Research focus


My research aims at assessing the modulation of tomato defense responses caused by beneficial soil fungi. The study involves the use of Solanum lycopersicum plants, arbuscular mycorrhizal fungi and Trichoderma spp. to assess their impact on the performance of aboveground chewing and sucking insect pests as well as their natural enemies (third trophic level). The research deploys a combination of transcriptomic and metabolomics approaches to unravel the molecular and chemical mechanisms underlying microbial induced resistance. In this context, we will work on different lines of tomato plants and our analyses will be complemented with assays on insect performance and behavior which can be directly related to microbe- induced changes in volatile and non- volatile metabolomes.

This project is part of the EU Marie Curie ITN MiRA.
