Genomics and metabolomics assisted functional characterization of <i>Bacillus velezensis</i> D83 as a biocontrol and plant growth-promoting bacterium.

ABSTRACT: Diseases triggered by phytopathogenic bacteria lead to substantial economic losses within the realm of agricultural production. Bacillus velezensis is an important agricultural biocontrol and plant growth-promoting bacterium. In this study, we evaluated the inhibitory ability of B. velezensis D83 against eight plant pathogenic fungi. D83 has a broad spectrum of antagonistic activity against these eight plant pathogens. In addition, our study found that D83 promotes seed germination and plant growth in maize and tobacco, and this growth-promoting ability is related to its growth-promoting properties such as indoleacetic acid production, nitrogen fixation, and phosphate solubilization. This effect of promoting plant growth is more effective than the microbial preparations on th
