Responses of soil microbial communities to the invasion of exogenous fungi

Fusarium oxysporum is known as a biological pollutant in the farmland soil, that causes vascular wilt on a wide range of cash crops, which is the most destructive disease of plant worldwide. F. oxysporum is a fungus that can colonize and grow saprophytically in plant debris and increase pathogen viability in soil. It is almost impossible to remove once successful colonization. How to effectively reduce the pathogen population and restore the beneficial microbial community in soil is an important subject to control the Fusarium wilt. The main objective of this study is to explore influences of F. oxysporum invasion on the microbial community and to screen efficient biocontrol agents from microorganisms with changing relative abundance.
