Time-course comparison of samples collected at three developmental stages (stages 33, 34 and 36 according to the modified E-L system, ref: Coombe BG, Aust J Grape Wine Res 1995, 1: 104-110) during three seasons (2003, 2005 and 2006). Data for each of the three seasons were normalized independently within each season, using gcRMA. 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) Background: The complex and dynamic changes during grape berry development have been studied in Vitis vinifera, but little is known about these processes in other Vitis species. The grape variety ‘Norton’, with a major portion of its genome derived from Vitis aestivalis, maintains high levels of malic acid and phenolic acids in the ripening berries in comparison with V. vinifera varieties such as Cabernet Sauvignon. more...

(Submitter supplied) The experiment was aimed at describing similarities and differences between grapevine flesh and skin ripening at the transcriptome level. Transcriptional profiles throughout flesh and skin ripening were followed in three biological replicas during two consecutive growing seasons in a table grape cultivar ‘Muscat Hamburg’. Berries were weekly picked off bunches (one bunch per vine from each selected vine) from june to august. 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) We used Affymetrix microarray analyses of thirty-two individual Vitis vinifera cv. Cabernet Sauvignon berries sampled from two clusters at fifty-percent ripening initiation. By delineating four developmental stages of ripening initiation, we demonstrate that color is a statistically significant indicator of transcriptional state during ripening initiation. We report on clustered gene expression patterns which were mined for genes annotated with signal transduction functions in order to advance regulatory network modeling of ripening initiation in grape berries. 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) 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) Auxin treatment of grape (Vitis vinifera L.) berries delays ripening by inducing changes in gene expression and cell wall metabolism and could combat some deleterious climate change effects. Auxins are inhibitors of grape berry ripening and their application may be useful to delay harvest to counter effects of climate change. However, little is known about how this delay occurs. The expression of 1892 genes was significantly changed compared to the control during a 48 h time-course where the auxin 1-naphthaleneacetic acid (NAA) was applied to pre-veraison grape berries. more...

(Submitter supplied) Grapevine (Vitis vinifera L.) is a model for the investigation of physiological and biochemical changes during the formation and ripening of non-climacteric fleshy fruits. However, the order and complexity of the molecular events during fruit development remain poorly understood. To identify the key molecular events controlling berry formation and ripening, we created a highly detailed transcriptomic and metabolomic map of berry development, based on samples collected every week from fruit-set to maturity in two grapevine genotypes for three consecutive years, resulting in 219 samples. 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) Light conditions significantly influence grape berry ripening and the accumulation of phenolic compounds, but the underlying molecular basis remains partially understood. Here, we applied integrated transcriptomics and pathway-level metabolomics analyses to investigate the effect of cluster bagging during various developmental stages on phenolic metabolism in Cabernet Sauvignon grapes. Bagging treatments had limited effects on berry quality attributes at harvest and did not consistently affect phenolic acid biosynthesis between seasons. more...

(Submitter supplied) 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 techniques, we report the first global transcriptomic analysis (integrated with agronomic and biochemical data) aiming to determine the molecular mechanisms that control Sangiovese berry composition. more...

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...
