Domaine de recherche

Je travaille sur les interactions porte-greffe/greffon chez la vigne et leurs effets sur les caractéristiques développementales de la plante entière. Les effets des porte-greffes sur la croissance du greffon s’appellent vigueur conférée, ils sont bien connus par les viticulteurs mais très peu étudiés et peu caractérisés. Nous cherchons à identifier les mécanismes qui contrôlent ce phénomène mais ils sont encore largement inconnus. Chez les espèces fruitières ligneuses où le greffage est un élément clef du système cultural, ces interactions sont un frein à l'amélioration génétique, puisque de nombreuses propriétés de l'assemblage ne peuvent être déduites des propriétés individuelles des partenaires.

Ma recherche a débuté en été 2009 avec la caractérisation de la vigueur conférée de jeunes plants de Cabernet Sauvignon greffé sur les porte-greffes qui confèrent soit une vigueur forte (1103 Paulsen) soit une vigueur faible (Riparia Gloire de Montpellier) avec le témoin Cabernet Sauvignon greffé sur Cabernet Sauvignon. J'ai fait une analyse détaillée de croissance des feuilles, pétioles, vrilles et tiges du greffon Cabernet Sauvignon à l’échelle de l'organe et de la cellule. Cette caractérisation a été complémentée par les analyses transcriptomiques des méristèmes apicaux de la tige et les analyses biochimiques des feuilles et des tiges. Nous essayerons également de faire une analyse des microARNs présents dans la sève élaborée afin d'identifier si les ARN qui circulent dans le phloème sont impliqués dans le contrôle de vigueur conférée chez la vigne.
