Involvement of phenolic compounds in the resistance of grapevine callus to downy mildew (Plasmopara viticola)


Callus tissue of different grapevines (Vitis spp.) was inoculated withPlasmopara viticola. Short, highly-branched hyphae with necrosis, and long hyphae with heavy sporulation were observed on resistant and susceptible callus respectively. Thin-layer chromatography and spectrophotometric analysis showed that resistant callus contained greater quantities of… (More)
