The use of Sentinel 2 to quantify N, Ca, and K in walnut orchards
Mendes, Maria Beatriz; Farinha, Daniela; Oliveira, Pedro; Mota Barroso, João; Rato, Luís Miguel; Sousa, Adélia; Rato, Ana Elisa’Persian walnut’ (Juglans regia L.) is one of the most consumed nut species in the world, and N, K, and Ca nutrition are critical for its growth and quality. Mineral nutrition management in fruit crops over large areas is a challenging task only possible with a remote sensing data approach and using rapid analytical methods to correlate remotely sensed data with ground data. This study aims to develop and valid...
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...
The Influence of (Poly)phenol Intake in Saliva Proteome: Short- and Medium-Term...
Louro, Teresa; Carreira, Laura; Caeiro, Inês; Simões, Carla; Ricardo-Rodrigues, Sara; Rato, Ana Elisa; Capela e Silva, Fernando; Luis, HenriqueThe relationship between salivary proteome and dietary habits was studied in previous works, where a relationship between salivary proteins like cystatins and polyphenol/tannin levels in diet was observed. However, it remains to be elucidated if this association results from an effect of polyphenol-rich food ingestion on saliva composition. The aim of this work was to test the effects of apple intake on the sal...
Climate Effect on Morphological Traits and Polyphenolic Composition of Red Wine...
Rouxinol, Maria Inês; Martins, Maria Rosário; Salgueiro, Vanda; Costa, Maria João; Barroso, João; Rato, Ana ElisaWine quality is determined by the development of grape maturation, which is highly dependent on climate variations. Extreme weather events are becoming more common, which will affect the productivity and quality of grapes and wine. Grape development depends on many factors, including weather, and extreme events will influence berry size, skin thickness and the development of some key compounds, such as phenolic...
Estudo sobre a origem do enrugamento do miolo da noz
Farinha, Daniela; Mendes, Maria; Mota Barroso, João; Peixe, Augusto; Dias, António; Rato, Ana ElisaA Nogueira (Juglans regia L.) é uma das espécies de frutos secos mais consumidas que tem vindo a ganhar importância com a implantação de novos pomares de Norte a Sul do país. A formação incompleta da semente, com o enrugamento do miolo associado, é um dos problemas que deprecia a qualidade e para o qual não existe um controle eficaz por se desconhecer a sua origem. A acumulação das reservas ao nível da semente ...
Exploring the applicability of calorespirometry to assess seed metabolic stabil...
Rodrigues, Lénia; Nogales, Amaia; Hansen, Lee; Santos, Fátima; Rato, Ana Elisa; Cardoso, HéliaThe availability of phenotyping tools to assist breeding programs in the selection of high-quality crop seeds is of obvious interest with consequences for both seed producers and consumers. Seed germination involves the activation of several metabolic pathways, such as cellular respiration to provide the required ATP and reducing power. This work tested the applicability of calorespirometry, the simultaneous me...
Comparative study on the use of three different near infrared spectroscopy reco...
Nogales-Bueno, Julio; Feliz, Luis; Baca-Bocanegra, Berta; Hernandéz-Hierro, José Miguel; Heredia, Francisco José; Mota Barroso, João ManuelWalnut fruit (Juglans regia L.) is an internationally well-known product with an important tradition of consumption. Its health benefits and economic importance in the food industry make this nut an interesting research topic. In this feasibility study, 200 walnut samples of 5 different varieties were collected and their near infrared (NIR) spectra were recorded with 3 different devices: a benchtop Fourier tran...
Assessment of Total Fat and Fatty Acids in Walnuts Using Near-Infrared Hyperspe...
Nogales-Bueno, Julio; Baca-Bocanegra, Berta; Hernández-Hierro, José Miguel; Garcia, Raquel; Mota Barroso, João; Heredia, Francisco José; Rato, Ana Elisa“Persian” walnut (Juglans Regia L.) is one of the most consumed tree nuts in the world. It is rich in several bioactive compounds, with polyunsaturated and monounsaturated fatty acids (PUFA and MUFA) appearing at high concentrations. Walnut consumption protects against cardiovascular, carcinogenic, and neurological disorders. The fatty acid profile has usually been determined by gas chromatography, a reliable a...
Utilização de dados do satélite Sentinel-2e de espectroscopia NIR para a quanti...
Mendes, Maria Beatriz; Farinha, Daniela; Sousa, Adélia; Barroso, João Manuel; Peixe, Augusto; Rato, Luis Miguel; Dias, António; Rato, Ana ElisaA determinação do teor de nutrientes em culturas agrícolas requer periodicidade na colheita de amostras foliares que serão futuramente analisadas em laboratórios acreditados para o efeito. Desta forma, são disponibilizadas aos agricultores recomendações de fertilização baseadas nos resultados das análises foliares. Este processo é moroso e requer uma recolha representativa das amostras principalmente em parcel...
