Project description:Vitis vinifera endogenous small RNAs Size fractionated small RNA from total RNA extracts of Vitis vinifera leaves, inflorescences, tendrils and small berries were ligated to adapters, purified again and reverse transcribed. After PCR amplification the sample was subjected to Solexa/Illumina high throughput pyrosequencing. Please see www.illumina.com for details of the sequencing technology.

Project description:we analyzed pathogen-induced changes in the transcriptome of Vitis vinifera ‘Cabernet sauvignon’ and Vitis aestivalis ‘Norton’ by conducting a large-scale study to measure transcript abundance at 0, 4, 8, 12, 24, and 48 hours post-treatment in conidiospore- and mock-inoculated leaves using Affymetrix GeneChip Vitis vinifera Genome Array Keywords: time course
Project description:Vitis vinifera RNA degradome Isolated polyadenylated RNA from total RNA extracts of Vitis vinifera leaves, were ligated to 5'-adapter that include san MmeI recognition site. The ligated products were purified again, reverse transcribed and cleaved with MmeI. The 5' fragments were purified from gel and to a 3'- dsDNA adapter and PCR amplified. After PCR amplification the sample was subjected to Solexa/Illumina high throughput pyrosequencing. Please see www.illumina.com for details of the sequencing technology.
Project description:Methods:transcriptomes of the different development stages of Vitis vinifera cv. Cabernet Sauvignon and Vitis quinquangularis accession Danfeng-2 were analyzed using Illumina Hiseq 2500. The sequence reads that passed quality filters were analyzed: TopHat followed by Cufflinks. mRNA profiles of different development stages of Vitis vinifera cv. Cabernet Sauvignon and Vitis quinquangularis accession Danfeng-2 were generated by deep sequencing, in triplicate, using Illumina Hiseq 2500.
Project description:The aim of this quantitative label-free shotgun proteomic experiment is to perform a comparative study of two different sample preparation methods which employ two different pre-fractionation techniques (SDS-PAGE and FASP-GPF) for use in shotgun proteomic analysis of Vitis riparia leaf material with concurrent label-free quantitation in order to optimise a technique that would facilitate identification of most number of proteins and produce useful biological information, when searched against the Vitis vinifera database.
Project description:Infection by the pathogen grape powdery mildew (Erysiphe necator) causes changes in the transcriptome of its susceptible host Vitis vinifera. Infection triggers the host to synthesize the signaling molecule salicylic acid (SA) which regulates the expression of a broad range of defense-related plant genes. In addition, it is hypothesized that E. necator directly modulates gene expression in V. vinifera via the haustorial complex. This microarray experiment was designed to dissect host transcriptome changes triggered directly by E. necator infection and indirectly through the SA response. We accomplished this by conducting two separate global leaf transcriptome analyses using the Vitis Affymetrix GeneChip platform: in one, we compared the leaves with fully established PM colonies to healthy reference leaves, in another, we compared healthy leaves with artificially elevated SA levels to healthy reference leaves. Overlaying host transcriptome changes from these two experiments enabled us to glean out V. vinifera genes that modulate their expression in response E. necator in an SA-independent manner.
