[EN] In the present work, we have looked for the nature of the phenylpropanoids biosynthesized during the plant-pathogen reaction of two systems, Cucumis sativus and Cucumis melo infected with either prunus necrotic ringspot virus (PNRSV) or melon necrotic spot virus (MNSV), respectively. An accumulation of p-coumaric, caffeic and/or ferulic acids was observed in infected plant extracts hydrolysed with P-glucosidase or esterase. Analysis of undigested samples by HPLC/ESI revealed that these compounds are mainly forming esters with glucose: 1-O-coumaroyl-beta-glucose, 1-O-caffeoyl-beta-glucose, and 1-O-fer-uloyl-beta-glucose. Cinnamic acid 4-hydroxylase (C4H, EC ...
