Verticillium wilt is a devastating soil-borne disease that significantly impacts cotton production, necessitating the development effective biofumigants for its control. In this study, inhibitory effect of total volatile organic compounds (VOCs) produced by Talaromyces purpureogenus CEF642N against dahliae were evaluated using one strain many (OSMAC) strategy and analyzed through metabolome. was found to produce two primary VOCs, 3-octanol 2-octenal, (E)-, both which demonstrated significant antifungal activity. Transcriptome analysis mycelium grown on various solid media revealed notable differences in expression genes associated with arachidonic acid metabolism, lipoxygenase (LOX), lytic enzymes. These findings provide foundation future research aimed at identifying key involved eight-carbon biosynthetic pathway.
