Curriculum Vitae

The research activity is mainly focused on:
Genotype-environment interactions. The whole genome sequencing of three ‘Nebbiolo’ clones is the starting point for the study of the interactions between genotype and climatic conditions of cultivation, that define the wine terroir. The research is carried out using agronomic, transcriptomics (RNA-seq) and epigenomics (BS-seq) approaches, in order to link gene expression profiles between three clones and four different cultural environments. In parallel, the interaction between genotype and environment is also studied in vitro on ‘Sangiovese’ and ‘Cabernet Sauvignon’, in order to characterize the plasticity of somatic embryogenesis and study the molecular mechanisms underlying this process (the study of WOX genes in Arabidopsis plants genetically transformed).
Plant-pathogen interactions. The study of plant responses to biotic and abiotic stresses is conducted through eco-physiological, transcriptomics (microarray, RNA-seq e qRT-PCR), small RNAs (miRNAs and vsiRNA) and epigenomics analysis, with particular attention to major grape viruses (GRSPaV and GFkV) and phytoplasmas (Flavescence dorée) and/or under water stress conditions.
Plant-AM fungi interactions. The study of the interaction and responses of mycorrhizal and non-mycorrhizal tomato and grape plants to biotic (e.g. insects) and abiotic (e.g. water stress) is performed through eco-physiological, metagenomics and transcriptomic analysis.
