Genome Sequencing and Characterization of Bacillus velezensis N23 as Biocontrol Agent against Plant Pathogens.

ABSTRACT: The overuse of chemical fungicides against fungal pathogens adversely affects soil and plant health, resulting in environmental problems and food safety. Therefore, biocontrol is considered as an environmentally friendly and cost-effective green technique in environmental protection and agricultural production. We obtained a bacterial strain N23 from a contaminated plate which showed significant inhibition to anthracnose. The strain N23 was identified as Bacillus velezensis based on 16S rRNA gene, gyrA gene, and whole-genome sequence. The bacterium N23 was able to suppress the mycelial growth of numerous plant pathogenic fungi on solid media. Tomato seeds treated with strain N23 showed significantly higher germination levels than untreated ones. Moreover, strain N23 effective
