Project description:Plants have great potential to protect against pathogens and other abiotic stress, and thus the interaction between signaling networks of defense is incredible. This can be activated and express with the application of growth elicitors and antimicrobial natural compounds. In the present study we used natural polysaccharide, Chitosan (15kDa) against Grey mold in two grape varieties (Shine-muscat and Kyoho). The finding depicted that the interaction of DEG and KEGG in control and treated samples of grapevine, which provides the evidence for selection of gray mold related defense genes and chitosan for subsequent grapevine production/postharvest programs.

Project description:Flavor and aroma play a major role in the perceived quality of grapes and wines. Among the most important compounds determining the oenological quality are monoterpenes. They confer typical floral notes to ‘Muscat’ varieties and, to a lesser extent, to other aromatic varieties. In recent years an increasing number of studies on the biosynthesis of terpenes in grape led to the identification and functional characterization of some enzymes and genes in this pathway. However, the underlying genetic map is still far from being complete. For example, the specific steps of monoterpene metabolism and its regulation are not known. With the aim of identifying new candidates for the missing links, we applied an integrative functional genomics approach based on the targeted metabolic and genome-wide transcript profiling of Moscato Bianco ripening berries. In particular, gas chromatography-mass spectrometry analysis of free and bound terpenoid compounds was combined with microarray analysis (14,562 probes) in the skins of berries collected at five developmental stages from pre-véraison to over-ripening. Differentially expressed metabolites and probesets were identified in the pairwise comparison between time points by using the early stage as a reference. Metabolic and transcriptomic data were integrated through pairwise correlation and clustering approaches to discover genes linked with particular metabolites or groups of metabolites. Finally, the candidate transcripts were checked for co-localization with QTLs controlling the level of aromatic compounds. The results provided novel insights into the biological networks of grapevine secondary metabolism, both at the regulatory and catalytic levels, and yielded a collection of previously undescribed genes related to the accumulation of target metabolites.

Project description:We used Illumina RNA-Seq technology to carry out digital gene expression profiling of Dormant and non dormant buds of Shine Muscat Cultivar.127 pathways were annotated by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and metabolic, biosynthesis of secondry metabolite and. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis demonstrated that DEGs were involved in various metabolic processes, including phytohormone metabolism. The newly generated transcriptome and gene expression profiling data provide valuable genetic information for revealing transcriptomic variation during dormant and non dormant period in Grapevine and ultimately helpful in uplifting of table grape industry.

Project description:Basal leaf removal has been widely practiced to increase cluster sunlight exposure, control berry rot and eventually improve grape berry quality. Early leaf removal performed in cool region appeared to benefit the accumulation of norisoprenoids and monoterpenes. However, effects of this canopy management and leaf moving on volatile profiles and transcriptome of grape berry in warm region characterized with strong sunshine and arid climate were paid less attention. To cope with multiple possible effects caused by global warming, researches in warm region are urgently needed to provide a guide for adjusting the sunlight exposure treatment to adapt the climate change.In Manas county of Xinjiang province, sunlight exposure treatments performed in this study resulted in decreased β-carotene and lutein, which mainly responsible for the reduced norisoprenoids in ripening grapes. Substrate competition due to the up-regulation of VvTPS-a and VvNCED3 may contribute to the decreased concentration of monoterpenes in exposed berries. The notable increased C6 alcohols in the grape berries treated by leaf removal applied at veraison (LR-V), was mainly attribute to the enhanced substrate availability of linoleic acid and linolenic acid together with the higher expression of VvLOXO and VvADH1. Free C6 aldehyde was reduced by half leaf removal applied at veraison (HLR-V), leaf moving at veraison (LM-V) and leaf removal applied at berry pepper-corn size (LR-PS). Moreover, transcriptomic analysis indicated that both LR-V and LM-V treated grape berry implemented multiple stress-mitigation strategies to acclimate the improved sunlight exposure. Interestingly, photosynthesis-related genes in grape berry were primarily up-regulated by LR-V as a consequence of carbohydrate source removal rather than improved sunlight exposure. Weighted gene co-expression network analysis (WGCNA) suggested that the genes encoding malate synthase and 3-oxoacyl-(acyl carrier protein) reductase show a significant correlation with the accumulation of C6 alcohol.

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: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?36 and 38 stages of Muscat Blanc a Petits Grains grape berries from Changli (CL, eastern) and Gaotai (GT, western). Transcriptome analysis revealed that some key genes involved in terpene synthesis were markedly up-regulated in the CL region. Particularly in the MEP pathway, the expression of VvHDR (1-hydroxy-2-methyl-2-butenyl 4-diphosphate reductase) paralleled with the accumulation of terpenes, which can promote the flow of isopentenyl diphosphate (IPP) into the terpene synthetic pathway. The glycosidically bound monoterpenes accumulated differentially along with maturation in both regions, which is synchronous with the expression of a monoterpene glucosyltransferase gene (VvGT14). Other genes were also found to be related to the differential accumulation of terpenes and monoterpene glycosides in the grapes between regions. Transcription factors that could regulate terpene synthesis were predicted through gene co-expression network analysis. Additionally, the genes involved in abscisic acid (ABA) and ethylene signal responses were expressed at high levels earlier in GT grapes than in CL grapes. cDNA libraries generated from four developmental stages (E-L 31, 35, 36 and 38) of Muscat Blanc a Petits Grains grape berries in two consecutive years from Changli (CL) and Gaotai (GT) in China were sequenced using Illumina HiSeq™ 2000.Only one RNA-seq library was constructed for each of the E-L31 and E-L36 stage samples because of the small amount of high quality RNA acquired, whereas two libraries were constructed for each of the E-L35 and E-L38 stage samples. As a result, a total of 24 libraries were obtained for the two regions within two years.

Project description:Plant volatiles can mediate plant-plant communication in the sense that plants attacked by herbivores can signal their unattacked neighbors of danger by emitting HIPVs. We call this the priming effect. Since the plant defense response is a systematic process involving numerous pathways and genes,to characterize the priming process, a time course study using a genome-wide microarray may provide more accurate information about the priming process. Furthermore, to what extent do the priming process and direct defense share similar gene expression profiles or pathways are also not clear. We used microarray to detect the priming effect of plant volatiles to healthy Arabidopsis thaliana, and the effect of direct leafminer feeding to Arabidopsis thalianas. A system using Lima bean plants, from which HIPVs can be effectively induced by leafminer feeding, as emitters and Arabidopsis thaliana as receivers is used to track the priming process between neighbor plants. The Arabisopsis thaliana seedlings were treated by volatiles from leafminer fed lima bean for 24h or 48h for RNA extraction and hybridization on Affymetrix microarrays. The Arabisopsis thaliana seedlings fed by leafminer directly were also collected The for RNA extraction and hybridization on Affymetrix micorarrays. We want to explore the response of Arabidopsis thaliana to priming volatiles during a 24h-48h time course. We also want to compare the effect of priming and direct leafminer feeding.
