Protective Responses at the Biochemical and Molecular Level Differ between a Co...
Vinci, Gabriella; Marques, Isabel; Rodrigues, Ana P.; Martins, Sónia; Leitão, António E.; Semedo, Magda C.; Silva, Maria J.; Lidon, Fernando C.Climate changes with global warming associated with rising atmospheric [CO2] can strongly impact crop performance, including coffee, which is one of the most world’s traded agricultural commodities. Therefore, it is of utmost importance to understand the mechanisms of heat tolerance and the potential role of elevated air CO2 (eCO2) in the coffee plant response, particularly regarding the antioxidant and other p...
Zinc Biofortification in Vitis vinifera: Implications for Quality and Wine Prod...
Daccak, Diana; Lidon, Fernando C.; Luís, Inês Carmo; Marques, Ana Coelho; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Caleiro, João; Ramalho, José C.Nowadays, there is a growing concern about micronutrient deficits in food products, with agronomic biofortification being considered a mitigation strategy. In this context, as Zn is essential for growth and maintenance of human health, a workflow for the biofortification of grapes from the Vitis vinifera variety Fernão Pires, which contains this nutrient, was carried out considering the soil properties of the v...
Shade and Altitude Implications on the Physical and Chemical Attributes of Gree...
Cassamo, Crimildo T.; Mangueze, Adilson V.J.; Leitão, António E.; Pais, Isabel P.; Moreira, Rita; Campa, Claudine; Chiulele, Rogério; Reis, Fabricio O.Coffea arabica L. is as a tropical crop that can be grown under monocrop or agroforestry (AFS) systems, usually at altitudes greater than 600 m, with suitable environmental conditions to bean quality. This study aimed to assess the effect of altitude (650, 825, and 935 m) and light conditions (deep shade—DS, and moderate shade—MS provided by native trees, and full Sun—FS) on the physical and chemical attributes...
Will Casuarina glauca Stress Resilience Be Maintained in the Face of Climate Ch...
Jorge, Tiago F.; Ramalho, José C.; Alseekh, Saleh; Pais, Isabel P.; Leitão, António E.; Rodrigues, Ana P.; Scotti-Campos, Paula; Ribeiro-Barros, Ana I.Actinorhizal plants have been regarded as promising species in the current climate change context due to their high tolerance to a multitude of abiotic stresses. While combined salt-heat stress effects have been studied in crop species, their impact on the model actinorhizal plant, Casuarina glauca, has not yet been fully addressed. The effect of single salt (400 mM NaCl) and heat (control at 26/22 C, supra opt...
Drought response of cowpea (Vigna unguiculata (L.) Walp.) landraces at leaf phy...
Gomes, Ana M.F.; Rodrigues, Ana P.; António, Carla; Rodrigues, Ana M.; Leitão, António E.; Batista-Santos, Paula; Nhantumbo, NascimentoDrought threatens the world’s food production, particularly in Sub Saharan Africa low external input and rain fed agricultural systems, where cowpea (Vigna unguiculata (L.) Walp.) is an important food crop. In the context of growing concerns regarding climate changes implications on water availability, this study aimed at 1) to evaluate the drought responses in cowpea landraces with contrasting drought toleranc...
Can elevated air [CO 2] conditions mitigate the predicted warming impact on the...
DaMatta, Fábio M.; Ramalho, José C.; Pais, Isabel P.; Leitão, António E.; Guerra, Mauro; Reboredo, Fernando H.; Máguas, Cristina M.; Carvalho, Maria L.Climate changes, mostly related to high temperature, are predicted to have major negative impacts on coffee crop yield and bean quality. Recent studies revealed that elevated air [CO2] mitigates the impact of heat on leaf physiology. However, the extent of the interaction between elevated air [CO2] and heat on coffee bean quality was never addressed. In this study, the single and combined impacts of enhanced [C...

Mitigation of the negative impact of warming on the coffee crop: the role of in...
Dubberstein, Danielly; Rodrigues, Weverton P.; Semedo, José N.; Rodrigues, Ana P.; Pais, Isabel P.; Leitão, António E.; Partelli, Fábio L.Crop sustainability can be threatened by new environmental challenges regarding predicted climate changes and global warming. Therefore, the study of real biological impacts of future environmental conditions (e.g., increased air [CO2], supra-optimal temperature and water scarcity) on crop plants, as well as the re-evaluation of management procedures and strategies, must be undertaken in order to improve crop a...

Protective response mechanisms to heat stress in interaction with high [CO2] co...
Martins, Madlles Q.; Rodrigues, Weverton P.; Fortunato, Ana S.; Leitão, António E.; Rodrigues, Ana P.; Pais, Isabel P.; Martins, Lima D.Modeling studies have predicted that coffee crop will be endangered by future global warming, but recent reports highlighted that high [CO 2 ] can mitigate heat impacts on coffee. This work aimed at identifying heat protective mechanisms promoted by CO 2 in Coffea arabica (cv. Icatu and IPR108) and Coffea canephora cv. Conilon CL153. Plants were grown at 25/20 ◦ C (day/night), under 380 or 700 μL CO 2 L − 1 , a...
