Ricerca

Physiological and molecular interactions among plants and environmental constrains

In this research area, I tried to disclose some of the biological and molecular mechanisms involved in woody plant’s reaction to abiotic stresses, moving from cell/tissue to whole crop level. At cell/tissue level I studied the molecular and biochemical change involved in the reaction to salinity and drought, mineral nutrient stress (Cu, Zn, Ni), pollution effects (heavy metals, ozone stress) and also emerging xenobiotic contaminants (caffeine, erythromycin, SDS, diclofenac, etc.). In these studies, I selected woody plant having an immediate interest for agricultural production such as olive, peach, and poplar but also horticulture crops such as tomato. In particular, I work on olive tree as a crop model for the Mediterranean environmental constraints (salinity, drought) from plant to orchard level. The basic idea was to understand how these crops for fruit (olive, peach, tomato) and wood (poplar) production resist to abiotic stresses and how we can improve by crop management or genetic improvement strategies their resistance traits.

 

Fruit composition and antioxidant compounds

In the last years I studied apple aimed to prove their health promoting effects. Pharmacological properties of fruit are linked to the abundance of phytochemical constituents (i.e. polyphenolic compounds) having antioxidant activity able to scavenge free radicals, physiologically important and that are involved in numerous pathologies. Results highlighted that apple fruit is a very important source of flavonoids, in particular of procyanidins, catechin, epicatechin, chlorogenic acid and quercetin conjugated compounds. These compounds have been largely studied in order to maximize these compounds in apple fruits or derived products.

 

Atmospheric pollution. At the start of my carrier, I focused my research activity on the study of an important environmental concern for plant growth and productivity: the ozone (O3) pollution. The global atmospheric ozone concentrations have risen by about 36% since the pre-industrial times, together with a nearly 30% increase in CO2 concentrations over the same period. Ozone is one of the most powerful oxidants and plant cells respond quickly to O3 stress by induced ROS production. By using tomato, trifolium and melissa as herbaceous plant models and poplar (Populus spp.) and liriodendron as woody plant models, I tested the effect of acute and chronic O3 exposures on the physiological, biochemical, and molecular plant defense and adaptation mechanisms. My studies were focused on plant signal transduction in response to O3 stress and on the interactions of these signal with other metabolites and defense mechanisms.

 

Woody plant germplasm conservation. This research line starts from the consideration that plant biodiversity recovery, conservation and valorization strategies are crucial processes for the preservation of ancient crop varieties in small and marginal agricultural areas. A detailed knowledge of plant genetic variability is crucial to correctly preserve the germplasm and eventually use it for future genetic improvement program. The many systems studied in this research area are located in hilly and mountainous regions in Tuscany (Casentino, Comune di Zeri, Capannori, Elba) that are characterized by a fast population decline and loss of several agricultural activities due to strong international competition, farmer ageing and more attractive economic activities (industry, commerce, and tourism) in the surrounding areas.

 

Development of Innovative Systems for Environmental Education. This research line has been developed in the last years under the project ACARISS (Accrescere le Conoscenze sull’Ambiente e i Rischi connessi all’Inquinamento Coinvolgendo le Scuole con la Sperimentazione - Projects Funded by PAS FAS-Tuscany) actions. Then continued with FIlo Diretto tra scuole e Università: la ricerCa In clAsse (FIDUCIA) Projects Funded by Ministero dell’Istruzione, dell’Università e della Ricerca Dipartimento per la Formazione Superiore e per la Ricerca Direzione Generale per il Coordinamento, la Promozione e la Valorizzazione della Ricerca (PANN15T3_00469). The aims of these projects are to promote science, starting from education in secondary schools. Using Internet-based communication technologies and Inquiry Based Learning methods, the project allowed to connect the schools with the research laboratories and developed functional approaches useful for easy science learning.
