Comparative study on berry development of two grape cultivars by transcriptomic analyses [Victoria]

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.

Transcriptional profiling of two muscadine grape cultivars ‘Carlos’ and ‘Noble’ to reveal new genes, gene regulatory networks, and pathways that involved in grape berry ripening

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.

Comparative transcriptomic analysis between ‘Sanbenti’ and its bud sport ‘11-06-25’ during grape berry development stages

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.

Transcriptome analyses of grape berry skin induced by UV irradiation.

Project description:We conducted transcript profiling and metabolome profiling induced by UV irradiation in grape berry skin. Transcriptome analysis was carried out with genome-wide microarray and two hundred thirty eight genes were more than 5-fold up-regulated by UV irradiation. The enrichment analysis showed GO terms including stilbene synthase (STS) gene. Moreover, the principal component analysis (PCA) of metabolome analysis showed a compound, identified resveratrol, accumulated in grape berry skin specifically. Our result clearly shows that UV irradiation induced only accumulation of resveratrol and its analogues but did not induce accumulation of the other phenolic compounds.

Effect of different irrigation supply on gene expression of two table grape cultivars

Project description:Grapevine (Vitis vinifera L.) is importantly cultivated worldwide for table grape and wine production. Its cultivation requires irrigation supply, especially in arid and semiarid areas. Water deficiency can affect berry and wine quality mostly depending on the extent of plant perceived stress, which is a cultivar-specific trait. We tested the physiological and molecular responses to water deficiency of two table grape cultivars, Italia and Autumn royal, and we highlighted their different adaptation. Microarray analyses revealed that Autumn royal reacts involving only 29 genes, related to plant stress response and ABA/hormone signal transduction, to modulate the response to water deficit. Instead, cultivar Italia orchestrates a very broad response (we found 1037 genes differentially expressed) that modifies the cell wall organization, carbohydrate metabolism, response to reactive oxygen species, hormones and osmotic stress. For the first time we integrated transcriptomic data with cultivar-specific genomics and found that ABA-perception and –signalling are key factors mediating the varietal-specific behaviour of the early response to drought. We were thus able to isolate candidate genes for the genotype-dependent response to drought. These insights will allow the identification of reliable plant stress indicators and the definition of sustainable cultivar-specific protocols for water management.

grape berry vacuole proteomic - Quantitative Proteome Analysis Reveals Changes in the Protein Landscape During Grape Berry Development With a Focus on Vacuolar Transport Proteins

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.
