PROJETS DE RECHERCHE
L’équipe « Sunflower-Pests Interactions » s’intéresse à identifier et comprendre les mécanismes de résistance à l’orobanche du tournesol (Orobanche cumana). O. cumana est une plante parasite obligatoire. Sans racines et incapable de réaliser la photosynthèse, elle se développe au dépend du tournesol en détournant l’eau et les éléments nutritifs. Jusqu’à une centaine d’orobanches peuvent se fixer sur un seul pied de tournesol. Les pertes de rendement peuvent aller de 20% à 100% en fonction du niveau d’infestation du champ, du niveau d’agressivité et de virulence de la population. O. cumana est présente de la Chine au sud de l’Espagne.
Nous utilisons des approches de génétique, de génomique et de biologie fonctionnelle pour comprendre l’expression des résistances et le dialogue moléculaire et cellulaire entre le tournesol et l’orobanche. Les gènes de résistance présents dans les hybrides cultivés de tournesol sont rapidement contournés, aussi, nous nous intéressons à caractériser la diversité des populations mondiales d’orobanche pour comprendre leur évolution. De façon remarquable, alors que le tournesol a été domestiqué sur le continent nord-américain, O. cumana n’est pas présente sur le continent américain.
Nous travaillons aussi de façon plus marginale sur la résistance au mildiou du tournesol (Plasmopara halstedii, oomycète obligatoire) pour identifier et caractériser des résistances quantitatives et développer des outils de génotypage pour caractériser les souches.
Optimildiou (2020-Plant2Pro, coord.: E. Mestries et S. Muños): le projet vise (i) à développer des marqueurs moléculaires à partir des données génomiques produites dans le cadre des projets Effectores et EVOPLASMO et du séquençage de 10 nouvelles souches dans le cadre de Optimilidou et (ii) à mieux caractériser les nouvelles souches émergentes.
Omoco (2020-2021, Labex Tulip/MAS SEEDS: Coord.: C. Seassau et S. Muños):
ResODiv (2019-2021, Promosol, coord. : M. Chabaud) : exploitation de la diversité génétique chez les Helianthus sauvages pour la recherche de nouvelles résistances à la plante parasite Orobanche cumana, et leur utilisation en pre-breeding.
