Inhibitory Effects and Mechanisms of Volatile Organic Compounds from Schizophyllum commune Against the Pepper Gummosis Pathogen Fusarium tricinctum

BACKGROUND: . METHODS: . Compounds were identified using headspace solid-phase microextraction gas chromatography-mass spectrometry, and the antifungal mechanism of this component was explored. RESULTS: . Mechanistically, 1-octen-3-ol disrupted cell membrane integrity by increasing alkaline phosphatase and β-1,3-glucanase activities, leading to enhanced permeability and content leakage. It also induced oxidative stress by promoting reactive oxygen species accumulation via elevated NADPH oxidase and superoxide dismutase activities, while suppressing antioxidant enzymes. CONCLUSIONS: through membrane disruption and oxidative stress, offering a promising eco-friendly strategy for controlling gumming disease.
