Activity of research

The objectives of my work are:

(i) to assess the impact of soil water stress on the regulating services associated with legume-microorganism interactions in the soil,

(ii) to evaluate the cost-benefit ratio of the interaction for each of the partners,

(iii) ultimately offer legume genotypes that best enhance beneficial interactions.

To that aim, I am developing an integrative biology approach (multi-disciplinary and multi-scale) allowing to prioritize the ecophysiological, metabolic and molecular processes which could be targets for the conception of more stable legume ideotypes under fluctuating soil water conditions.


My research activities are organized around 3 main topics:

1 / Identification of ecophysiological mechanisms allowing the plant to harden during recurrent water stress periods.

On-going projects: FUI Eauptic 2018-2021 ; Projet Ressourcement Plant2Pro-ARECOVER (2020-2022) ; Conventions Terres Inovia (2016-2019).

2 / Comparative ecophysiology in annual legumes in response to a combination of abiotic stresses.

On-going projects: FP7-LEGATO (2013-2018); H2020-EUCLEG (2017-2021)

3 / Interaction between plasticity of the root system and plasticity of soil microbial communities.

On-going projects: INRAE-AgroEnv (2019-2020)
