Abstract: Bacillus spp. is widely used as a biocontrol microbe against plant diseases in the world, and it is one of the research hotspots in microbial ecology. Many Bacillus strains had been finished the whole genomic sequencing at domestic and abroad in recent years. The paper reviewed the biological control mechanisms of Bacillus from three aspects:the interaction between secondary metabolism and antagonistic effect, biofilms and competitive effect, the relationship of plant-Bacillus-pathogen and induced disease resistance (ISR). The plant diseases resistance can be improved by molecular modification of Bacillus functional expansion. This article also discusses the application of Bacillus bio-control agents on commercialized production, and its utilization on agriculture areas. In recent years, Chinese scholars have yielded much in the Bacillus research field, it lays the foundations for further realization of industrialization and application of Bacillus.

Key words: Bacillus, biocontrol, plant disease, plant-microbe interaction
