Next-generation proteomics reveals a greater antioxidative response to drought ...
Marques, Isabel; Gouveia, Duarte; Gaillard, Jean-Charles; Martins, Sónia; Semedo, Magda C.; Lidon, Fernando C.; DaMatta, Fabio; Ribeiro, AnaDrought is a major threat to coffee, compromising the quality and quantity of its production. We have analyzed the core proteome of 18 Coffea canephora cv. Conilon Clone 153 and C. arabica cv. Icatu plants and assessed their responses to moderate (MWD) and severe (SWD) water deficits. Label-free quantitative shotgun proteomics identified 3000 proteins in both genotypes, but less than 0.8% contributed to ca. 20%...
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...
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...
Impaired malate and fumarate accumulation due the mutation of tonoplast dicarbo...
Medeiros, David B.; Barros, Kallyne; Barros, Jessica AS; Omena-Garcia, Rebeca P; Detmann, Kelly C; Silva, Willian Batista; DaMatta, FabioMalate is a central metabolite involved in a multiplicity of plant metabolic pathways, being associated with mitochondrial metabolism and playing significant roles n stomatal movements. Vacuolar malate transport has been characterized at the molecular level and is performed by at least one carrier protein and two channels in Arabidopsis vacuoles. The absence of the Arabidopsis thaliana tonoplast Dicarboxylate T...
