Verticillium dahliae is a broad host-range phytopathogenic fungus that causes destructive vascular wilt on plants worldwide. Cytochrome P450 monooxygenases, also known as CYPs/P450s, are broadly distributed in organisms and are involved in a diverse array of molecular/metabolic processes. In this study, using reverse transcription quantitative PCR analysis, we observed that the expression of a P450 gene (Chr2g00380) in the E-class P450, group IV from V. dahliae isolate JR2 was highly induced during tomato infection. Targeted deletion of Chr2g00380 in JR2 did not affect hyphal growth and morphology, however, the mutants exhibited increased sensitivity to H2O2 and defects in melanized microsclerotia formation compared with the wild type. Loss of Chr2g00380 resulted in reduced virulence on tomato and tobacco plants but did not cause phenotypic changes in infection structure formation or in the penetration of cellophane membranes. These data provide evidence for an involvement of a cytochrome P450 monooxygenase in virulence in V. dahliae.
