Activités de Recherche

My research activity aims at characterizing legume nitrogen nutritional strategies and their variations in response to modification of environmental or internal factors (such as CO2, solar radiation, nitrate, root pruning …). For this, I develop an ecophysiological approach that describes the establishment of roots and nodules together with their N uptake activities for nitrate uptake and symbiotic N2 fixation. The analysis accounts for interactions between nitrogen nutrition and carbon nutrition, and includes explicit representation of root architecture. Plant-microbe interactions in the rhizosphere can also be considered, in collaboration with microbial ecologists of the EcolDur group.

Setting up those analyses at different scales allows :

 - developing ecophysiological frameworks or models at the plant scale as tools to better characterize genetic variability associated to N nutrition in legumes, either based on intra-specific genetic variation (natural or induced, in pea) or on interspecific genetic variation (e.g. on 10 legumes species), in collaboration with geneticists of the GEAPSI group.

- quantifying nitrogen fluxes generated by legumes in the field during the growth cycle of legume crop (symbiotic fixation symbiotique, nitrate absorption), and the following crop in rotation (through legume crop residues and pre-crop effects), and their consequences on nitrogen fluxes in the soil-plant-atmosphere continuum (N2O emissions, mineralization and lixiviation of nitrate), in collaboration with agronomists of the EcolDur group. The comparative analysis of a wide range of legume species will allow identifying the plant traits determining those fluxe and in fine translating them into services et dis-services.
