L’équipe ‘Epidémiologie végétale et vection’ (Epi2V) conduit des recherches sur les processus de dissémination de maladies de plantes transmises par vecteurs aériens. Nos travaux s’articulent autour de trois axes correspondant i) à l’analyse de la diversité biologique et moléculaire des populations de pathogènes et de leurs vecteurs, ii) à l’étude des processus d’adaptation et d’évolution impliqués dans les interactions spécifiques entre les pathogènes, leurs vecteurs et leurs hôtes (sauvages et cultivés) et iii) au développement de modèles permettant d’expliquer et/ou de simuler la dynamique spatio-temporelle des pathosystèmes.

Pour mener nos actions de recherche, nous travaillons de manière complémentaire sur trois agents phytopathogènes : deux virus, le Plum pox virus (PPV, Potyvirus) et le Wheat dwarf virus (WDV, Mastrevirus) responsables respectivement de la sharka sur Prunus et du pied chétif du blé, et un phytoplasme, ‘Candidatus Phytoplasma prunorum’ à l’origine de l’enroulement chlorotique de l’abricotier. Les études sur ces pathogènes de plantes nous permettent de couvrir une large gamme de variation des paramètres biologiques impliqués dans l’épidémiologie de maladies transmises par vecteurs aériens : gammes d’hôtes (pérenne vs. annuelle), dynamiques de transmission (non-persistant vs. persistant) et types de vecteurs (pucerons vs. psylles vs. cicadelles).

Ainsi, notre approche consiste à identifier les facteurs majeurs de la dynamique de ces pathosystèmes par des méthodes complémentaires en prenant en compte les sources d’inoculum, la fréquence et les distances de dissémination, et l’adaptation des populations de pathogènes à un contexte agronomique donné. A travers cette démarche scientifique, notre ambition est de faire converger biologie évolutive, épidémiologie moléculaire et modélisation en rapprochant les travaux conduits à l’échelle de la plante (niveau de caractérisation des propriétés biologiques des pathogènes) avec ceux entrepris aux échelles supérieures (de la parcelle au territoire régional, niveaux de compréhension de la dynamique d’expansion des épidémies sous l’action des vecteurs et des activités humaines).
