Economic and Financial Evaluation of Cork Oaks Forest Plantations Under Fertirr...
Camilo-Alves, Constança; Nunes, José António; Poeiras, Ana; Ribeiro, João; Vaz, Margarida; Mota Barroso, João; Almeida-Ribeiro, NunoCork oaks usually become productive after 20 years of age. To shorten this period, fertirrigation has been tested to enhance tree vitality and growth, thus anticipating cork stripping. This study aims to determine the economic and financial indicators of this afforestation technique compared to rainfed indicators. Simulations were conducted based on information gathered from fertirrigated and rainfed stands, as...
Efficient regulation of CO2 assimilation enables greater resilience to high tem...
Correira, Pedro; Bernardes da Silva, Anabela; Vaz, Margarida; Carmo-Silva, Elizabete; Jorge, Marques da SilvaIncreasing temperatures and extended drought episodes are among the major constraints affecting food production. Maize has a relatively high temperature optimum for photosynthesis compared to C3 crops, however, the response of this important C4 crop to the combination of heat and drought stress is poorly understood. Here, we hypothesized that resilience to high temperature combined with water deficit (WD) would...
Water as a critical issue for viticulture in southern Europe: sustainability vs...
Costa, Joaquim Miguel; Vaz, Margarida; Escalona, J.M.; Egipto, Ricardo; Lopes, Carlos Manuel; Medrano, H; Chaves, Maria ManuelaWater is a vulnerable resource in the Mediterranean region, but irrigation demands have been increasing to mitigate effects of environmental stress. Sustainable wine production involves the precise use of water in the vineyard and winery. Improved knowledge on grapevine ecophysiology and genetics, the use of sensors for soil and canopy monitoring, plant phenotyping and improved crop management can help save wat...
Arbuscular Mycorrhiza Extraradical Mycelium Promotes Si and Mn Subcellular Redi...
Faria, Jorge M.S.; Conceição, Taiana A; Teixeira, Dora Martins; Brito, Isabel; Barrulas, Pedro; Pinto, Ana Paula; Vaz, Margarida; Carvalho, MárioAbstract: Manganese (Mn) and aluminum (Al) toxicities are serious edaphic limitations to crop production in acidic soils. Excess Mn can be countered using a stress-adapted soil microbiota that establish symbiotic relationships with native plants. The arbuscular mycorrhizal fungi (AMF) associated with Lolium rigidum L. develop extraradical mycelia (ERM) that quickly colonize wheat and lead to greater shoot growt...
Influence of water and nutrients on cork oak radial growth – looking for an eff...
Constança, Camilo-Alves; José Antonio, Nunes ; Ana Patricia, Poeiras; João, Ribeiro ; Dinis, Cati; M. Barroso , João; Vaz, MargaridaAbstract The widespread cork oak (Quercus suber L.) mortality and reduced afforestation /regeneration are causing an overall reduction in cork production. To enhance trees’ growth and vitality, afforestation techniques using fertirrigation were tested. The main objective was the promotion of trees’ growth on new dense plantations using minimum water requirements until reaching productive forests. The experiment...
The use of gene-specific classification guidelines VS ACMG 2015: MODY case study
Dario, Paulo; Vaz, Margarida; Gaspar, Gisela; Bourbon, MafaldaMaturity Onset Diabetes of the Young (MODY) is a form of diabetes characterized as a dominant monogenic disorder. It is caused by pathogenic or likely pathogenic variants in any of the 14 genes currently associated with the disease. Since 2015 our laboratory has employed the classification algorithm guidelines established by the American College of Medical Genetics and Genomics and the Association for Molecular...
Avaliação de diferenças bioquímicas entre indivíduos diabéticos com e sem varia...
Vaz, Margarida; Gaspar, Gisela; Agapito, Ana; Neves, Ana Carolina; Bogalho, Ana Paula; Almeida, Bruno; Pereira, Carla; Fonseca, FernandoA diabetes tipo MODY (Maturity-onset diabetes of the young) é um tipo de diabetes causada por mutações em um único gene. Existe 14 genes associados a essa doença, no entanto, a maioria dos casos de MODY é causada por alterações nos genes GCK, HNF1A, HNF1B e HNF4A. Cada subtipo desta patologia apresenta características fenotípicas, metabólicas e complicações para a saúde distintas o que exige uma adequação terap...
