In a context of water scarcity and global climate changes, the researches at the LEPSE aim at analysing and modelling the responses of plants to drought and high temperatures as well as their genetic variability at the intra- and inter-specific levels.



The main plant responses under study are growth, vegetative and reproductive development, as well as CO2 and H2O gas exchanges. Our hypotheses are tested using large genetic panels (natural accessions, selected lines, mutants, transgenic lines) and environmental conditions (combining growth chambers, greenhouses and field experiments), as well as using biochemical, molecular and biophysical measurements that allow the characterisation of plant organs and tissues. High throughput analyses are performed thanks to the development and use of dedicated phenotyping platforms for which we are pioneers worldwide (the LEPSE is coordinating the French project Investissement d’Avenir PHENOME).

We combine our analyses in models that embark genetic and environmental variability in order to predict the response of genotypes and species to current and future climate scenarios. We mainly use three species: maize, one of the main crop species for human diet, the vine, which is an economically important species in the Mediterranean basin, and the model plant Arabidopsis thaliana, whose vast natural distribution represents a good opportunity to study adaptation to stress. The generic ambition of our research is illustrated by programs running on other species such as wheat, rice, rapeseed…
