Objectif The present project aims at providing a fundamental basis for assessing adaptation features of woody plants in the context of climate change. It takes into account the main physiological processes and morphological-structural alterations involved in the global plant responses to combined effects of (i) elevated CO2, (ii) drought constraints and (iii) high light and temperature stresses which have been shown to strongly interfere with drought stresses.In the next decades, European trees and woody communities will have to face more severe drought conditions and will be exposed to increasingly atmospheric CO2 concentration. Since atmospheric CO2 may strongly interfere with drought adaptation features of plants, a crucial question, that largely remains unaddressed, is whether elevated CO2 could modulate the drought susceptibility of plants, so that the current physiological and ecophysiological work made to characterize the drought resistance of woody species could be inadequate.The specific objectives of the project are :(1) to analyze plant performances in different environment simulating climate change with respect to three main determinants: - Water-use efficiency (WUE), ie the ratio of carbon assimilation to transpiration (or of biomass production to transpirational water losses) - drought tolerance mechanisms : (i) stress tolerance of photosynthetic processes; (ii) protection against oxidative stresses; (iii) xylem hydraulic efficiency and safety; (iv) root growth and interactions with soil water; (v) osmoregulation - whole tree functional integration with emphasis on the role of hydraulic and metabolic root-shoot signalling in controlling leaf processes.(2) to assess the role of ectomycorrhizal associations as a plant component responding to climate change and in turn affecting plant water relations, plant nutrient status, and thus plant performance, in the context of climate change.Plant models will be European forest and fruit species (Pinus pinaster, Quercus species, Prunus avium) of ecological and economic interest both in northern and mediterranean areas.
