Construction of Engineered Bacillus velezensis XY40-1 and the role of degQ in Enhancing Fengycin Synthesis and Pepper Disease Resistance

Key Points

• This research aims to understand how degQ influences fengycin production and disease resistance in Bacillus velezensis XY40-1.
• Construction of Bacillus velezensis strain XY40-1
• Assessment of fengycin synthesis levels
• Evaluation of biofilm formation capabilities
• Analysis of biocontrol activity against pathogens
• DegQ significantly enhances fengycin synthesis in XY40-1
• Improved biofilm formation was observed in the presence of degQ
• Increased biocontrol activity against diseases was reported for XY40-1 with active degQ
