OptoBrain: A Wireless Sensory Interface for Optogenetics
Andrade, Rodrigo; Oshiro, Helder Eiki; Ginja, Gabriel Augusto; Colombari, Eduardo; Dias, Maria Celeste; Afonso, José A.; Carmo, João Paulo Pereira doOptogenetics leverages light to control neural circuits, but traditional systems are often bulky and tethered, limiting their use. This work introduces OptoBrain, a novel, portable wireless system for optogenetics designed to overcome these challenges. The system integrates modules for multichannel data acquisition, smart neurostimulation, and continuous processing, with a focus on low-power and low-voltage ope...
GOOD - Agroecología para las malas hierbas: construyendo una red de manejo agro...
Osuna, Maria D.; Ramos, María; Santiago, Ana de; Maya, Valentín; Baptista, Jorge; Groenewegen, Micha; Oliveira, Rui S.; Sousa, José P.Las hierbas adventicias afectan negativamente a la sostenibilidad de los sistemas agrícolas de la Unión Europea (UE), cuya gestión depende en gran medida de los herbicidas. La estrategia "de la granja a la mesa" de la UE tiene como objetivo promover la agroecología y la transición hacia sistemas agrícolas sostenibles y resilientes, incluyendo la reducción del uso de herbicidas. GOOD es un proyecto de 4 años de ...
Metabolomics as a Tool to Understand Nano-Plant Interactions: The Case Study of...
Silva, Sónia; Dias, Maria Celeste; Pinto, Diana C. G. A.; Silva, Artur M. S.Metabolomics is a powerful tool in diverse research areas, enabling an understanding of the response of organisms, such as plants, to external factors, their resistance and tolerance mechanisms against stressors, the biochemical changes and signals during plant development, and the role of specialized metabolites. Despite its advantages, metabolomics is still underused in areas such as nano-plant interactions. ...
Functional Groups Response to Water Deficit in Mediterranean Ecosystems
Castro, Helena; Dias, Maria Celeste; Sousa, José Paulo; Freitas, HelenaEnhanced drought, more frequent rainfall events and increased inter-annual variability of precipitation are the main trends of climate expected for the Mediterranean. Drought is one of the most important stressors for plants and significantly impacts plant communities causing changes in plant composition and species dominance. Through an experiment under controlled conditions, we assessed the response of Medite...
Impact of genome duplications in drought tolerance and distribution of the dipl...
Castro, Helena; Dias, Maria Celeste; Castro, Mariana; Loureiro, João; Castro, SilviaPolyploidy has important ecological effects, including ploidy-mediated effects on morphology, breeding system and ecological tolerances. However, there is still little comprehensive research available to test its adaptive significance and its role in driving distributional patterns. This work aimed to assess the contribution of genome duplications to ecological divergence using an experimental approach with the...
Low Doses of Anatase and Rutile Nanoparticles Differently Modulate Photosynthes...
Mariz-Ponte, Nuno; Sario, Sara; Mendes, Rafael J.; Couto, Márcio; Gimranov, Emil; Santos, Marino; Correia, Cristiana V.; Gomes, AniciaIndustrial applications of titanium dioxide nanoparticles (TiO2 NPs) are wide, and their use in nano-fertilizing technology has been proposed in the last few years. Bioactivity evaluation of different TiO2 NPs formulations is therefore crucial, not only to select the most appropriate formulation but also to validate potential agro-applications. In the current work, we compared the bioactivity of the two most us...
Chemical Profiling of Two Italian Olea europaea (L.) Varieties Subjected to UV-...
Piccini, Chiara; Cantini, Claudio; Cai, Giampiero; Pinto, Diana C G A; Silva, Artur M. S.; Romi, Marco; Dias, Maria CelesteThe depletion of the stratospheric ozone layer due to natural and/or anthropogenic causes decreases the amount of UV-B radiation filtered, and consequently increases the risk of potential damage to organisms. In the Mediterranean region, high UV-B indices are frequent. Even for species typical of this region, such as the olive tree, the progressive increase in UV-B radiation represents a threat. This work aimed...
Quercus suber Roots Activate Antioxidant and Membrane Protective Processes in R...
Dias, Maria Celeste; Santos, Conceição; Araújo, Márcia; Barros, Pedro M.; Oliveira, Margarida; Oliveira, José Miguel P. Ferreira deCork oak (Quercus suber) is a species native to Mediterranean areas and its adaptation to the increasingly prevalent abiotic stresses, such as soil salinization, remain unknown. In sequence with recent studies on salt stress response in the leaf, it is fundamental to uncover the plasticity of roots directly exposed to high salinity to better understand how Q. suber copes with salt stress. In the present study w...
Titanium and Zinc Based Nanomaterials in Agriculture: A Promising Approach to D...
Silva, Sónia; Dias, Maria Celeste; Silva, Artur M. S.Abiotic stresses, such as those induced by climatic factors or contaminants, and biotic stresses prompted by phytopathogens and pests inflict tremendous losses in agriculture and are major threats to worldwide food security. In addition, climate changes will exacerbate these factors as well as their negative impact on crops. Drought, salinity, heavy metals, pesticides, and drugs are major environmental problems...
Olive Varieties under UV-B Stress Show Distinct Responses in Terms of Antioxida...
Piccini, Chiara; Cai, Giampiero; Dias, Maria Celeste; Araújo, Márcia; Parri, Sara; Romi, Marco; Faleri, Claudia; Cantini, ClaudioIn recent decades, atmospheric pollution led to a progressive reduction of the ozone layer with a consequent increase in UV-B radiation. Despite the high adaptation of olive trees to the Mediterranean environment, the progressive increase of UV-B radiation is a risk factor for olive tree cultivation. It is therefore necessary to understand how high levels of UV-B radiation affect olive plants and to identify ol...
