Project description:Peach is a climacteric fruit whose ripening is largely dependent on ethylene. Recently, it has been shown that auxin is able to autonomously regulate the expression of ripening related genes, and that a cross-talk between ethylene and auxin occurs during the ripening process. By using the non-destructing index of absorbance difference (IAD), mature nectarines were homogeneously grouped into three classes (0, 1 and 2) according to their ripening phase and treated with 1-methylcyclopropene (1-MCP), known to block ethylene receptors. 1-MCP responses differed in the three classes that were thus used to molecularly investigate the auxin-ethylene cross-talk during the transition from maturation to ripening and the accompanying switch of ethylene biosynthesis from System-1 to System-2. Microarray experiments showed that 1-MCP modified the expression of 121 genes (63 were up-regulated and 59 down-regulated). Besides inducing ethylene-, auxin- and ripening-repressed genes and repressing ethylene-, auxin- and ripening-induced genes, also genes induced by ripening, auxin and 1-MCP were discovered. The up-regulating effect of 1-MCP was observed for ctg134, similar to signalling peptides, for 1-aminocyclopropane-1-carboxylic acid synthase 1 (ACS1) and, interestingly, for many auxin-regulated genes, such as GH3, whose expression is widely used as a marker for free auxin. The latter finding, together with the induction of an IAA amidohydrolase, suggests that the 1-MCP application could have caused a rise in free auxin, thus leading to an increase in ethylene biosynthesis through the induction of the tightly regulated ACS1 gene.

Project description:Berry skin total protein from Cabernet Sauvignon, Merlot, Pinot Noir, Chardonnay and Semillon. Treatments were control (well-watered) versus restricted irrigation (water-deficit). Samples were taken from harvest-ripe whole berry clusters following a seasonal water deficit in treatment vines. A comparative analysis between the cultivars and treatments was performed.

Project description:Temperature and solar radiation influence Vitis vinifera L. berry ripening. Both environmental conditions fluctuate cyclically on a daily period basis and the strength of this fluctuation affects grape ripening too. Additionally, a molecular circadian clock regulates daily cyclic expression in a large proportion of the plant transcriptome modulating multiple developmental processes in diverse plant organs and developmental phases. Circadian cycling of fruit transcriptomes has not been characterized in detail despite their putative relevance in the final composition of the fruit. Thus, in this study, gene expression throughout 24 h periods in pre-ripe berries of Tempranillo and Verdejo grapevine cultivars was followed to determine whether different ripening transcriptional programs are activated during certain times of day in different grape tissues and genotypes. Results: Microarray analyses identified oscillatory transcriptional profiles following circadian variations in the photocycle and the thermocycle. A higher number of expression oscillating transcripts were detected in samples carrying exocarp tissue including biotic stress-responsive transcripts activated around dawn. Thermotolerance-like responses and regulation of circadian clock-related genes were observed in all studied samples. Indeed, homologs of core clock genes were identified in the grapevine genome and, among them, VvREVEILLE1 (VvRVE1), showed a consistent circadian expression rhythm in every grape berry tissue analysed. Light signalling components and terpenoid biosynthetic transcripts were specifically induced during the daytime in Verdejo, a cultivar bearing white-skinned and aromatic berries, whereas transcripts involved in phenylpropanoid biosynthesis were more prominently regulated in Tempranillo, a cultivar bearing black-skinned berries. Conclusions: The transcriptome of ripening fruits varies in response to daily environmental changes, which might partially be under the control of circadian clock components. Certain cultivar and berry tissue features could rely on specific circadian oscillatory expression profiles. These findings may help to a better understanding of the progress of berry ripening in short term time scales.

Three different circadian time course series consisted on six time point each. Series corresponded to pericarp of Verdejo grapevine cultivar and berry flesh and skin in separate of Tempranillo cultivar. Three biological replicates were analyzed for each series.
