摘要：Fusarium oxysporum is a common soil-borne pathogen that causes serious economic losses in tomato crops worldwide. The purpose of this study was to evaluate the influence of the bio-control agents Bacillus amyloliquefaciens SN16-1 and Pseudomonas fluorescens SN15-2 and the pathogen Fusarium oxysporum f.sp. lycopersici (FOL) inoculation on tomato rhizosphere bacterial communities and growth, as measured by terminal restriction fragment length polymorphism (T-RFLP). Treatment with SN16-1 and SN15-2 had a transient influence on indigenous bacterial communities, withSN16-1 showing great potential for controlling FOL. The corresponding genera of terminal restriction fragments (T-RFs) that were significantly altered after 10days were obtained using Ribosomal Database Project (RDP) database comparison. Genera that produce antibiotics and promote plant growth were activated by SN16-1 and FOL treatments, indicating that SN16-1 responds quickly to FOL invasion. Moreover, the bioremediation activity characteristic of certain genera and the levels of enzymes that degrade pathogen cell walls were decreased while bacterial nutrient cycling and plant growth promotion were enhanced with FOL treatment. In conclusion, we found that SN16-1 possesses the capacity to control tomato wilt, acts synergistically with soil microbes and does not have a persistent effect on the rhizosphere bacterial communities of tomato.
