Activités de Recherche

Dans l’équipe FILEAS, j’étudie les processus moléculaires qui contrôlent le développement et la qualité des graines de légumineuses, notamment chez le pois, incluant ceux impliqués dans la remobilisation des nutriments des organes sources vers les graines. Je m’intéresse à l’effet du stress hydrique sur ces processus, et en collaboration avec Karine Gallardo nous étudions l’importance de la nutrition soufrée pour la réponse du pois au stress hydrique et l’élaboration de la qualité des graines (Thèse C. Henriet).
Je m’intéresse également à la qualité organoleptique des graines de légumineuses, en étudiant les processus moléculaires impliqués dans l’accumulation des molécules sources de « off-flavour » (amertume, astringence, goût végétal, …) comme les saponines ou encore les composés organiques volatiles issus de l’oxydation des acides gras par des lipoxygénases.
L’ensemble de nos travaux visent à optimiser la qualité de la graine (taille, composition protéique, « off-flavour ») et à stabiliser cette qualité sous conditions environnementales fluctuantes. Pour cela nous développons des approches de biologie intégrative basées sur l’intégration de données « omiques »,  et nous l’exploitons la variabilité génétique naturelle (GWAS) ou induite (population de mutants TILLING de pois),  en interaction avec l’équipe ECP de Judith Burstin.
