Transcriptomic Analyses Reveal That Coffea arabica and Coffea canephora Have Mo...
Marques, Isabel; Fernandes, Isabel; Paulo, Octávio S.; Rodrigues, Ana P.; Partelli, Fábio L.; DaMatta, Fábio M.; Ribeiro-Barros, Ana I.Increasing exposure to unfavorable temperatures and water deficit imposes major con- straints on most crops worldwide. Despite several studies regarding coffee responses to abiotic stresses, transcriptome modulation due to simultaneous stresses remains poorly understood. This study unravels transcriptomic responses under the combined action of drought and temperature in leaves from the two most traded species: ...

Marques, Isabel; Fernandes, Isabel; Paulo, Octávio S.; Batista, Dora; Lidon, Fernando C.; Rodrigues, Ana P.; Partelli, Fábio L.; DaMatta, Fábio M.Increasing exposure to unfavorable temperatures and water deficit imposes major constraints on most crops worldwide. Despite several studies regarding coffee responses to abiotic stresses, transcriptome modulation due to simultaneous stresses remains poorly understood. This study unravels transcriptomic responses under the combined action of drought and temperature in leaves from the two most traded species: Co...
The ADnet Bayesian belief network for alder decline: Integrating empirical data...
Gomes Marques, Inês; Vieites-Blanco, Cristina; Rodríguez-González, Patricia M.; Segurado, Pedro; Marques, Marlene; Barrento, Maria J.The globalization in plant material trading has caused the emergence of invasive pests in many ecosystems, such as the alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, effective and accessible decision tools are required to help managers and stakeholders control t...
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...
Intrinsic non-stomatal resilience to drought of the photosynthetic apparatus in...
JN; Rodrigues, Ana P.; Lidon, Fernando C.; P. Pais, Isabel; Marques, Isabel; Gouveia, Duarte; ARMENGAUD, Jean; Silva, Maria J.; Martins, SóniaGrowing water restrictions associated with climate changes constitute daunting challenges to crop performance. This study unveils the impacts of moderate (MWD) or severe (SWD) water deficit, and their interaction with air [CO2], on the photosynthetic apparatus of Coffea canephora Pierre ex A. Froehner cv. Conilon Clone 153 (CL153) and Coffea arabica L. cv. Icatu. Seven year-old potted plants grown under 380 (aC...
Implications of nighttime temperature on metamitron impacts on the photosynthet...
Rosa, Nídia; Lidon, Fernando C.; Rodrigues, Ana P.; Pais, Isabel P.; Scotti-Campos, Paula; Asín, Luís; Oliveira, Cristina M.; Ramalho, José C.Metamitron (MET) is a fruitlet thinning compound for apple trees, needing better understanding of its action on leaf energy metabolism, depending on nighttime temperature. A trial under environmental controlled conditions was set with ‘Golden Reinders’ potted trees, under 25/7.5 and 25/15 ◦C (diurnal/nighttime temperature), with (MET, 247.5 ppm) or without (CTR) application, and considering the monitoring of ph...
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...
Can foliar pulverization with CaCl2 and Ca(NO3)2 trigger Ca enrichment in Solan...
Coelho, Ana Rita F.; Lidon, Fernando C.; Pessoa, Cláudia Campos; Marques, Ana Coelho; Luís, Inês Carmo; Caleiro, João; Simões, Manuela; Kullberg, JoséThis study aimed to assess the efficiency of Ca enrichment in tubers of three genotypes of Solanum tuberosum L., through foliar spraying with CaCl2 and Ca(NO3)2 solutions. In this context, soil heterogeneity of three potato-growing fields, as well as the implications of Ca accumulation among tissues and some quality parameters were assessed. Three potato varieties (Agria, Picasso and Rossi) were grown in three ...
Resilient and sensitive key points of the photosynthetic machinery of coffea sp...
Dubberstein, Danielly; Lidon, Fernando C.; Rodrigues, Ana P.; Semedo, José N.; Marques, Isabel; Rodrigues, Weverton P.; Gouveia, Duarte; ARMENGAUD, JeanThis study unveils the single and combined drought and heat impacts on the photosynthetic performance ofCoffea arabicacv. Icatu andC. canephoracv. Conilon Clone 153 (CL153). Well-watered (WW) potted plants were gradually submitted to severe water deficit (SWD) along 20 days under adequate temperature (25/20 degrees C, day/night), and thereafter exposed to a gradual temperature rise up to 42/30 degrees C, follow...
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...
