Solute transport across plant cell membranes
Conde, Artur; Martins, Viviana; Noronha, Henrique; Conde, Carlos Alberto da Silva; Fontes, N.; Gerós, H.CanaBQ is a Journal of the Portuguese Biochemical Society (http://canalbq.spb.pt/index.html) ; The transport of solutes across cell membranes, including organic nutrients, such as sugar, osmolytes, ions or metabolic waste products, is of extreme importance in all living systems. Up to 14% of the genome of all organisms represents information for transport proteins, which reflects the importance of such process...
Grape berry vacuole : a complex and heterogeneous membrane system specialized i...
Fontes, N.; Gerós, H.; Delrot, SergeVacuoles fulfill highly specialized functions depending on cell type and tissue and plant developmental stage. This complex and dynamic organelle is the main reservoir of grape berry cells, playing a major role during fruit development and ripening. Berry development is accompanied by modifications in size, composition, color, texture, flavor, and pathogen susceptibility, primarily because of changes in vacuola...
New observations on the integrity, structure and physiology of flesh cells from...
Fontes, N.; Côrte-Real, Manuela; Gerós, H.The physiological/structural status of the soft ripened berry is still a matter of debate. In this paper isolated mesocarp cells from ripened berries of both wine and table varieties were studied by bright-field, fluorescence and confocal microscopy and flow cytometry to highlight the organization of berry flesh cell, function and viability. Flow cytometry analysis confirmed that protoplasting from grape berry ...
Biochemical changes throughout grape berry development and fruit and wine quality
Conde, C.; Silva, Paulo; Fontes, N.; Dias, Alberto Carlos Pires; Tavares, R. M.; Sousa, Maria João; Agasse, A.; Delrot, Serge; Gerós, H.Wine is made up of more than one thousand compounds, the majority of which, such as vitamins and minerals, come from the grapes, while others, like ethanol and glycerol, are products of the winemaking process. Although sugars are either partially or completely transformed, sugar import and accumulation into the ripening berry is a major parameter of wine quality. Sugar status is directly related to the final al...
