Three major research lines – A, B and C below (C is the present work):

A. Study of aflatoxin-producing Aspergillus spp.: role of peroxidation and ageing in the induction of Aflatoxin biosynthesis. This study has provided the basis for improved strategies of conservation of cereals and oily seeds.

B. Study of molecular signals inducing defense responses in plants: role of oxidative processes in the transduction of signal molecules acting as elicitors of plant defense responses.

C. Study of the mechanisms of action of yeasts acting as biocontrol agents of postharvest fungal pathogens of horticultural and fruit crops, the optimization of the activity of these agents, the prevention, monitoring and detoxification of the mycotoxinsOchratoxin A in wine-grapes and wine, and Patulin in pome fruits and pome fruit-based juices, also through the identification and use of yeast gene(s) involved in the detoxification process.

This research activity has important applicative implications: it contributes to addressing the goals indicated by EU legislation (2009/128/CE), which aims at strongly reducing the utilization of chemicals in agriculture; it represents an important contribution to Food Safety, since EU (as well as other countries in the world, including US) have set the highest tolerable levels of mycotoxins in food and feed (EC Regulation 1881/2006); it contributes to Food Security, since it paves the way to the utilization and commercialization of food that should otherwise be discarded.
