Harnessing lipids
Laureano, GonçaloGrapevine (Vitis vinifera L.) is one of the most extensively cultivated plants worldwide. However, the majority of Vitis vinifera cultivars used in the wine industry exhibit high susceptibility to diseases such as grapevine downy mildew, which is caused by the obligate biotrophic oomycete, Plasmopara viticola. To control this disease, viticulturers often resort to the preventive use of phytochemicals throughout...
A New Perspective for Vineyard Terroir Identity: Looking for Microbial Indicato...
Cruz-Silva, Ana; Laureano, Gonçalo; Pereira, Marcelo; Dias, Ricardo; Silva, José Moreira da; Oliveira, Nuno; Gouveia, Catarina; Cruz, CristinaGrapevine is one of the most important fruit crops worldwide, being Portugal one of the top wine producers. It is well established that wine sensory characteristics from a particular region are defined by the physiological responses of the grapevine to its environment and thus, the concept of terroir in viticulture was established. Among all the factors that contribute to terroir definition, soil microorganisms...
Accessing the link between subtilases and lipid signalling events in grapevine ...
Figueiredo, Joana; Laureano, Gonçalo; Silva, Clemente da; Maia, Marisa; Silva, Marta Sousa; Figueiredo, AndreiaSubtilases are serine peptidases involved in several plant biological functions, however one of their most important participation is in the response to biotic and abiotic stresses. Subtilases have been linked to hormone-associated signalling, like the jasmonic acid (JA) pathway, that is particularly related with defence responses against necrotrophic fungus and herbivores. In grapevine, recent studies have imp...
Subtilisin-like proteases and lipid signalling events play an important role in...
Figueiredo, Andreia; Figueiredo, Joana; Maia, Marisa; Cavaco, Ana Rita; Laureano, Gonçalo; Nascimento, Rui; Silva, Clemente da; Matos, Ana RitaThe reduction of pesticide use to control pests and diseases is one of modern agriculture’s demands. In the grapevine-Plasmopara viticola pathosystem, repeated preventive applications of fungicides occur during the vegetative period. The identification of specific mechanisms or molecules with bioactive fungicide properties may lead to new disease control strategies. Following an omics-based system biology appro...
The interplay between membrane lipids and phospholipase A family members in gra...
Laureano, Gonçalo; Figueiredo, Joana; Cavaco, Ana Rita; Duarte, Bernardo; Caçador, Isabel; Malhó, Rui; Sousa Silva, Marta; Matos, Ana RitaGrapevine downy mildew, caused by the biotrophic oomycete Plasmopara viticola, is one of the most important diseases in modern viticulture. The search for sustainable disease control measure is of extreme importance, thus becoming imperative to fully characterize the mechanisms leading to an incompatible interaction. We have previously shown that lipid signalling events play an important role in grapevine's res...
