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. Keywords: time course (berry development series)

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.

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.

Project description:Grapevine is a commercially important fruit crop that provides berries for direct consumption, juice pressing, drying (raisins), and fermentation to produce wine. The economic value of the crop has encouraged many researchers to study the physiological and molecular basis of berry development, particularly processes that affect wine quality. Post-harvest withering of grapevine berries is used in the production of dessert and fortified wines to alter must quality characteristics and to increase the concentration of simple sugars. Vitis vinifera cv Corvina berries were sampled during the 2006 growing season at four developmental time points and three additional time points during the 91-day post-harvest withering process. The four developmental time points were 59, 71, 98 and 112 days after fruit set, corresponding to pre-veraison, veraison, early ripening and late ripening, and the three withering time points (WI, WII and WIII) were 35, 56 and 91 days after harvest. Three biological replicates were taken at each time point resulting in a total of 21 samples.

Project description:Anthocyanins are flavonoid compounds responsible for red/purple colours in the leaves, fruit and flowers of many plant species. They are produced through a multistep pathway which is controlled by MYB transcription factors. VvMYBA1 and VvMYBA2 activate anthocyanin biosynthesis in grapevine (Vitis vinifera) and are non-functional in white grapevine cultivars. In this study, transgenic grapevines with altered VvMYBA gene expression were developed, and transcript analysis was carried out on berries using a microarray technique. The results showed that VvMYBA is a positive regulator of the later stages of anthocyanin synthesis, modification and transport in Shiraz. One up-regulated gene ANTHOCYANIN 3- O-GLUCOSIDE-6”-O-ACYLTRANSFERASE (Vv3AT) encodes a BAHD acyltransferase protein, belonging to a clade separate from most anthocyanin acyltransferases. Functional studies (in planta and in vitro) show that Vv3AT has a broad anthocyanin substrate specificity and can also utilise both aliphatic and aromatic acyl donors, a novel activity for this enzyme family found in nature. In V. vinifera cv. Pinot Noir, a red-berried grapevine mutant lacking acylated anthocyanins, Vv3AT contains a nonsense mutation encoding a truncated protein that lacks two motifs required for BAHD protein activity. Promoter activation assays confirm that Vv3AT transcription is activated by VvMYBA1, which adds to the current understanding of the regulation of the BAHD gene family. The flexibility of Vv3AT to use both classes of acyl donors will be useful in the engineering of anthocyanins in planta or in vitro.
