Grapevine species (Vitis sp.) are prone to several diseases, fungi being the major pathogens compromising its cultivation and economic profit around world. Knowledge of complexity mechanisms responsible for resistance fungus infection cultivars, such as Regent, is necessary strategies be defined which will improve in highly susceptible crop species. Transcript metabolic profiles Vitis vinifera cultivars Regent Trincadeira (resistant fungi, respectively) were analysed by cDNA microarray,...
Subtilisin-like proteases (subtilases) are serine that fulfill highly specific functions in plant development and signaling cascades. Over the last decades, it has been shown several subtilases specifically induced following pathogen infection very recently an Arabidopsis subtilase (SBT3.3) was hypothesized to function as a receptor located plasma membrane activating downstream immune processes. Despite their prevalence potential relevance regulation of defense mechanisms crop improvement,...
Amid climate change, heatwave events are expected to increase in frequency and severity. As a result, yield losses viticulture due stress have increased over the years. one of most important crops world, an eco-friendly mitigation strategy is greatly needed. The present work aims evaluate physiological fitness improvement by two marine plant growth-promoting rhizobacteria consortia Vitis vinifera cv. Antão Vaz under conditions. To assess potential biophysical biochemical thermal feedback...
The pivotal role of cultivated grapevine (Vitis vinifera L.) in many countries economy is compromised by its high susceptibility to Plasmopara viticola, the causal agent downy mildew disease. Recent research has identified a set genes related resistance which may be used track infection. Quantification expression these requires normalizing qPCR data using reference with stable system studied. In this study, eleven (VATP16, 60 S, UQCC, SMD3, EF1α, UBQ, SAND, GAPDH, ACT, PsaB, PTB2) was...
Plant resistance to biotrophic pathogens is classically believed be mediated through salicylic acid (SA) signaling leading hypersensitive response followed by the establishment of Systemic Acquired Resistance. Jasmonic (JA) has extensively been associated defense against necrotrophic and insects inducing accumulation secondary metabolites PR proteins. Moreover, it that plants infected with fungi suppress JA-mediated responses. However, recent evidences have shown certain fungal species also...
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...
Abstract Vitis vinifera , one of the most cultivated fruit crops, is susceptible to several diseases particularly caused by fungus and oomycete pathogens. In contrast, other species (American, Asian) display different degrees tolerance/resistance these pathogens, being widely used in breeding programs introgress resistance traits elite V. cultivars. Secondary metabolites are important players plant defence responses. Therefore, characterization metabolic profiles associated with disease...
Regenerative agriculture aims to boost native biodiversity and ensure sustainable production. Plant Growth Promoting Bacteria (PGPB) enhance crop yield through improved nutrient use efficiency or stress tolerance. Utilizing synthetic bacterial communities (SynCom) tailored specific challenges holds promise for enhancing plant resilience. However, include designing microbial consortia selecting SynCom application techniques. This study tested four PGPB methods on tomato plants evaluate their...
Abstract Proteases are essential enzymes in plants that play multiple roles immunity, including molecular recognition, programmed cell death, and the degradation of pathogen proteins. During plant-pathogen interactions, both organisms have evolved mechanisms to regulate protease activity. Plants produce specific inhibitors prevent excessive or harmful proteolysis, while pathogens counteract these defenses by deploying molecules block proteases weaken plant immunity. Despite significant...
Ectomycorrhizal symbiosis is essential for the life and health of trees in temperate boreal forests where it plays a major role nutrient cycling functioning forest ecosystem. Trees with ectomycorrhizal root tips are more tolerant to environmental stresses, such as drought, biotic stresses pathogens. Detailed information on these molecular processes understanding symbiotic tissue development order optimize benefits this natural phenomenon. Next generation sequencing tools allow analysis non...
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...
