Grapevine downy mildew, caused by the biotrophic oomycete Plasmopara viticola, is one of most important diseases in modern viticulture. The search for sustainable disease control measure extreme importance, thus becoming imperative to fully characterize mechanisms leading an incompatible interaction. We have previously shown that lipid signalling events play role grapevine's response this pathogen, namely through changes linolenic acid content, peroxidation and jasmonic synthesis. Here, we...
Agricultural by-products are often hidden sources of healthy plant ingredients. The investigation the nutritional values these is essential towards sustainable agriculture and improved food systems. In vine industry, grape leaves a bulky side product which strategically removed treated as waste in process wine production. this work we performed an untargeted metabolomic profiling methanol extract Vitis vinifera cultivar 'Pinot noir', analysed their fatty acid content, estimated antioxidative...
The widespread use of pesticides in agriculture remains a matter major concern, prompting critical need for alternative and sustainable practices. To address this, the lipid-derived molecules as elicitors to induce defence responses grapevine plants was accessed. A Plasmopara viticola fatty acid (FA), eicosapentaenoic (EPA) naturally present oomycetes, but absent plants, applied by foliar spraying leaves susceptible cultivar (Vitis vinifera cv. Trincadeira), while host lipid derived...
Grapevine downy mildew, caused by the biotrophic oomycete Plasmopara viticola, is one of most severe and devastating diseases in viticulture. Unravelling grapevine defence mechanisms crucial to develop sustainable disease control measures. Here we provide new insights concerning fatty acid’s (FA) desaturation, a fundamental process lipid remodelling signalling. Previously, have provided evidence that signalling essential establishment incompatible interaction between viticola. In first hours...
The domesticated species Vitis vinifera L. harbours many cultivars throughout the world that present distinctive phenology and grape quality. Not only have grapes been used for human consumption, but leaves are also as a source of bioactive compounds in diets several Mediterranean countries. We selected seven different performed elemental, fatty acid (FA) pigment profiling. Total reflection X-ray fluorescence (TXRF) enabled identification 21 elements. Among them, Na, Ca K were highly...
Grapevine is susceptible to several diseases, being downy mildew, caused by Plasmopara viticola, among the most devastating. Control strategies include application of pesticides every season through almost all grapevine developmental stages, jeopardizing viticulture sustainability. Understanding resistance molecular processes crucial define alternative and select disease traits. Identifying markers that discriminate between tolerant genotypes P. viticola an important step. It shown lipids...
Grapevine is one of the most important fruit crops worldwide, being Portugal top wine producers. It well established that sensory characteristics from a particular region are defined by physiological responses grapevine to its environment and thus, concept terroir in viticulture was established. Among all factors contribute definition, soil microorganisms play major role nutrient recycling drastic influence on plant fitness (growth protection) course production. Soil microbiome four...
Vitis vinifera L. is highly susceptible to the biotrophic pathogen Plasmopara viticola. To control downy mildew disease, several phytochemicals are applied every season. Recent European Union requirements reduce use of chemicals in viticulture have made it crucial alternative and more sustainable approaches this disease. Our previous studies pinpoint role fatty acids lipid signalling establishment an incompatible interaction between grapevine P. further understand mechanisms behind...
ABSTRACT Here, we report a draft metagenome-assembled genome and annotation of Pseudomonas sp. obtained from the sequenced Vaucheria bursata . The completeness was 97.9% with total 5,322 open reading frames, which 3,147 genes were annotated. availability metagenome will elucidate possible epiphytic interactions bacteria
The reduction of phytochemicals used to control pests and diseases is one the demands on modern agriculture. Grapevine most important crops grown in temperate climates, where Europe's wine industry represents 40% world production. cultivated grapevine, Vitis vinifera, prone several diseases, with downy mildew being among devastating. Preventive fungicide applications are each growing season disease incidence, major environmental economic constraints. A deeper knowledge grapevine-Plasmopara...
Subtilases are serine peptidases involved in several plant biological functions, however one of their most important participation is the response to biotic and abiotic stresses. have been linked hormone-associated signalling, like jasmonic acid (JA) pathway, that particularly related with defence responses against necrotrophic fungus herbivores. In grapevine, recent studies implicated JA pathway Plasmopara viticola, a biotrophic oomycete. Our more results showed an increased expression...
The reduction of pesticide use to control pests and diseases is one modern agriculture’s demands. In the grapevine-Plasmopara viticola pathosystem, repeated preventive applications fungicides occur during vegetative period. identification specific mechanisms or molecules with bioactive fungicide properties may lead new disease strategies. Following an omics-based system biology approach we were able identify both subtilisin-like proteases lipid associated signalling events as key players on...
