Solute transport across plant cell membranes
Conde, Artur; Martins, Viviana Maria Varajão; Noronha, Henrique Luís Silva; 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. ...
Membrane transport, sensing and signaling in plant adaptation to environmental ...
Conde, Artur; Chaves, M. Manuela; Gerós, H.Plants are generally well adapted to a wide range of environmental conditions. Even though they have notably prospered in our planet, stressful conditions such as salinity, drought and cold or heat, which are increasingly being observed worldwide in the context of the ongoing climate changes, limit their growth and productivity. Behind the remarkable ability of plants to cope with these stresses and still thriv...
Mannitol transport and mannitol dehydrogenase activities are coordinated in ole...
Conde, Artur; Silva, Paulo; Agasse, A.; Conde, Carlos; Gerós, H.This is a pre-copy-editing, author-produced PDF of an article accepted for publication in Plant and Cell Physiology following peer review. The definitive publisher-authenticated version is available online at http://pcp.oxfordjournals.org/cgi/content/abstract/pcr121? ijkey=6orgUM5fkIjedYn&keytype=ref; The intracellular accumulation of organic compatible solutes functioning as osmoprotectants, such as polyols, i...
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 ...
Vacuole-mitochondrial cross-talk during apoptosis in yeast: a model for underst...
Sousa, Maria João; Azevedo, F.; Pedras, Andreia; Marques, Carolina; Coutinho, O. P.; Preto, Ana; Gerós, H.; Chaves, S. R.; Côrte-Real, ManuelaThe yeast apoptosis field emerged with the finding that key components of the apoptotic machinery are conserved in these simple eukaryotes. Thus it became possible to exploit these genetically tractable organisms to improve our understanding of the intricate mechanisms of cell death in higher eukaryotes and of severe human diseases associated with apoptosis dysfunctions. Early on, it was recognized that a mitoc...
Mannitol transport and oxidation are synchronized in Olea europaea under salt a...
Conde, Artur; Silva, Paulo; Agasse, A.; Conde, Carlos; Gerós, H.The intracellular accumulation of organic compatible solutes acting as osmoprotectants, such as polyols, is an essential response mechanism of several plants to drought and salinity. In Olea europaea a mannitol transport system (OeMaT1) has been previously characterised as a key player in plant response to salinity, and here, heterotrophic sink models, such as olive suspension-cultured cells and fruit tissues, ...
Berry phenolics of grapevine under challenging environments
Teixeira, António; Eiras-Dias, José; Castellarin, Simone D.; Gerós, H.Plant phenolics have been for many years a theme of major scientific and applied interest. Grape berry phenolics contribute to organoleptic properties, color and protection against environmental challenges. Climate change has already caused significant warming in most grape-growing areas of the world, and the climatic conditions determine, to a large degree, the grape varieties that can be cultivated as well as...
The first insight into the metabolite profiling of grapes from three vitis vini...
Teixeira, António; Martins, Viviana; Noronha, Henrique Luís Silva; Eiras-Dias, José; Gerós, H.The characterization of the metabolites accumulated in the grapes of specific cultivars grown in different climates is of particular importance for viticulturists and enologists. In the present study, the metabolite profiling of grapes from the cultivars, Alvarinho, Arinto and Padeiro de Basto, of two Portuguese Controlled Denomination of Origin (DOC) regions (Vinho Verde and Lisboa) was investigated by gas chr...
Copper impacts in grapevine (Vitis vinifera L.): molecular, biochemical and bio...
Martins, Viviana Maria VarajãoTese de doutoramento em Programa Doutoral em Biologia de Plantas; Since the development of Bordeaux mixture in the late 1800’s, copper-based fungicides have been widely used against grapevine (Vitis vinifera L.) diseases, mainly in organic but also in conventional viticulture. Although they initially seemed to improve plant growth in unproductive lands, their intensive use has raised concerns regarding toxicity...
Changes in the volatile composition of wine from grapes treated with Bordeaux m...
Martins, V.; Teixeira, A.; Gerós, H.Background and Aims: We investigated the effect of the application of Bordeaux mixture in the vineyard on the copper concentration in the must, and the consequences for the volatile composition of wine.Methods and Results: Musts from grapes cv. Vinhao treated with Bordeaux mixture or with a triazole-based fungicide were prepared at a laboratory scale. Copper concentration decreased from 31.4 to 12.6 mg/L during...
