MetabolomicsInvestigation of Brazilian grape juice metabolomic profile changes caused by methyl jasmonate pre-harvest treatment

Grape juice is a major source of potential health-promoting bioactive polyphenols, especially for children and those who do not consume wine. Since the subtropical climate may negatively affect the concentrations of grape polyphenols, especially anthocyanins, elicitors such as methyl jasmonate (M...

MetabolomicsCoupling between high-resolution mass spectrometry and focalized data-analysis methods provides the identification of new putative glycosidic non-anthocyanic flavonoids in grape

INTRODUCTION: The biochemical diversity of flavonoids is based on glycosylation, methylation, acylation, and many other modifications of the flavonoid backbone. Liquid chromatography coupled to high-resolution mass spectrometry demonstrated to be a powerful approach to gain new i...

MetabolomicsFrom grape berries to wines: drought impacts on key secondary metabolites

AIM: We aimed to study the impact of water deficit on the concentration of key flavour and phenolic secondary metabolites of wines.

METHODS AND RESULTS: A drought-stress field trial was conducted on Vitis vinifera cv. Merlot and Tocai Friulano for two seaso...

ProteomicsDifferential protein expression in berry skin from red grapes with varying hybrid character
Protein expression from berry skin of four different red grape biotypes was compared at a proteome-wide level by bottom-up shotgun proteomics, label free quantification and MaxQuant-assisted computational analysis. Red grapes were from a purebred Vitis vinifera (Aglianico cv.), a V. vinifera (local ...

MetabolomicsMulti-Omics and Integrated Network Analyses Reveal New Insights into the Systems Relationships between Metabolites, Structural Genes, and Transcriptional Regulators in Developing Grape Berries (Vitis vinifera L.) Exposed to Water Deficit (Carotenoids; UPLC-DAD assay)

Grapes are one of the major fruit crops and they are cultivated in many dry environments. This study comprehensively characterizes the metabolic response of grape berries exposed to water deficit at different developmental stages. Increases of proline, branched-chain amino acids, phenylpropanoids...

MetabolomicsThe influence of storage on the “chemical age” of red wines
Storage conditions and duration have a considerable influence on wine quality. Optimum temperature and humidity conditions may improve wine quality through ageing, while incorrect or excessively long storage leads to negative results. In order to evaluate the global effects of storage on red wine co...
