CARATTERIZZAZIONE DEL PROFILO DI ESPRESSIONEDI GENI COINVOLTI NEL METABOLISMO DI PARETEDURANTE LA MATURAZIONE E L'APPASSIMENTODELLA BACCA DI Vitis vinifera cv Corvina

During ripening of grape (Vitis vinifera cv Corvina ) berries softening occurs concomitantly with the second growth phase of the fruit and involves significant changes in the properties of cell wall polysaccharides. Expression profiles of genes involved in cell wall metabolism and water transport were examined by microarray analysis during six berry developmental stages, starting from veraison. Genes belonging to gene families involved in cell wall metabolism, that showed significant modulation (FC ≥2) were analysed by Real time RT PCR analysis.
