MetabolomicsThe plasticity of the grapevine berry transcriptome
Vitis vinifera cultivar Corvina clone 48 berries were harvested from different vineyards, each located in one of the three most important wine production macro-areas of the Verona region: Bardolino, Valpolicella and Soave, on the basis of the site geographical coordinates. For each of the selected v...

TranscriptomicsTranscriptional analysis of late ripening stages of grapevine berry
Background: The composition of grapevine berry at harvest is a major determinant of wine quality. Optimal oenological maturity of berries is characterized by a high sugar/acidity ratio, high anthocyanin content in the skin, and low astringency. However, harvest time is still mostly determined empiri...

MetabolomicsHaplotype-specific expression of a terpene synthase underlies linalool variation in the grapevine cultivar Riesling
Grapevine cultivars vary widely in monoterpenoid content, yet the genetic and regulatory mechanisms underlying this variation remain poorly characterized beyond highly aromatic Muscat types. We profiled free volatiles and monoterpenoid glycosides in a Riesling × Cabernet Sauvignon F1 mapping populat...

MetabolomicsA high-resolution Orbitrap mass spectral library for trace volatile compounds in fruit wines
The overall aroma is an important factor of the sensory quality of fruit wines, which attributed to hundreds of volatile compounds. However, the qualitative determination of trace volatile compounds is considered to be very challenging work. GC-Orbitrap-MS with high resolution and high sensitivity p...

TranscriptomicsIncreasing the source/sink ratio in Vitis vinifera (cv Sangiovese) induces extensive transcriptome reprogramming and modifies berry ripening
Background: Cluster thinning is an agronomic practice in which a proportion of berry clusters are removed from the vine to increase the source/sink ratio and improve the quality of the remaining berries. Until now no transcriptomic data have been reported describing the mechanisms that underlie the ...

TranscriptomicsThe grapevine expression atlas reveals a deep transcriptome shift driving the entire plant into a maturation program
The first genome-wide transcriptomic atlas of grapevine (Vitis vinifera) is based on 54 diverse samples expressing ~93% of predicted grapevine genes. Pollen and senescent leaves have unique transcriptomes but microarray analysis grouped all other samples into vegetative/green or mature/woody categor...

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 ...

TranscriptomicsSelective defoliation affects plant growth, fruit transcriptional ripening program and flavonoid metabolism in grapevine.
The purpose of this study was to quantify the effects of basal leaf removal applied in Sangiovese cultivar at two different phonological stages, pre-bloom and veraison, on berry composition. As very few papers were published about the regulation of gene expression induced by vineyard management tech...

TranscriptomicsThe plasticity of the grapevine berry transcriptome
Background: Phenotypic plasticity refers to the range of phenotypes a single genotype can express as a function of its environment. These phenotypic variations are attributable to the effect of the environment on the expression and function of genes influencing plastic traits. We investigated phenot...

MetabolomicsTwo apples a day modulate human:microbiome co-metabolic processing of polyphenols, tyrosine and tryptophan

PURPOSE: Validated biomarkers of food intake (BFIs) have recently been suggested as a useful tool to assess adherence to dietary guidelines or compliance in human dietary interventions. Although many new candidate biomarkers have emerged in the last decades for different foods fr...
