I am a plant geneticist from the University of Toulouse in France. With my colleagues in the ECOLAB laboratory, I am studying plant adaptation to environmental stresses (either biotic or abiotic) using the wild legume Medicago truncatula as a model.
By making use of the wide biodiversity existing within this plant species and based on whole genome re-sequencing data of natural accessions, we aim at identifying key genetic factors (genes and small non-coding RNAs) involved in adaptive process to changing environment.
By combining genetic and large-scale genomic approaches with population genomics, we intend to understand population structure and history as well as the contribution of micro-evolution in adaptation to environmental stresses.
Major Current Research Topics
'Genetic and molecular analyses of the natural biodiversity in legumes to identify adaptation mechanisms to environmental stresses'
- Biotic stresses: Root diseases caused by the soil-borne pathogens Ralstonia solanacearum & Verticillium sp.,
- Abiotic stresses: heavy metals (cadmium), salinity, drought
- Micro-evolution & Plasticity
‘Study of the adaptive contribution of small RNAs to legume root biotic interactions'
‘Biogeography analysis using patterns of genetic variation within modern plant accessions to reveal ancestral genome admixture and to infer population adaptation in the wild legume species Medicago truncatula'
