Cultura da alfarrobeira – uma aposta na sustentabilidade agrícola do Alentejo
Cardoso, Hélia; Marques, Mónica; Rodrigues, Lénia; Campos, Catarina; Pires, Rita; Rato, Ana Elisa; Peixe, AugustoA alfarrobeira, reconhecida pela sua resistência a condições ambientais adversas e pelo elevado valor económico dos seus frutos, tem potencial para se afirmar como uma cultura estratégica no Alentejo, contribuindo simultaneamente para a diversificação agrícola, para a valorização dos recursos genéticos nacionais e para a promoção de práticas agrícolas mais sustentáveis e resilientes às alterações climáticas.
Applicability of metabolomics to improve sustainable grapevine production
Estêvão, Catarina; Rodrigues, Lénia; Rato, Ana Elisa; Garcia, Raquel; Cardoso, Hélia; Campos, CatarinaMetabolites represent the end product of gene expression, protein interaction and other regulatory mechanisms. The metabolome reflects a biological system’s response to genetic and environmental changes, providing a more accurate description of plants’ phenotype than the transcriptome or the proteome. Grapevine (Vitis vinifera L.), established for the production of wine grapes, table grapes, and raisins, holds ...
Metabolomics Connecting Genomes and Phenomes in Plant Molecular Breeding—A Spec...
Rodrigues, Lénia; Estêvão, Catarina; Garcia, Raquel; Rato, Ana Elisa; Campos, Catarina; Marques, Mónica; Pires, Rita; Peixe, Agusto; Cardoso, HéliaThe interest in Mediterranean species has grown exponentially in recent decades, driven by their distinctive organoleptic properties and the high content of bioactive compounds beneficial to human health. This study presents a comprehensive review of current knowledge on the alterations in metabolomic profiles associated with the biosynthesis of functional metabolites in response to abiotic stressors, namely sa...
Exploring the involvement of the somatic embryogenesis receptor kinase (SERK) g...
Pires, Rita; Marques, Diogo; Campos, Catarina; Peixe, Augusto; Cardoso, HéliaSeveral Portuguese olive tree cultivars are characterized by their high-quality oils, which explains their use on the production of DOP (Denomination of Protect Origin) olive oil brands. However, some of those cultivars are affected by serious agronomic problems, including high susceptibility to biotic and abiotic stresses, excessive vigour, and low ability to adventitious root formation, which strongly limits ...
A TaqMan® assay allows an accurate detection and quantification of Fusarium spp...
Campos, Maria Doroteia; Varanda, Carla; Materatski, Patrick; Patanita, Mariana; Ribeiro, Joana Amaro; Albuquerque, André; Campos, CatarinaIn tomato plants, Fusarium spp. have been increasingly associated with several wilt and rot diseases that are responsible for severe yield losses. Here, we present a real-time PCR TaqMan® MGB (Minor Groove Binder) assay to detect and discriminate Fusarium spp. from other fungal species that affect tomato plants. The methodology used is based on the selective amplification of the internal transcribed spacer (ITS...
TaqMan Probes for Plant Species Identification and Quantification in Food and F...
Campos, Maria Doroteia; Campos, Catarina; Cardoso, HéliaIn the last few years, the traceability and labeling of processed food and feeds have gained increasing importance due to the impact that mislabeling and product fraud may have on human/animal health or on the quality of final products, such as milk, cheese, and meat, as a consequence of animal dietary. The presence of contaminants or possible frauds due to the use of alternative plant materials in food and fee...
The Incidence of Guillain-Barré Syndrome during COVID-19 Pandemic: A Portuguese...
Vítor, Joana; Moniz Dionísio, Joana; Campos, Catarina; Oliveira Santos, Miguel; Cruz, Simão; Castelo, Juliana; Castro, José; Castro, IsabelIntroduction: Guillain-Barré syndrome (GBS) is a rare peripheral nervous system inflammatory disease with an annual estimated incidence of 1-2/100 000. Several studies relate GBS with vaccination, especially against influenza. The literature is discordant on GBS incidence during the pandemic. Additionally, while vaccination is globally ongoing, GBS cases have been associated with an inoculation against SARS-CoV...
Secondary bioactive metabolites from foods of plant origin as theravention agen...
Gomes, Telma Marisa; Sousa, Patrícia; Campos, Catarina; Perestrelo, Rosa; Câmara, José S.; Gomes, Telma; Perestrelo, Rosa<jats:p>Neurodegenerative disorders (NDDs) such as Alzheimer’s (AD) and Parkinson’s (PD) are on the rise, robbing people of their memories and independence. While risk factors such as age and genetics play an important role, exciting studies suggest that a diet rich in foods from plant origin may offer a line of defense. These kinds of foods, namely fruits and vegetables, are packed with a plethora of powerful ...
qPCR as a sensitive tool for detecting Fusarium spp. in tomato plants
Campos, Maria Doroteia; Varanda, Carla; Patanita, Mariana; Ribeiro, Joana A.; Campos, Catarina; Materatski, Patrick; Albuquerque, André; Osa, NicolásThe need to increase food production together with the demand to reduce the application of synthetic chemicals that have consequences on increasing the carbon footprint and negative impacts on the environment and human health, led to the search for alternative methods to protect plants against pathogens. The use of the highly sensitive real-time quantitative PCR (qPCR) arises as an extremely useful tool for stu...
Identification of candidate genes involved in olive response to anthracnose for...
Inácio, Diogo; Félix, M.R.; Campos, Catarina; Patanita, Mariana; Ribeiro, Joana A.; Varanda, Carla; Materatski, Patrick; Albuquerque, AndréAnthracnose is a disease that affect the olive tree caused by fungi of the genus Colletotrichum. These fungi are responsible to premature fruit drop and a consequent decrease in the oil quality, and also cause defoliation of trees compromising the production of the following years. Currently the best control strategy is based on application of synthetic fungicides, with a regulatory pressure in agriculture worl...
