Research interests

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).
