diversity and stability of belowground microbiota communities influence plant health. However, changes over time in the microbiome composition associated with healthy and diseased trees remains poorly understood. The goal of this study is to understand the changes in belowground microbial community associated with Verticillium wilt of smoke trees to provide a basis for the combination of biological agents and chemical measures to combat Verticillium wilt of smoke trees.MethodsIn this study, we used an amplicon-based approach to reveal distinct differences in the diversity, structure and composition of the belowground microbial communities of healthy and diseased smoke trees from June to October.ResultsThe structure, composition and interactions of the belowground microbial communities are different between healthy and diseased smoke trees from June to October. The co-occurrence networks of the belowground microbial community changed with the severity of the disease over time. Additionally, the structural community of healthy and diseased trees showed a shift in keystone OTUs.ConclusionsThis study improves our understanding of the belowground microbial community composition associated with smoke trees in healthy and diseased conditions, offering the potential to both manipulate the plant microbiome to promote plant health and to provide an integrated management strategy of smoke tree.
