Project description:Grape Berry Ripening Signature Gene Expression Analysis
| PRJNA533801 | ENA
Project description:This microarray experiment provides data which shows of the effects on gene expression from the artificial application of certain hormones on their own or in combination on ripening berries from the Adelaide Hills Various hormones have been implicated as having an effect on the grape berry ripening process. Their application prior to ripening may change the gene expression profile at veraison. The identification of the genes which are expressed at different levels due to the various hormone treatments may give insight to key gene expression changes in the ripening process.

Project description:In commercial fruit production, synchronized ripening and stable shelf life are important properties. The loosely clustered or non-bunching muscadine grape has unrealized potential as a disease resistant cash crop, but requires repeated hand harvesting due to its unsynchronized or long or heterogeneous maturation period. Genomic research can be used to identify the developmental and environmental factors that control fruit ripening and postharvest quality. This study coupled the morphological, biochemical, and genetic variations between ‘Carlos’ and ‘Noble’ muscadine grape cultivars with RNA-sequencing analysis during berry maturation. The levels of antioxidants, anthocyanins, and titratable acids varied between the two cultivars during the ripening process. We also identified new genes, pathways, and regulatory networks that modulated berry ripening in muscadine grape. These findings may help develop a large-scale database of the genetic factors of muscadine grape ripening and postharvest profiles and allow the discovery of the factors underlying the ripeness heterogeneity at harvest. These genetic resources may allow us to combine applied and basic research methods in breeding to improve table and wine grape ripening uniformity, quality, stress tolerance, and postharvest handling and storage.

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:Taste and color, which are important organoleptic qualities of grape berry, undergo rapid and substantial changes during development and ripening. In this study, we use two cultivars ‘Sanbenti’ and its bud sport ‘11-06-25’ to explore expression profiles differences and identify genes associated with total soluble solid (TSS) and total anthocyanins during grape berry development stages using RNA sequencing.

Project description:The vacuole occupies a large portion of plant cell volume, it is especially true to fruit tissues. Berry flesh cell vacuole serves as storage organelle for water, sugars, acids, secondary metabolites and others, which largely determining berry quality (Fontes et al., 2011a, b; Shiratake and Martinoia, 2007, Conde et al., 2006). However, the molecular basis of these compartmentation processes is still poorly understood. As in many species, the major bottle neck to study these aspects in grapevine is to obtain highly purified vacuoles with a good yield (Fontes et al., 2010). Up to date, several vacuole or tonoplast proteome researches were applied on a few plants mainly on Arabidopsis thaliana, vacuoles or tonoplast were derived from mesophyll cells (Carter et al., 2004, Endler et al., 2006, Schulze, et al., 2012) or cell culture (Jaquinod et al 2006, Shimaoka et al 2004), cauliflower buds (Schmidt et al., 2007) and sugar beet taproots (Jung et al., 2015). Though the grape berry protoplasts and intact vacuoles were successfully isolated from Cabernet Sauvignon berry suspension-cultured cells (Fontes et al., 2010), the vacuoles isolated from grape berry or different development and ripening stages of grape berry mesocarp tissues were not achieved.

Project description:Grapevine is a popular fruit crop worldwide with essential economic importance. The grape berry undergoes complex biochemical changes from fruit set until ripening. To better understand this dynamic process, we applied mass spectrometry based platforms to analysis the metabolome and proteome of grape berries at 12 developmental stages covering the whole developmental process of grape berries. Primary metabolites involved in central carbon metabolism such as sugars, organic acids and amino acids metabolism together with various bioactive secondary metabolites like flavonols, flavan-3-ols and anthocyanins were annotated and quantified. At the same time, the proteomic analysis revealed the protein dynamics of the developing grape berries. Multivariate statistical analysis of the metabolomic and proteomic data revealed growing trajectories with minor difference indicating that grape berry development is a sequential process resulting in changes in all examined processes. The incorporation of the metabolomic and proteomic results allowed us to schematize representative metabolome and proteome candidates on sugar, glycolysis, TCA cycle, amino acid, phenylpropanoid, flavonoid biosynthetic pathways. The overview of the metabolism dynamics on both protein and metabolite level unveiled the metabolism switch and adjustments during grape berry development.

Project description:Grape berry development is a highly coordinated, intricate and complex process with many morphological, biochemical and physiological changes occurring during the ripening process. Equally, ripening is an organoleptic characteristic linked to fruit development. The fruits Seedless (FS) and Victoria (VT) grape varieties exhibit many morphological and phytochemical differences, but genetic mechanisms underlying them remain poorly explored. Herein, we comparatively analysed the phenotypic and transcriptomic patterns of Victoria (VT) and Flame Seedless (FS) grape varieties during berry development. We studied the physiological analysis and transcriptomic profiles sequencing were performed at four berry developmental stages time-points (40, 50, 60 and 80 DPA). Notably, the VT variety berry size was comparatively larger to the FS variety. At maturity, 80DPA, the FS soluble solids were 61.8% higher than VT. Further, a total of 4889 and 2802 DEG’s were identified from VT and FS 40 DPA to 80 DPA development stages, respectively. 1386 DEGs were common in the two varieties. GO analysis identified Cysteine biosynthetic process, response to red light, chlorophyll binding, polysaccharide biosynthetic process and chloroplast thylakoid membrane as some of the dominant terms under the biological processes, molecular function and cellular component categories.
