MetabolomicsA Metabolome Atlas of Grape Biodiversity
Grapevine (Vitis spp.) is one of the world’s most economically, culturally, and biologically important fruit crops, with remarkable diversity spanning thousands of V. vinifera cultivars together with rootstocks and wild relatives. Yet grapevine biodiversity has never been systematically explored at ...

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...

MetabolomicsThe accumulation profiles of terpene metabolites in three Muscat table grape cultivars through HS-SPME-GCMS
Aroma is an important parameter for table grapes and wines; terpenes are typical compounds in Muscat-type grape cultivars and can be easily perceived by humans because of their low olfactory threshold. Volatile terpenes contribute directly to the aroma character, while glycoside-bound terpenes are p...

MetabolomicsThe measurement of spatial distribution of grape metabolites in berry tissues using LC-MS
The study aims to describe the differential spatial distrubution of secondary metabolites in different grape species,. The aims is to describe the characteristics that differentiate wild grapes from good quality vinifera grapes, understand the limits and advantages from both classes.

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...

MetabolomicsUntargeted lipidomic profiling of grape highlights the importance of modified lipid species beyond the traditional compound classes

The aim of this paper is to provide a detailed characterisation of grape lipidome. To achieve this objective, it starts by describing a pipeline implemented in R software to allow the semi-automatic annotation of the detected lipid species. It also provides an extensive description of the differe...

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...

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 (Volatile organic compounds; SPME-GC-MS 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...
