Metagenomic analysis of the effects of plant- and yeast-based formulations on t...
Monteiro, Eliana; Baptista, Paula; Silva, Sofia; Carvalho, Márcia; Bragança, Radek; Guinan, Kieran J.; Sujeeth, Neerakkal; Cortez, IsabelGrapevine is highly susceptible to fungal diseases such as downy mildew and powdery mildew, which are traditionally managed through the intensive use of chemical fungicides. However, in the context of increasingly sustainable viticulture, biofungicides derived from plant and yeast extracts are gaining attention. Despite this, their impact on the grapevine leaf microbiome, crucial for plant health and disease re...
Exploring seaweed and Glycine Betaine Biostimulants for enhanced phenolic conte...
Monteiro, Eliana Maria Ribeiro; De Lorenzis, Gabriella; Ricciardi, Valentina; Baltazar, Miguel; Pereira, Sandra; Correia, Sofia Mendes MoreiraClimate change will pose a challenge for the winemaking sector worldwide, bringing progressively drier and warmer conditions and increasing the frequency and intensity of weather extremes. The short-term adaptation strategy of applying biostimulants through foliar application serves as a crucial measure in mitigating the detrimental effects of environmental stresses on grapevine yield and berry quality. The aim...
Ascophyllum nodosum extract and glycine betaine preharvest application in grape...
Monteiro, Eliana Maria Ribeiro; Baltazar, Miguel; Pereira, Sandra; Correia, Sofia Mendes Moreira; Ferreira, Helena; Alves, Fernando; Gonçalves, BertaThe Douro Demarcated Region (DDR) has peculiar edaphoclimatic characteristics that provide a suitable terroir for premium wine production. As climate change effects continue to emerge, ensuring productivity and quality becomes increasingly important for viticulturists, as those directly determine their profits. Cultural approaches, such as the use of biostimulants, are actively being developed to mitigate abiot...
Cowpea immature pods and grains evaluation: an opportunity for different food s...
Carvalho, Márcia; Sobreira, Carla; Barros, Ana; Coutinho, João; Rosa, Eduardo; Castro, Isaura; Carnide, ValdemarCurrently, the sustainability of agro-food systems is one of the major challenges for agriculture and the introduction of new pulse-based products can be a good opportunity to face this challenge. Cowpea (Vigna unguiculata L. Walp.) is a nutritionally important crop and has the particularity that the aerial section of the plant is entirely edible. The current research determines the nutritional composition of t...
The role of Biostimulants as Alleviators of Biotic and Abiotic Stresses in Grap...
Monteiro, Eliana Maria Ribeiro; Gonçalves, Berta; Castro, Isaura; Cortez, IsabelThe viticulture and wine industry contribute to the economy and reputation of many countries all over the world. With the predicted climate change, a negative impact on grapevine physiology, growth, production, and quality of berries is expected. On the other hand, the impact of these changes in phytopathogenic fungi development, survival rates, and host susceptibility is unpredictable. Grapevine fungal disease...
Detection of glucosinolate metabolite pathway using SSR markers of Brassica ole...
Ammar, H. Ben; Sdouga, D.; Di Bella, M. C.; Treccarichi, S.; Cali, R.; Branca, Ferdinando; Marghali, S.; Rosa, Eduardo; Castro, IsauraThe use of genetic approaches to analyse the genetic variation associated with morphological and biochemical differences has greatly facilitated the improvement of agronomic traits. In this context, the aim of this research was to associate glucosinolates (GLS) profile of Brassica oleracea complex species (n=9) core collection with SSR markers. In this study, we have analysed several accessions belonging to 4 l...
Organic farming production of broccoli genotypes in northern Portugal
Carvalho, M.; Pereira, Â.; Caldas, F.; Branca, Ferdinando; Rosa, Eduardo; Castro, Isaura; Carnide, ValdemarThe BRESOV project intends to encourage sustainable agriculture preserving the biodiversity and promote the development of broccoli adapted to climate changes. Four broccoli genotypes, ‘CN-BRO-09’, ‘Heraklion’, ‘Naxos’ and ‘Rasmus’, adaptation to a Portuguese organic farming system were evaluated in an organic farm located in Braga, northern Portugal (41.32’18”N, 8.24’00”W). The soil was prepared on 16 ridges o...
Pervasive hybridization with local wild relatives in Western European grapevine...
Freitas, Sara; Gazda, Małgorzata A; Rebelo, Miguel Â; Muñoz-Pajares, Antonio J; Vila-Viçosa, Carlos; Muñoz-Mérida, Antonio; Gonçalves, Luís MGrapevine (Vitis vinifera L.) diversity richness results from a complex domestication history over multiple historical periods. Here, we used whole-genome resequencing to elucidate different aspects of its recent evolutionary history. Our results support a model in which a central domestication event in grapevine was followed by postdomestication hybridization with local wild genotypes, leading to the presence ...
