Relevance of the transcription factor PdSte12 in Penicillium digitatum conidiation and virulence during citrus fruit infection.

Abstract excerpt

Green mould, resulting from Penicillium digitatum, is the most important postharvest disease of citrus. In a previous study, the PdSte12 transcription factor gene was identified, and disruption mutants were obtained. In the present study, the ΔPdSte12 mutants generated through gene replacement showed significantly reduced virulence during citrus fruit infection. Virulence was affected not only in mature fruit but...
