Biochemical Changes throughout Grape Berry Development and Fruit and Wine Quality
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
Regulation by salt of vacuolar H+-ATPase and H+-pyrophosphatase activities and Na+/H+ exchange
TLDR
This review focuses on the transcriptional and post-transcriptional regulation by salt of tonoplast proton pumps and Na+/H+ exchangers and on the signalling pathways involved in salt sensing.
Membrane transport, sensing and signaling in plant adaptation to environmental stress.
TLDR
The full understanding of the plant cell complex defense mechanisms under stress may allow for the engineering of more tolerant plants or the optimization of cultivation practices to improve yield and productivity, which is crucial at the present time as food resources are progressively scarce.
Polyols in grape berry: transport and metabolic adjustments as a physiological strategy for water-deficit stress tolerance in grapevine.
TLDR
The impact of polyols on grape berry composition and plant response to water deficit stress, via modifications in polyol transport and metabolism, was analysed by integrating metabolomics with transcriptional analysis and biochemical approaches.
Pathways of Glucose Regulation of Monosaccharide Transport in Grape Cells1
TLDR
Present data provide an example showing control of plant sugar transporters by their own substrate both at transcriptional and posttranscriptional levels, consistent with the regulating role of Glc on VvHT1 expression found in suspension-cultured cells.
Berry Phenolics of Grapevine under Challenging Environments
TLDR
The full understanding of how and when specific phenolic compounds accumulate in the berry, and how the varietal grape berry metabolism responds to the environment is of utmost importance to adjust agricultural practices and thus, modify wine profile.
Copper transport and compartmentation in grape cells.
TLDR
Physiological, biochemical and molecular approaches were combined to investigate the impacts of copper in grape cells and how it is transported and compartmented intracellularly and showed that VvCTr1 and VvTr8 were distinctly affected by CuSO(4) availability in grape cell cultures and that both genes were highly expressed in the green stage of grape berries.
Activity of tonoplast proton pumps and Na+/H+ exchange in potato cell cultures is modulated by salt.
TLDR
The increase of both the pH gradient across the tonoplast and the Na(+)/H(+) antiport activity in response to salt strongly suggests that Na(+) sequestration into the vacuole contributes to salt tolerance in potato.
