Évolution des teneurs en polyamines libres et conjuguées dans les feuilles de vigne (Vitis vinifera 'Cabernet Sauvignon') saine et atteinte d'eutypiose

Abstract: Effects of Eutypa lata, the fungal agent of eutypiosis, on polyamine (putrescine (Put), spermidine (Spd), spermine (Spm), diaminopropane (Dap)) and tyramine (Tyr) contents in grapevine leaves were studied to determine the relationship between these components and disease development. The external symptoms of eutypiosis are small and necrotic leaves, which could be observed on only one arm or on two arms of the vine stock. This study was carried out on healthy leaves (S, borne by healthy vine stock), apparently… Show more

“…Pathogenic infections induce important modifications in plant PAs (Darrieumerlou et al 2001;Paschaladis et al 2001;Rifai et al 2005), that vary depending on several factors such as the nature of analyzed plant tissues, that can be locally infected or not by the pathogen, and the degree of plant tolerance to the disease. It is probable that the increase in PA levels observed in grapevine roots infected by A. mellea could have a fungal origin.…”

“…Probably, fungal PAs would not be transported out of the infected organ (Rifai et al 2005), so all the fluctuations observed in grapevine leaves would be a plant response to the root pathogen. Several authors (Belles et al 1991;Edreva 1997;Rifai et al 2004) also observed a lower concentration of free PAs as a consequence of pathogenic infections.…”

“…Polyamine levels. Polyamines were extracted according to the method described by Rifai et al (2005) and analyzed via HPLC in combination with fluorescence spectrophotometry according to the method of Smith and Davies (1985), adapted to our plant material by Geny et al (1997).…”
