(Submitter supplied) Vitis vinifera berries are sensitive towards infection by the necrothopic pathogen Botrytis cinerea leading to important economic losses worldwide. The combined analysis of the transcriptome and metabolome associated with the infection has not been previously performed in grapes or in another fleshy fruit. In an attempt to identify the molecular and metabolic mechanisms associated with the infection, pepper- corn size fruits (EL 29) were infected in-field and green berries (EL 33) and veraison berries (EL 35) were collected for microarray analysis complemented with metabolic profiling using GC-EI-TOF/MS and headspace GC-EI-MS platforms. more...

(Submitter supplied) Noble rot results from atypical infections of ripe grape berries by Botrytis cinerea. Unlike bunch rot, noble rot promotes favorable changes in grape berries and accumulation of secondary metabolites that enhance wine grape quality. Noble rot-infected berries of Sémillon, a white-skinned variety, were collected over three years from a commercial vineyard at the same time fruit were harvested for botrytized wine production. more...

(Submitter supplied) Background Grapes (Vitis vinifera L.) are economically the most important fruit crop worldwide. However, the complexity of molecular and biochemical events that lead to the onset of ripening of nonclimacteric fruits is not fully understood which is further complicated in grapes due to seasonal and cultivar specific variantion. The Portuguese wine variety Trincadeira gives rise to high quality wines but presents extremely irregular berry ripening among seasons probably due to high susceptibility to abiotic and biotic stresses. more...

(Submitter supplied) At the onset of ripening (veraison), Vitis vinifera L. cv Muscat Hamburg fruiting cuttings were exposed to four different environmental regimes in two growth chambers set up: 20/15ºC (day/night) and 30/25ºC (day/night) and with two different photosynthetic photon flux density (PPFD) conditions (200 and 400 μmol•m−2•s−1 PPFD) at grape bunch level during a 14 h photoperiod. Fruiting cuttings were selected to have similar grape bunch size avoiding changes in berry quality. more...

(Submitter supplied) The abscisic acid (ABA) increase and auxin decline are both indicators of ripening initiation in grape berry, and norisoprenoid accumulation also start at around the onset of ripening. To investigate the transcriptional and posttranscriptional regulation of the ABA and synthetic auxin 1-naphthaleneacetic acid (NAA) on norisoprenoid production, we performed time series GC-MS and RNA-seq analyses on Cabernet Sauvignon grape berries from pre-veraison to ripening. more...

(Submitter supplied) Basal leaf removal has been widely practiced to increase cluster sunlight exposure, control berry rot and eventually improve grape berry quality. Early leaf removal performed in cool region appeared to benefit the accumulation of norisoprenoids and monoterpenes. However, effects of this canopy management and leaf moving on volatile profiles and transcriptome of grape berry in warm region characterized with strong sunshine and arid climate were paid less attention. more...

(Submitter supplied) Grapes (Vitis vinifera L.) are economically the most important fruit crop worldwide. However, the complexity of molecular and biochemical events that lead to ripening of nonclimacteric fruits is not fully understood. In particular the role of polyamines´ catabolism has been little explored. Ripening of Trincadeira grapes submitted to mock and guazatine treatments, a potent inhibitor of polyamine oxidase activity, was studied taking into account the transcriptional and metabolic profilings complemented with biochemical data. more...

(Submitter supplied) To understand the fruit changes and mechanisms involved in the compatible grapevine-virus interaction, we analyzed the berry transcriptome in two stages of development (veraison and ripening) in the red wine cultivar Cabernet Sauvignon infected with Grapevine leaf-roll-associated virus-3 (GLRaV-3). Analysis of global gene expression patterns indicate incomplete berry maturation in infected berries as compared to uninfected fruit suggesting viral infection interrupts the normal berry maturation process. more...

(Submitter supplied) We conducted transcript profiling and metabolome profiling induced by UV irradiation in grape berry skin. Transcriptome analysis was carried out with genome-wide microarray and two hundred thirty eight genes were more than 5-fold up-regulated by UV irradiation. The enrichment analysis showed GO terms including stilbene synthase (STS) gene. Moreover, the principal component analysis (PCA) of metabolome analysis showed a compound, identified resveratrol, accumulated in grape berry skin specifically. more...

(Submitter supplied) Grapevine rupestris stem pitting-associated virus (GRSPaV) is a widespread virus affecting Vitis spp. Although it has established a compatible viral interaction in Vitis vinifera L. without the development of phenotypic alterations, it can occur as distinct variants that show different symptoms in diverse Vitis species. We investigated the changes induced by GRSPaV in V. vinifera cv Bosco, an Italian white grape variety, by combining agronomic, physiological, and molecular approaches, in order to provide comprehensive information about the global effects of GRSPaV. more...
