Contribution de la cytologie à l'étude des mécanismes de défense des plantes aux attaques parasitaires

Cette etude demontre l'apport de la biologie cellulaire a la comprehension des mecanismes de resistance des plantes aux parasites. Les techniques modernes de la cytologie moleculaire permettent de suivre le devenir d'une molecule au cours d'une interaction, d'en preciser la distribution a l'echelle des tissus et de la cellule, et de la visualiser par rapport aux sites d'infection et de localisation du parasite. Les recherches ont ete realisees sur les modeles suivants : hevea-champignon, manioc-bacterie, manioc-cochenille, cotonnier-bacterie et bananier-nematode
