Mes travaux actuels portent sur les gènes clés impliqués dans la capacité de la zone d’abscission (ZA) à se séparer cellulairement, et qui déterminent le moment de l’abscission des fruits mûrs du palmier à huile monocotylédone (Elaeis guineensis). Des études comparatives moléculaires, cellulaires, génomiques et génétiques sont menées pour comprendre la fonction de la ZA primaire multicouche d’E. guineensis.
