Phd thesis

My thesis is about hazelnut kernel mould, a postharvest disease that impacts hazelnut edibility. Although several fungal pathogens have been associated with this disease in different countries (such as Aspergillus, Dydimella, Fusarium and Pestalotiopsis), genus Diaporthe, and in particular Diaporthe eres have emerged as the most important pathogen associated it. While the ecology of Diaporthe eres has been recently studied, no data have emerged so far regarding its epidemiology and its interaction with other microorganisms associated with hazelnuts.

The objective of my thesis is to characterize the epidemiology of fungal genera associated with hazelnut kernel mould by mapping the evolution of hazelnut microbiota across different fruit development stages, as well as air samples from the orchard, using a metagenomic approach. In parallel, the isolation and molecular characterization of microorganisms with potential biocontrol activity against Diaporthe and other pathogenic fungi is to be performed. The combination of epidemiological data and microbial resources will hopefully used to design synthetic consortia with biocontrol properties.

Research activities

- Characterization of plant and soil microbial populations through metabarcoding/shotgun metagenomics

- Isolation and molecular characterization of fungal strains of interest
