Abstract: Myxobacteria, which are important micropredators, possess multiple mechanisms and important application potentials in biological control of plant diseases. However, only few studies in this field have been reported, and there is no related research was performed or published in China. In order to arouse the research attention of researchers in biocontrol function of myxobacteria, this paper reviewed the biocontrol mechanisms of myxobacteria, and the research progress of myxobacteria in biological control of plant diseases. In addition, some current limitations and future directions about the research of biocontrol function of myxobacteria were also discussed, which was expected to provide reference for myxobacteria application in plant disease control.

Key words: myxobacteria, biological control, plant disease

摘要： 粘细菌是重要的微生物捕食者，具有多重生防机制，在植物病害生物防治方面具有重要的应用潜力。然而，目前对粘细菌生物 防治作用效果及机制的研究不多，国内尚无相关报道。为引起国内研究者对粘细菌生物防治作用研究的重视，分析了粘细菌的 生物防治机制，综述了粘细菌在防治植物病害方面的研究进展，并讨论了目前粘细菌生物防治作用研究中的一些瓶颈以及未来 的发展方向，以期为粘细菌在植物病害防治中的应用提供参考。
