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.

Abstract

knockout mutants showed impaired growth, abolished pathogenicity, and reduced sensitivity to 2-nonanone, confirming it as a key functional target. These findings highlight TCS001 as a promising biocontrol agent against gray mold.
