Antifungal Activity and Mechanisms of 2-Nonanone, a Volatile Organic Compound Produced by Bacillus velezensis TCS001, against Botrytis cinerea

Key Points

• The study aims to investigate the antifungal properties of 2-nonanone produced by Bacillus velezensis TCS001 against Botrytis cinerea.
• Used knockout mutants to assess growth and pathogenicity changes in Botrytis cinerea,
• Measured sensitivity of these mutants to 2-nonanone.
• Knockout mutants showed impaired growth and abolished pathogenicity,
• Sensitivity to 2-nonanone was significantly reduced, confirming it as a key functional target.
