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: ...

Overexpression of Water-Responsive Genes Promoted by Elevated CO2 Reduces ROS a...
Marques, Isabel; Fernandes, Isabel; Paulo, Octávio S.; Batista, Dora; Lidon, Fernando C.; Partelli, Fábio; DaMatta, Fábio M.; Ribeiro-Barros, Ana I.Drought is a major constraint to plant growth and productivity worldwide and will aggravate as water availability becomes scarcer. Although elevated air [CO2] might mitigate some of these effects in plants, the mechanisms underlying the involved responses are poorly understood in woody economically important crops such as Coffea. This study analyzed transcriptome changes in Coffea canephora cv. CL153 and C. ara...
Genomic evaluation of Coffea arabica and its wild relative Coffea racemosa in M...
Tapaça, Inocência da Piedade Ernesto; Mavuque, Lopes; Corti, Riccardo; Pedrazzani, Samuele; Maquia, Ivete S. A.; Tongai, Castigo; Partelli, Fábio LuizClimate change is negatively affecting the coffee value chain, with a direct effect on approximately 100 million people from 80 countries. This has been attributed to the high vulnerability of the two-mainstream species, Coffea arabica and Coffea canephora, to extreme weather events, with notable uneven increases in market prices. Taking into account the narrow genetic plasticity of the commercial coffee cultiv...
Diversity in Coffea arabica cultivars in the mountains of Gorongosa National Pa...
Alberto, Niquisse J.; Ramalho, José C.; Ribeiro-Barros, Ana I.; Viana, Alexandre P.; Krohling, Cesar A.; Moiane, Sional S.; Alberto, ZitoGenetic characteristics and their interaction with environmental conditions, including nutritional management, determine coffee productivity and quality. The objective of this study was to evaluate fruit traits and nutrient accumulation in the fruit, husk, and bean, as well as in the leaves of different Coffea arabica cultivars cropped in the Gorongosa National Park, Mozambique. The experiment evaluated nine co...

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...
Salt Stress Tolerance in Casuarina glauca: Insights from the Branchlets Transcr...
Fernandes, Isabel; Paulo, Octávio S.; Marques, Isabel; Sarjkar, Indrani; Sen, Arnab; Graça, Inês; Pawlowski, Katharina; Ramalho, José C.Climate change and the accelerated rate of population growth are imposing a progressive degradation of natural ecosystems worldwide. In this context, the use of pioneer trees represents a powerful approach to reverse the situation. Among others, N2-fixing actinorhizal trees constitute important elements of plant communities and have been successfully used in land reclamation at a global scale. In this study, we...
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...
