Microbial community succession in steam-sterilized greenhouses infected with Fusarium oxysporum.

ABSTRACT: Fusarium is an economically important crop pathogen but spends a large part of its life cycle in bulk soil environments where it interacts with a diverse community of soil microbes. Antagonistic interactions (e.g. competition) between the resident microbial community and Fusarium could constrain the growth of Fusarium in soil, which might therefore slow or prevent Fusarium establishment. We tracked Fusarium oxysporum in floriculture greenhouses where the soil had been steam-sterilized to remove Fusarium. The data indicated a resurgence of soil bacteria and fungi during the first 90 days post-sterilization, followed by a rapid decline in subsequent weeks, which was associated with an increase in F. oxysporum abundance at 148 days post sterilization. These changes over time were associated w
