Histolocalisation of phenolic compounds in plant-parasite interactions in sunflower and grapevine

Histolocalisation of phenolic compounds in plant-parasite interactions in sunflower and grapevine

Phenolic compounds were studied histochemically before, during and after infection in Helianthus resinosus (a wild sunflower chosen for high resistance to Sclerotinia sclerotiorum) with S. sclerotiorum, and 3 Vitis spp. with Plasmopara viticola. Microscopical observations after marking cross-sections with different coloured and fluorescent probes showed the presence of phenolic compounds (hydroxycinnamic and gallic derivatives) before infection in resistant species.
