A comprehensive understanding of the biocontrol potential of Bacillus velezensis LM2303 against Fusarium head blight.

ABSTRACT: Fusarium head blight (FHB) mainly caused by F. graminearum, always brings serious damage to wheat production worldwide. In this study, we found that strain LM2303 had strong antagonist activity against F. graminearum and significantly reduced disease severity of FHB with the control efficiency of 72.3% under field conditions. To gain a comprehensive understanding of the biocontrol potential of strain LM2303 against FHB, an integrated approach of genome mining and chemical analysis was employed. The whole genome of strain LM2303 was obtained and analyzed, showing the largest number of genes/gene clusters associated with biocontrol functions as compared with the known biocontrol strains (FZB42, M75, CAU B946). And strain LM2303 was accurately determined as a member of the B. velezensis clade
