Project description:Transcriptional profiling comparing untreated berries (control) with berries treated with NAA (1-Naphthalene acetic acid, an auxin) at the preveraison stage. Two-condition experiment: control vs. treated. Comparisons were as follows: NAA-treated berries at 60 (days after full bloom (DAFB)) versus untreated berries at 60 DAFB (2 biological replicates, both dye-swapped), NAA-treated berries at 60 DAFB versus NAA-treated berries at 110 DAFB (2 biological replicates, only one dye-swapped), NAA-treated berries at 110 DAFB versus untreated berries at 110 DAFB (2 biological replicates, only one dye-swapped), and NAA-treated berries at 148 DAFB versus untreated berries at 110 DAFB (2 biological replicates, only one dye-swapped).

Project description:We would like to know how symbiotic molecules such as Nod Factors (NF) influence lateral root (LR) development in M. truncatula. We have preliminary evidence that this action is through early stages of root development. Auxin is the major phytohormone controlling LR development and we also have evidence that NF interfere with auxin for the control of LR development. This transcriptomic study aims at finding new molecular targets that would be responsive to auxin and NF treatment, even at a higher level by the combination of both auxin and NF. Such targets could be involved in the control or early development stages of LR that would be controlled both by auxin and NF treatment. - 2 day old M. truncatula (accession A17) plantlets grown on M medium were transferred for 2 days on M medium+ 10-5M NPA (1-N-Naphthylphthalamic acid, auxin transport inhibitor) then transferred for 10 h on M medium containing 10-6 M NAA (naphthalene-1-acetic acid, permeant auxin analog) or 10-7 M Nod factors (NF) or a combination of both (10-6 M NAA + 10-7 M NF). These are compared to mock treated (solvent only) plants. 12plex_med_2013_04 12 dye-swap - treated vs untreated comparison

Project description:The abscisic acid (ABA) increase and auxin decline are both indicators of ripening initiation in grape berry, and norisoprenoid accumulation also start at around the onset of ripening. To investigate the transcriptional and posttranscriptional regulation of the ABA and synthetic auxin 1-naphthaleneacetic acid (NAA) on norisoprenoid production, we performed time series GC-MS and RNA-seq analyses on Cabernet Sauvignon grape berries from pre-veraison to ripening. Higher levels of free norisoprenoids were found in ABA-treated mature berries in two consecutive seasons, and both free and total norisoprenoids were significantly increased by NAA in one season. The expression pattern of known norisoprenoid-associated genes in all samples and the up-regulation of specific alternative splicing isoforms of VviDXS and VviCRTISO in NAA-treated berries were predicted to contribute to it. Combined weighted gene co-expression network analysis (WGCNA) and promoter motif prediction analysis suggested that GATA26 and GATA28 could be potential regulators of norisoprenoid accumulation. Finally, the network analysis uncovered the interaction between previously identified switch genes, hormone-related genes and norisoprenoid-associated genes.

Project description:Sulphur is used as a food preservative, especially throughout the table grape and wine industries, <br>however there is increasing concern as to the health rises associated with human consumption. <br>Thus, we investigated the transcript abundance changes in grapes treated with sulfur dioxide and <br>other preservative compounds, compared to control treatments. Export quality, red-skinned M-^QCrimson<br> SeedlessM-^R grapes (Vitis vinifera L.) were harvested at commercial maturity from one vineyard <br>in the Swan Valley region of Western Australia. At least 15 kg grapes per treatment were <br>completely immersed in the treatment solution (? 1 min) and allowed to dry on racks before <br>being weighed in to 7 x 2 kg lined export cartons, without sulphur pads. Once packed, cartons <br>were immediately placed in 2 M-0C storage for up to 56 days and once cool, commercial <br>SO2-generating pads were placed into cartons for SO2 treatment. The salicylic acid (SA,<br> 25 mM), methyl jasmonate (MJ, 5mM) and their combination (25 mM SA + 5 mM MJ) were <br>dissolved in 0.5 % (v/v) dimethyl sulphoxide (DMSO). A 0.5 % solution of DMSO was used<br> as a control treatment. An additional, untreated control for sulphur-treated berries was used.<br>Microarrays were performed in duplicate for the 6 treatments, Sulfur dioxide (plus untreated <br>control), SA, MJ, and the combined SAMJ treatment (plus DMSO control) on grape berries <br>after 21 days of treatment post harvest. The results indcate a large scale re-programing of <br>the grape berry transcritpome, similar to that which has been observed for prolonged <br>exposure to harsh oxidative stress conditions.

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:Grapevine is a perennial crop often cultivated by grafting a scion cultivar on a suitable rootstock. Rootstocks influence scions, particularly with regard to water uptake and vigor. Therefore, one of the possibilities to adapt viticulture to the extended drought stress periods is to select rootstocks conferring increased tolerance to drought. However, the molecular mechanisms associated with the ability of rootstock/scion combination to influence grape berry metabolism under drought stress are still poorly understood. The transcriptomic changes induced by drought stress in grape berries (cv. Pinot noir) from vines grafted on either 110R (drought tolerant) or 125AA (drought sensitive) rootstock were compared. The experiments were conducted in the vineyard for two years and two grape berry developmental stages (50% and 100 % veraison. The genome-wide microarray approach showed that water stress strongly impacts gene expression in the berries, through ontology categories that cover cell wall metabolism, primary and secondary metabolism, signalling, stress, and hormones, and that some of these effects strongly depend on the rootstock genotype. Indeed, under drought stress, berries from vines grafted on 110R displayed a different transcriptional response compared to 125AA concerning genes related to jasmonate, phenylpropanoid metabolism and PR-proteins. The data also suggests a link between jasmonate and secondary metabolism in water-stressed berries. Overall, genes related to secondary metabolism and jasmonate are more induced and/or less repressed by drought stress in the berries grafted on the drought-sensitive rootstock 125AA. These rootstock-dependent gene expression changes are relevant for berry composition and sensory properties.

Project description:Changes in gene expression during berry development during a grape growing season were analysed. The effect on gene expression of different viticultural practises during grape berry development was investigated in this study by comparing two irrigation methods (standard versus prolonged deficit irrigation). Grape berries were collected and pooled on a weekly basis to obtaining a developmental series comprising of 17 developmental stages from flowering until harvest across the grape growing season for both standard and prolonged deficit irrigated vines. Gene expression patterns during development and between pruning treatments were obtained. Keywords: Time course, developmental series and treatments
