My thesis is entitled «A global approach to predicting interactions between soils, plants and climate using metabolomic analysis: the case of the thyme ecosystem». This work is based on a multidisciplinary approach combining analytical chemistry, chemometrics and ecology. The aim of my thesis is to study the adaptation of thyme to environmental constraints in the current context of climate change. A non-targeted metabolomic analysis is used to identify molecular markers associated with different environmental stresses. The analyses will focus on thyme populations distributed along a climatic gradient. The pedoclimatic conditions of the study sites and their historical climatic data are also taken into account. These data will be the subject of a multi-block chemometric analysis aimed at linking changes in thyme metabolism to changes in climatic conditions.
