Vitis vinifera cultivar:Sangiovese Transcriptome or Gene expression

The analysis of the grape transcriptome (RNA-sequencing) was performed to evaluate the impact of 4 water deficit on the berry metabolism. Four irrigation treatments were imposed on Sangiovese grapevines: control vines were irrigated based on actual water consumption of vines and adjusted in order to maintain the stem water potential above -0.5 MPa (1); severe or moderate regulated deficit irrigation regimes were applied from berry pea-size until the beginning of veraison (2) or from the beginning of veraison until the harvest (3), and a severe regulated deficit irrigation was imposed during the lag phase (4). Fruit samples were harvested and analysed at 3 developmental stages: beginning of veraison, mid-ripening, harvest.
