Capsidiol, an antifungal sesquiterpene induced in pepper fruit by several fungi is oxidized to the ketone, capsenone, by Botrytis cinerea and Fusarium oxysporum f. vasinfectum Capsenone is less fungitoxic than capsidiol, and its formation may be a detoxification mechanism of importance in overcoming host resistance.
