Response of vitis vinifera cell cultures to phaeomoniella chlamydospora : chang...
Lima, M. R. M.; Ferreres, F.; Dias, Alberto Carlos PiresCell suspension cultures of Vitis vinifera cv. Vinhão (Vv) were used to study the putative response of V. vinifera to Phaeomoniella chlamydospora (Pc), a fungus frequently associated with esca and grapevine decline. Cells were elicited with a Pc autoclaved biomass extract and methyl jasmonate (MeJ). Phenolic production was evaluated by HPLC-DAD and HPLC-MS/MS. Phenolic production of Vv cells significantly chang...
Expression analysis of defence-related genes in Vitis vinifera cv. Vinhão cell ...
Lima, M. R. M.; Dias, Alberto Carlos PiresEsca is a destructive disease that affects Vitis vinífera plants around the world leading to important losses in wine production. Phaeomoniella chlamydospora (Pc) is a fungus frequently associated with esca and grapevine decline. To study the defence response, specifically gene activation, of grapevine to Pc we utilized in vitro cultures of V. vinifera cv. Vinhão (Vv) elicited with fungus extract. The expressio...
Oxidative response of Vitis vinifera cells elicited with Phaeomoniella chlamydo...
Lima, M. R. M.; Dias, Alberto Carlos PiresEsca is a destructive disease that affects vineyards leading to important losses in wine production, which incidence has dramatically increased during the last few years. Phaeomoniella chlamydospora (Pc) is a fungus frequently associated with esca and grapevine decline. Information on the interaction of this fungus with Vitis plants is scarce. To study early defense mechanisms, namely the oxidat...
Differential phenolic production of Vitis vinifera cv. Alvarinho leaves affecte...
Lima, M. R. M.; Felgueiras, Mafalda; Cunha, Ana; Chicau, Gisela; Dias, Alberto Carlos PiresEsca is a destructive disease that affects Vitis vinifera around the world leading to important losses in wine production. Information on the response of Vitis vinifera plants to this disease is still scarce. To study the defence mechanisms of Vitis plants to Esca, we analysed leaves from both infected and non-affected boughs of Vitis vinifera cv. Alvarinho, of the Vinho Verde region (North of Portugal). Phenol...

Alterações na produção de compostos fenólicos em culturas de células de Vitis v...
Lima, M. R. M.; Guimarães, Orlando; Ferreres, Federico; Dias, Alberto Carlos PiresA esca é uma doença que afecta plantas da espécie Vitis vinifera levando a importantes perdas na produção de vinho. O fungo Phaeomoniella chlamydospora (PC) é frequentemente associado a plantas de videira com esca e declínio das vinhas. Informação sobre a interacção deste fungo com a esca e declínio das vinhas ainda é escassa. Para estudar mecanismos de defesa da videira ao fungo PC utilizamos culturas in vitro...
Differential phenolic production of Vitis vinifera cell cultures induced by Pha...
Lima, M. R. M.; Ferreres, Federico; Tavares, R. M.; Dias, Alberto Carlos PiresEsca is a destructive disease, of complex aetiology, that affects grapevines in several countries around the world, specially in the Mediterranean, South Africa and California (where is known as “black measles”). In the last few years the disease became a major concern given to its dramatic incidence increase. Till now, does not exist a method to treat plants attacked by Esca. To study the putative response of ...
