Effect of blanching, storage and drying conditions on the macro-composition, co...
Ribeiro, José Carlos; Marques, João Pedro; Fernandes, Tânia R.; Pintado, Manuela Estevez; Carvalho, Susana M. P.; Cunha, Luís MiguelFor food applications, the processing conditions applied to edible insects should present low energy requirements and environmental impact, while also assuring high quality and safety. The main goal of this study was to assess how different blanching, storage and drying conditions influence the quality and safety of Tenebrio molitor larvae. The different operations included blanching treatments (water-immersion...
Low water supply differentially affects the growth, yield and mineral profile o...
Medeiros, Janaina S.; Silva, Marta Nunes da; Carvalho, Susana M. P.; Santos, Carolos S.; Vasconcelos, Marta W.The climatic events predicted to increase in intensity and frequency in the near future, including drought, may influence the quality and productivity of several important crops for human nutrition, such as legumes. Herein, two chickpea genotypes (Cicer arietinum) were analysed for their resilience to low water supply: a commercial white chickpea (kabuli), and a black chickpea (desi) with marginal production in...
Exploring tomato phenotypic variability under combined nitrogen and water deficit
Machado, Joana; Heuvelink, Ep; Vasconcelos, Marta W.; Cunha, Luís M.; Finkers, Richard; Carvalho, Susana M. P.Background: Despite drought and nitrogen (N) deficit being two of the most important crops’ growth limiting factors, only few studies have explored tomato phenotypic variability in response to both abiotic stresses. Aims: In this study, we aimed to perform a phenotypic evaluation and an analysis of the growth traits of 40 tomato genotypes (mostly focusing on old cultivars, but also including modern hybrids and ...
The effect of silicon on the antioxidant system of tomato seedlings exposed to ...
Machado, Joana; Fernandes, Ana Patricia G.; Bokor, Boris; Vaculík, Marek; Heuvelink, Ep; Carvalho, Susana M. P.; Vasconcelos, Marta W.Exploring sustainable strategies for improving crop water and nitrogen use efficiency is essential. Silicon (Si) has been reported as a beneficial metalloid for plants since it alleviates several abiotic stresses (including drought) by triggering the plants´ antioxidant system. However, its role in mitigating the negative impact of nitrogen (N) deficit alone or when combined with water (W) deficit is not well s...
Impact of soybean-associated plant growth-promoting bacteria on plant growth mo...
Roriz, Mariana; Pereira, Sofia I. A.; Castro, Paula M. L.; Carvalho, Susana M. P.; Vasconcelos, Marta W.Conventional strategies to manage iron (Fe) deficiency still present drawbacks, and more eco-sustainable solutions are needed. Knowledge on soybean-specific diversity and functional traits of their plant growth-promoting bacteria (PGPB) potentiates their applicability as bioinoculants to foster soybean performance under calcareous soil conditions. This work aimed to assess the efficacy of PGPB, retrieved from s...
Enzymatic and non-enzymatic antioxidant responses of young tomato plants (cv. m...
Machado, Joana; Vasconcelos, Marta W.; Soares, Cristiano; Fidalgo, Fernanda; Heuvelink, Ep; Carvalho, Susana M. P.This study aims to perform a broad analysis of the antioxidant (AOX) responses of young tomato plants exposed to single and combined mild nitrogen (N) and water deficits through the evaluation of oxidative biomarkers, non-enzymatic and enzymatic AOX components. ‘Micro-Tom’ seedlings were subjected to four treatments: control (CTR; 100%N + 100%W), N deficit (N; 50%N), water deficit (W; 50%W), and combined defici...
Nutritional evaluation of flour obtained from Tacca leontopetaloides used as an...
Uachisso, Arminda; Silva, Marta Nunes da; Agostinho, Daniel; Pinho, Olívia; Vasconcelos, Marta W.; Carvalho, Susana M. P.Tubers from wild Tacca leontopetaloides plants are frequently used as a food commodity, but when consumed raw it has a bitter taste and can be toxic, thus threatening food security. This study aimed to evaluate the nutritional composition of flour from T. leontopetaloides subjected to distinct washing treatments, hoping to improve its suitability as a pivot food commodity in regions affected by poverty and food...
Scientific and technological advances in the development of sustainable disease...
Santos, Miguel G.; Silva, Marta Nunes da; Vasconcelos, Marta W.; Carvalho, Susana M. P.Plant disease outbreaks are increasing in a world facing climate change and globalized markets, representing a serious threat to food security. Kiwifruit Bacterial Canker (KBC), caused by the bacterium Pseudomonas syringae pv. actinidiae (Psa), was selected as a case study for being an example of a pandemic disease that severely impacted crop production, leading to huge economic losses, and for the effort that ...
Mitigation of emergent bacterial pathogens using pseudomonas syringae pv. Actin...
Silva, Marta Nunes da; Santos, Miguel G.; Vasconcelos, Marta W.; Carvalho, Susana M. P.Globalization propelled human migration and commercial exchanges at the global level, but woefully led to the introduction of non-indigenous organisms into several agroecological systems. These include pathogenic bacteria with devastating consequences for numerous crops of agronomical importance for food production worldwide. In the last decade, research efforts have focused on these noxious organisms, aiming t...
Effect of different pre-inoculation procedures on leaf spotting appearance in a...
Santos, Miguel G.; Silva, Marta Nunes da; Gallego, Pedro P.; Vasconcelos, Marta W.; Carvalho, Susana M. P.Phytopathology studies most often rely on laboratory, greenhouse or field experiments in which plants are artificially inoculated using a variety of pre-inoculation procedures that aim to improve plant infection success. Concerning the Kiwifruit Bacterial Canker (KBC), whose aetiological agent is the bacterium Pseudomonas syringae pv. actinidiae (Psa), the pre-inoculation procedures most often target leaf tissu...
