Analysis of gene expression changes involved in diurnal and circadian rhythms in grape berries. (DIU_05_circadian).

ABSTRACT: This is a microarray experiment to investigate changes in gene expression in deseeded berries from field grown vines to identify genes involved in diurnal and circadian effects. Changes in gene expression at two time points within a 24 hour cycle were analyzed to identify expression profiles that coincided with diurnal and circadian effects. The gene expression profiles were then to be compared between the two developmental time points T5 v T17). Keywords: Diurnal v Circadian

Analysis of gene expression in grape berries due to diurnal effects (DIU_05).

Project description:This is a 24 hour time course experiment to investigate changes in gene expression in deseeded berries sampled every three hours within a 24 hour period at 2 time points during development i.e. T5 (preveraison) & T17 (postveraison). Changes in gene expression within the 24 hour period were analyzed to identify expression profiles that coincided with diurnal changes. The gene expression profiles were then to be compared between the two developmental time points T5 v T17). Keywords: Diurnal time course

Grape skin transcriptome in the berries grown on the vine treated with exogenous abscisic acid

Project description:The experiment was conducted using grapevines of Cabernet Sauvignon grown in a field. At veraison, the clusters in the vines were sprayed with a 400 mgl-1(+)-abscisic acid (ABA) solution. The ABA treated berries and non-treated berries (control) were harvested at 14 and 28 days after veraison and peeled. PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Kazuya Koyama. The equivalent experiment is VV16 at PLEXdb. ABA treated - developmental stage name: 14 days after veraison(3-replications); ABA treated - developmental stage name: 28 days after veraison(3-replications); untreated (control) - developmental stage name: 14 days after veraison(3-replications); untreated (control) - developmental stage name: 28 days after veraison(3-replications)

Transcription profiling of grape berries during ripening initation

Project description: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. We also demonstrated that gene expression does not differ statistically significantly at a global level in berries sampled from different plants or different positions in a cluster. Experiment Overall Design: Individual grape berries were selected at 4 developmental stages along ripening initiation for RNA extraction and hybridization to Affymetrix Vitis Genome GeneChips. One goal of this study was to determine the association between the global transcriptome state and phenotypic variables frequently used in berry staging such as color and firmness, so we defined the four time-points (development series) by color/firmness combinations: green hard (GH), green soft (GS), pink soft (PS) and red soft (RS). Individual berries representing each stage were collected from either the distal or the proximal position of one cluster one each of two plants used for experiments.

Transcription profiling of grape berries during ripening

Project description:Grape berries undergo considerable physical and biochemical changes during the ripening process. Ripening is characterized by a number of changes, including the degradation of chlorophyll, an increase in berry deformability, a rapid increase in the level of hexoses in the berry vacuole, an increase in berry volume, the catabolism of organic acids, the development of skin colour, and the formation of compounds that influence flavour, aroma, and therefore, wine quality. The aim of this work is to identify differentially expressed genes during grape ripening by microarray and real-time PCR techniques. Using a custom array of new generation, we analysed the expression of 6000 grape genes from pre-veraison to full maturity, in Vitis vinifera cultivar Muscat of Hamburg, in two different years (2006 and 2007). Five time points per year and two biological replicates per stadium were considered. To reduced intra-plant and inter-plant biological variability, for each ripening stadium we collected around hundred berries from several bunch grapes of five plants of V. vinifera cv Muscat of Hamburg. We will use the real-time PCR technique to validate microarray data.Muscat of Hamburg. We will use the real-time PCR technique to validate microarray data.

Gene expression analysis in grape berries at veraison (SIB_06)

Project description:A bunch of grapes at veraison is comprised of berries at different stages of development ranging from hard green to soft red. Veraison represents an important transition stage in the ripening process where key genes may be switched on or off. Single berries at various stages of development from hard green to soft red were collected at a single time point from a single bunch of grapes going through veraison. Gene expression patterns were obtained from single berries representing different developmental stages. Keywords: Developmental series

Transcriptome Comparison of Cabernet Sauvignon Grape Berries from Two Regions with Distinct Climate

Project description:Primary and secondary metabolism in grape berries is under the control of complex interactions among environmental conditions, genotypes, and management practices. To obtain an interpretation from the view of transcriptome on distinct metabolite accumulation between ecologically different regions in China, next-generation sequencing technology was performed on E-L 31, 35, and 38 stages of Cabernet Sauvignon grape berries from Changli (CL, eastern) and Gaotai (GT, western). The transcript abundance of epoxycarotenoid dioxygenase and xanthoxin dehydrogenase required for ABA biosynthesis was significantly higher in the GT berries at E-L 35 and 38 stages compared with the CL berries, which may explain the relatively short maturation period of berries in the western region. Some genes required for carbohydrate metabolism, such as hexose transporter, L-idonate dehydrogenase, and phosphoenolpyruvate carboxylase, were significantly up-regulated in the CL berries in relation to the GT berries, which positively correlated with the sugar and organic acid accumulations. Pathway enrichment analysis of differentially expressed genes revealed that the CL berries had higher levels of phenylpropanoid biosynthesis at E-L 38 stage than the GT berries, which may relate to the quick fading of the GT wines because of weak co-pigmentation. This observation lays a foundation for further study concerning the molecular basis for environmental effects on berry quality formation.
