Characterization of Pea (Pisum Sativum L.) genes implicated in arbuscular mycorrhiza formation and function
2010
The arbuscular mycorrhizal (AM) association results from a successful interaction between the genomes of the two symbiotic partners. In this context, the aim of my research was to better characterize the role of the late stage symbiosis-related pea genes PsSym36, PsSym33 and PsSym40 in the functional AM (i) by investigating the effect of mutations in the three genes on fungal and plant gene responses and (ii) by creating conditions for the localization of two of the genes, PsSym36 and PsSym40, on the pea genetic map for future map-based cloning. The expression of a subset of ten fungal and eight plant genes,previously reported to be activated during mycorrhiza development, was compared in G…

Untargeted metabolomics of rind essential oils allowed to differentiate two closely related clementine varieties
2021
[EN] Chemical characterization of clementine varieties (Citrus clementina Hort. ex Tan.) essential oils (EO) can lead to variety identification and valorization of their potential use in food and aroma industries. The goal of this study was the chemometric discrimination between two very closely related and morphologically identical clementine varieties, Clemenules (NL) and Clemenpons (PO), based on their rind EO, to identify the differential volatile organic compounds (VOCs) and to determine their antioxidant capacity. EO rind volatile profile was determined by gas chromatography coupled to mass spectrometry in Citrus fruit at different ripening stages grown two independent years in two di…
Pianificazione per la conservazione della diversità dei progenitori selvatici delle piante coltivate e delle piante selvatiche raccolte in natura
2022
Le piante selvatiche raccolte in natura (Wild Harvested Plants - WHP) e i progenitori selvatici delle colture (Crop Wild Relatives - CWR), note collettivamente come “Risorse fitogenetiche” (PGR), rivestono molteplici ruoli di rilevanza ecologica, ambientale e socioeconomica perché ad essi si correlano numerosi usi diretti e indiretti, ma anche perché costituiscono un serbatoio di caratteri genetici potenzialmente utili per il miglioramento genetico delle piante coltivate. Ciò rende prioritaria la messa a punto di appropriate strategie di conservazione e valorizzazione. Nella presente tesi vengono presentate le attività che hanno portato alla elaborazione di due inventari delle CWR e delle W…
Effect of Pulp Pigmentation Intensity on Consumer Acceptance of New Blood Mandarins: A Cross-Cultural Study in Spain and Italy
2022
One of the current objectives of different citrus breeding programmes is obtaining new pigmented mandarins. This study investigates to what extent consumer preferences, expectations and purchase intention are affected by the appearance of new mandarins, specifically pulp pigmentation intensity. Four hundred consumers from both Italy and Spain (800 in all) participated in the study. In each country, half were informed about the healthy properties of the anthocyanins responsible for red pulp colouration, while the other half were not. Italians more readily accepted new mandarin varieties than Spaniards, which was linked to them being more familiar with blood oranges. In Italy, both slight- an…
