Welcome to the ECOGEN lab!

The main objective of our team is to understand and predict biotic interactions with plants in the context of global changes by establishing a continuum from molecular biology and quantitative genetics to evolutionary ecology. This lofty goal requests (i) the identification of the main ecological factors acting as selective agents on plants, (ii) the description of the genetic architecture underlying adaptation in plants, and (iii) the identification and understanding of genetic and molecular determinants of adaptation, in particular the ones involved in plant-microbiota-pathobiota interactions and plant-plant interactions.


We work on the wild plant Arabidopsis thaliana as well as on the crop species wheat, rapeseed and tomato. To achieve our scientific goals, we promote interdisciplinarity and we developed strong collaborations at the local, national and international levels. We also offer an environment that favors training in complementary disciplines (ecology, molecular biology and quantitative genetics) and career development in an international spirit.


You like our research! You want to join the team!  Feel free to contact any member of the team to initiate discussion. We may have some money on current projects or we can help you to apply for some fellowships (ERC, Marie-Curie, EMBO…).

Human activities generate numerous global changes, such as climate change, agricultural intensification, urbanization and landscape fragmentation. Global changes have major impacts on biodiversity. A potential lack of response of species to selection due to environmental changes would cause an erosion of biodiversity by disrupting ecosystems sustainably. This is especially important for plants whose dispersion is on average limited in comparison to animals. In this context, one of the main challenges in ecological genomics is to identify and understand the genetics of adaptation in plants. Adding ecology to the studies of adaptive genetics will help to estimate the adaptive dynamics of plants in response to natural selection and / or changes resulting from anthropogenic environments.


Establishing the causal relationship between adaptation and genetic changes is however extremely challenging in natural systems, largely due to the difficulties in identifying ecological factors acting as selective agents. In addition, we have to keep in mind that the adaptive potential response from a plant species to global changes will not only depend on its direct interactions with the abiotic environment, but also on the environmental effects on its biotic interactions (plant-microbiota-pathobiota interactions, plant-plant interactions…). In addition, our knowledge on adaptive dynamics of organism–organism interacting systems, and more precisely on co-evolution among several interacting species, remains surprisingly very limited. This is particularly relevant when studying the recruitment of mutations in biotic partners conferring the phenotypic variant likely to be retained by natural selection.

More precisely, we aim at answering to three key transversal questions:

  1. What are the main ecological factors (climate, soil physico-chemical properties, microbiota / pathobiota, plant communities…) acting as selection agents on plants?

  2. What are the genetic and molecular mechanisms of quantitative immunity, in ecologically relevant environments?

  3. What are the genetic and molecular mechanisms driving natural variation of plant-plant interactions, in particular competition and cooperation?
