More Information
  • Bacillus spp. is widely used as a biological agent in the management of crop diseases. B. velezensis is a novel species of the genus Bacillus that produces various secondary metabolites, shows a broad spectrum of antimicrobial activities, and promotes plant growth. In addition, it is widely used for the biocontrol of plant diseases. Here, we review the discovery, classification, antimicrobial substances and related gene clusters, effect on microbiota, quorum sensing system, antagonistic mechanism, and application of B. velezensis. This review summarizes the current knowledge, highlights existing problems regarding applications of B. velezensis for plant protection, and discusses future directions for research on this bacterial species. We hope our review will provide a useful reference for studies on B. velezensis and speed up the development of new formulations for its practical applications.

Abstract: Bacillus spp. is widely used as a biological agent in the management of crop diseases. B. velezensis is a novel species of the genus Bacillus that produces various secondary metabolites, shows a broad spectrum of antimicrobial activities, and promotes plant growth. In addition, it is widely used for the biocontrol of plant diseases. Here, we review the discovery, classification, antimicrobial substances and related gene clusters, effect on microbiota, quorum sensing system, antagonistic mechanism, and application of B. velezensis. This review summarizes the current knowledge, highlights existing problems regarding applications of B. velezensis for plant protection, and discusses future directions for research on this bacterial species. We hope our review will provide a useful reference for studies on B. velezensis and speed up the development of new formulations for its practical applications.
