Massimo
Nepi
Professore Associato

Presentation

Graduated in Biology at the University of Siena in 1991; PhD awarded in Agricultural Biology at the University of Pisa in 1995. From January 2001 to October 2016 I was a researcher at the University of Siena and since November 2016 I am Associate Professor in Botany. My research is focused mainly on the reproductive biology of higher plants and particularly the relationships between plants and animals during pollination. Most of these relationships are based on mutualism, since animals are "rewarded" with pollen and nectar while they perform pollination. My studies aim to discover how diversity of rewards may affect the relationships with pollinators in the present days and during evolution.

Research

"Partner manipulation in plant-insect relationships" (project funded by PRIN 2017. University of Florence (PI), University of Milan, University of Trento, University of Parma, University of Siena)

Animals, throughout their evolution, have been exposed to a diversity of plant-derived chemicals affecting their physiology and behaviour. The mechanisms by which neuro-active components of these products exert their effects have been widely described, but the question of why they have these effects has been almost totally ignored. With the present project we aim to understand why some plant-derived chemicals affect animal behaviour, by testing the hypothesis that neuroactive compounds produced by plants evolved not (or not only) as a mere deterrent for animals, but also as a plant tool to attract and manipulate animal behaviour. If supported, the hypothesis would place plant-animal interaction in a different ecological context opening new ecological and neurobiological perspectives. Ant-plant relationships, offer the ideal study model to test such a hypothesis. Particularly relevant are ant mutualistic symbiosis with plants producing extra-floral nectar (EFN). Those plants attract ants via EFN, which in turn, protect the plant against potential enemies. In this model system, a combined approach involving plant chemistry and physiology, ethology and neurobiology, transcriptomic and microbial ecology will be essential to investigate the problem.
