ETAP: Efficiency of transpiration and adaptation of plants to dry climates

Team presentation


The ETAP team (Efficiency of Transpiration and Adaptation of Plants to dry climates) aims to identify genetic and agronomic targets to improve water use efficiency in grapevine systems exposed to abiotic stresses.

Genetic variability for tolerance to drought, heat and low nitrogen is analysed at the leaf level through the development of simulation models for transpiration, photosynthesis and plant water status. At the whole-plant level, we develop tools to provide a 3D reconstruction of grapevine for contrasting genotypes and training systems, so as to simulate shoot microclimate and canopy gas exchange through the integration of leaf-based models. We also analyse how heat, nitrogen status and carbon availability affect yield components.

We collaborate with local (UMRs AGAP, BPMP, SPO, SYSTEM et INNOVATION), national (UMR EGFV Bordeaux) and international (University of the Balearic Islands [Spain], University of Lisbon [Portugal], Geisenheim University [Germany], INTA [Argentina]) partners in various projects ranging from the genetics of tolerance traits to the optimisation of training systems.
