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.

Project description: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 âNortonâ, 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. Furthermore, Norton berries develop a remarkably high level of resistance to most fungal pathogens while Cabernet Sauvignon berries remain susceptible to those pathogens. The distinct characteristics of Norton and Cabernet Sauvignon merit a comprehensive analysis of transcriptional regulation and metabolite pathways. Results: A microarray study was conducted on transcriptome changes of Norton berry skin during the period of 37 to 127 days after bloom, which represents berry developmental phases from herbaceous growth to full ripeness. Samples of six berry developmental stages were collected. Analysis of the microarray data revealed that a total of 3,352 probe sets exhibited significant differences at transcript levels, with two-fold changes between at least two developmental stages. Expression profiles of defense-related genes showed a dynamic modulation of nucleotide-binding site-leucine-rich repeat (NBS-LRR) resistance genes and pathogenesis-related (PR) genes during berry development. Transcript levels of PR-1 in Norton berry skin clearly increased during the ripening phase. As in other grapevines, genes of the phenylpropanoid pathway were up-regulated in Norton as the berry developed. The most noticeable was the steady increase of transcript levels of stilbene synthase genes. Transcriptional patterns of six MYB transcription factors and eleven structural genes of the flavonoid pathway and profiles of anthocyanins and proanthocyanidins (PAs) during berry skin development were analyzed comparatively in Norton and Cabernet Sauvignon. Transcriptional patterns of MYB5A and MYB5B were similar during berry development between the two varieties, but those of MYBPA1 and MYBPA2 were strikingly different, demonstrating that the general flavonoid pathways are regulated under different MYB factors. The data showed that there were higher transcript levels of the genes encoding flavonoid-3´-O-hydroxylase (F3´H), flavonoid-3´,5´-hydroxylase (F3´5´H), leucoanthocyanidin dioxygenase (LDOX), UDP-glucose:flavonoid 3´-O-glucosyltransferase (UFGT), anthocyanidin reductase (ANR), leucoanthocyanidin reductase (LAR) 1 and LAR2 in berry skin of Norton than in those of Cabernet Sauvignon. It was also found that the total amount of anthocyanins was markedly higher in Norton than in Cabernet Sauvignon berry skin at harvest, and five anthocyanin derivatives and three PA compounds exhibited distinctive accumulation patterns in Norton berry skin. Conclusions: This study provides an overview of the transcriptome changes and the flavonoid profiles in the berry skin of Norton, an important North American wine grape, during berry development. The steady increase of transcripts of PR-1 and stilbene synthase genes likely contributes to the developmentally regulated resistance during ripening of Norton berries. More studies are required to address the precise role of each stilbene synthase gene in berry development and disease resistance. Transcriptional regulation of MYBA1, MYBA2, MYB5A and MYBPA1 as well as expression levels of their putative targets F3´H, F3´5´H, LDOX, UFGT, ANR LAR1, and LAR2 are highly correlated with the characteristic anthocyanin and PA profiles of Norton berry skin. These results reveal a unique pattern of the regulation of transcription and biosynthesis pathways underlying the viticultural and enological characteristics of Norton grape, and yield new insights into the understanding of the flavonoid pathway in non-vinifera grape varieties. At each of six developmental stages, three biological replicates of berry samples were collected, each consists of ten randomly selected vines, a total of 18 samples were proccessed for analysis

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: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:Anthocyanins and flavonols are natural compounds that accumulate preferentially in grapevine flowers and fruits. They are among the most abundant flavonoids and play a very important role in grape and wine quality. In particular, they confer and stabilize colour and contribute to other organoleptic characteristics of the final product. Their complex profile in terms of concentration and relative abundance varies among cultivars and makes wine typicity. The synthesis of these compounds is mainly regulated at transcriptional level. Flavonoids accumulate at specific stages and in specific tissues during flower and berry development, as a consequence of the timely expression of the genes necessary for their synthesis. Although the general flavonoid pathway has been genetically and biochemically elucidated and the main determinants of colour have been identified, the molecular reasons of the fine variation among grape cultivars are still not completely understood. To shed light on this issue, extreme genotypes of a segregating population derived from the cross Syrah x Pinot Noir were characterized at transcriptional level. The transcriptome analysis along three berry developmental stages of these genotypes has allowed the identification of a large set of transcripts differentially modulated between the two groups. A population derived from M-bM-^@M-^XSyrahM-bM-^@M-^Y x M-bM-^@M-^XPinot NoirM-bM-^@M-^Y consisting of 170 F1 individuals plus the parental lines was characterized for the content of flavonols and anthocyanins in the skins of mature berries (38E-L; 18M-BM-0Brix). Based on the biochemical data, 4 high- and 4 low-flavonol producers (HFPs and LFPs: F1 16, F1 56, F1 63, F1 223 and F1 64, F1 256, F1 260, PN), two of which having also either very high or very low anthocyanin content (HAPs and LAPs: F1 63, F1 223 and F1 256, F1 260), were selected for gene expression analysis. A representative sample for each individual (one biological replicate) was collected at three berry developmental stages (hard green berry (33E-L, PV), veraison (35E-L, 50% coloured berries, VER) and maturity (38E-L, 18M-BM-0Brix, MAT)) during the 2007 season.
