The main focus of my research work is to study the respiratory metabolism of plants using stable carbon isotopes. The aim is to determine the isotopic discrimination during respiration to understand the metabolic origin of the C released by the respiration of plants subjected to different environmental conditions (temperature, drought, N nutrition, etc.). Therefore, we measure the natural abundance in 13C/12C in the CO2 evolved during respiration of leaves and roots of different species (C3 and C4) as well as in the putative respiratory substrates (mainly soluble sugars and organic acids). These measurements are also carried out using (i) the 13C-labeled CO2 to label the photoassimilates and then to follow the labeled C in respired CO2 and in metabolites, and (ii) the positionnally labeled metabolites for example glucose or pyruvate labelled in C atom position C-1, C-2 or C-3, etc. We have already demonstrated that, contrary to what was assumed until recently, CO2-respired by leaves is enriched in 13C, while that released by roots is depleted in 13C, compared with the metabolites in corresponding organs. This is validated in both C3 and C4 herbs and we demonstrated the metabolic origin of this opposite isotopic discrimination between leaf and roots.

Currently, I study the impact of the inorganic nitrogen source (NO3-versus NH4 +) on the metabolism of sugars and organic acids and respiratory metabolism, and thus on the 13C/12C composition of respired CO2 and respiratory substrates. Since NO3-is mainly assimilated in the leaves, while NH4 + is preferentially assimilated in the roots, their assimilation would affect the anaplerotic activity of the enzyme PEPc (which enriches in 13C the C fixed), it is expected that the metabolites and the CO2 respired by these organs will be differently impacted under nitrogen nutrition with various NO3-: NH4 + ratios in supplied N (a PhD thesis in progress).

Stable isotopes: Use of stable isotopes in ecophysiology (basic concepts on stable isotopes and isotope effects, isotopic discrimination during photosynthesis in C3, C4 and CAM plants and during respiration, isotope labelling, use at ecosystem level) (Lecture : License 3 and Master 2).

Drought resistance: Mechanisms of resistance/adaptation of plants to drought (morphological, structural and physiological adaptations) (Lecture: Master 1).

Soil: Physicochemical and biological properties of soil, degradation of organic matter in soil, mineralizations and humification, different types of humus and different types of soil (Lecture: License 3).

Water Relations: Leaf water potential and its components (measurement with pressure chamber), calculation of osmotic adjustment (Practical course: License 3).

Soil water: Measurements of soil properties related to water retention (total porosity, apparent density, field capacity, permanent wilt point, water reserve useful for plants) (Practical course: License 3).

Leaf gas exchanges: Measurement methods and calculations of different parameters (photosynthesis, transpiration, stomatal conductance, internal CO2 concentration, water use efficiency), limitations of the methods (problems related to heterogeneity of stomatal closure, mesophyll resistance, CO2 concentration in chloroplasts, cuticle resistance to water vapour diffusion (Course: License 3).
