FPB - 2021 - Azri et al - Physiological and proteomic analyses of Tunisian local grapevine cultivar Razegui in response to drought stress.


ABSTRACT: Cuttings from Razegui cultivar were cultivated in sand for 2 months according to the method we have described previously (Azri et al. 2020). Then grapevine plantlets were further grown in pots containing sand/peat mixture (2/1, v/v), in a controlled greenhouse (16 h light/8 h dark at PAR 300 μmol m-2 s-1 photoperiod, 24 °C day/20 °C night temperature and 65-75% relative humidity). They were watered daily with tap water and supplemented once a week with 100 mL of Gibeaut’s nutrient solution (Gibeaut et al. 1997). Drought stress was applied according to our previously described procedure (Azri et al. 2020): plants with 10-15 leaves were either irrigated daily with water (control) or non-irrigated at all (water deficit). After 4 time points (day 0, 4, 8 and 16) of water deficit, the 4th fully-developed leaf was harvested and used for physiological analyses. Three independent biological experiments were performed consisting each in 2 treatments (control and water deficit) and 3 plants per time point and treatment. Proteomic analysis was performed on the 5th fully developed leaves at the time point 16 days of drought treatment. Irrigated and non-irrigated leaves were harvested immediately in liquid nitrogen and stored at - 80 °C until analysis. Three biological replicates were carried out for each treatment.
