“…v.75, n.5, p.381-386, September/October 2018 ABA applications did not modify any wine composition parameter (Table 1) except the alcoholic grade, which increased in treated grapes compared to untreated controls in 2005 (13 % versus 11%, p < 0.05) and 2006 (12 % versus 11 %, p < 0.05). Contrary to these results, Luan et al (2014) have showed that ABA treatments decreased the TA and increased pH of 'Yan 73' and 'Cabernet Sauvignon' red wines, compared with the controls.…”

Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of 'Verdejo' white grapes, and on the quality of their wines. To attain this objective, a field trial was carried out in a 'Verdejo'/110 Richter vineyard located in north-central Spain. Two levels of ethephon (0 and 1500 mg L −1) and ABA (0 and 800 mg L −1) were sprayed on clusters at veraison, in a factorial design for three consecutive seasons. Ethephon and ABA had additive effects, decreasing titratable acidity and increasing pH of the must, which could be exploited by accelerating the grape ripening process in cold-climate zones. Nevertheless, each growth regulator affected the composition and sensory analysis of the wines differently. Ethephon treatments produced wines with lower concentration of acids and better flavor quality than those made from untreated plants, while wines with ABA applications tended to have a higher ethanol concentration and poorer aroma quality than controls. The wines submitted to treatments with ethephon obtained the best overall evaluation in the sensory analysis throughout the trial.

“…During berry development, the VvANR mRNA level was increased markedly in the EBR treatments (EBR + D, EBR + L), which contributed to the higher levels of VvLAR1 and VvLAR2 mRNA under different conditions. These effects of EBR were similar to those of abscisic acid (ABA) and methyl jasmonate (JA) on the synthetic process of proanthocyanidins and anthocyanins [ 48 , 49 , 50 ]. In grapes, VvMYB5a and VvMYB5b were transcriptional regulators related to PA metabolism [ 15 , 51 ], and previous studies have already identified VvMYBPA1 and VvMYBPA2 as the transcription factors involved in the regulation of the proanthocyanidin pathway during grape development [ 52 , 53 ].…”

Anthocyanins and proanthocyanidins (PAs) are crucial factors that affect the quality of grapes and the making of wine, which were stimulated by various stimuli and environment factors (sugar, hormones, light, and temperature). The aim of the study was to investigate the influence of exogenous 24-Epibrassinolide (EBR) and light on the mechanism of anthocyanins and PAs accumulation in grape berries. Grape clusters were sprayed with EBR (0.4 mg/L) under light and darkness conditions (EBR + L, EBR + D), or sprayed with deionized water under light and darkness conditions as controls (L, D), at the onset of veraison. A large amount of anthocyanins accumulated in the grape skins and was measured under EBR + L and L treatments, whereas EBR + D and D treatments severely suppressed anthocyanin accumulation. This indicated that EBR treatment could produce overlay effects under light, in comparison to that in dark. Real-time quantitative PCR analysis indicated that EBR application up-regulated the expression of genes (VvCHI1, VvCHS2, VvCHS3, VvDFR, VvLDOX, VvMYBA1) under light conditions. Under darkness conditions, only early biosynthetic genes of anthocyanin biosynthesis responded to EBR. Furthermore, we also analyzed the expression levels of the BR-regulated transcription factor VvBZR1 (Brassinazole-resistant 1) and light-regulated transcription factor VvHY5 (Elongated hypocotyl 5). Our results suggested that EBR and light had synergistic effects on the expression of genes in the anthocyanin biosynthesis pathway.

“…In addition to its role in defense against particular plant pathogens, there is some evidence that stilbenoids could also contribute to improved tolerance to abiotic stress. For example, osmotic stress ( Deis et al, 2011 ; Hatmi et al, 2014 ) and exogenous application of ABA ( Luan et al, 2014 ), which is known to contribute to osmotic stress tolerance, increased the accumulation of stilbenes in wine grape. Furthermore, citrus seedlings treated with exogenous resveratrol exhibited reduced NaCl-derived membrane permeability and MDA accumulation ( Kostopoulou et al, 2014 ), which correlates well with the fact that VqSTS21 transgenic Arabidopsis lines displayed decreased MDA content in response to osmotic stress ( Figure 6F ).…”

Expression of the Grape VqSTS21 Gene in Arabidopsis Confers Resistance to Osmotic Stress and Biotrophic Pathogens but Not Botrytis cinerea

Stilbene synthase (STS) is a key gene in the biosynthesis of various stilbenoids, including resveratrol and its derivative glucosides (such as piceid), that has been shown to contribute to disease resistance in plants. However, the mechanism behind such a role has yet to be elucidated. Furthermore, the function of STS genes in osmotic stress tolerance remains unclear. As such, we sought to elucidate the role of STS genes in the defense against biotic and abiotic stress in the model plant Arabidopsis thaliana. Expression profiling of 31 VqSTS genes from Vitis quinquangularis revealed that VqSTS21 was up-regulated in response to powdery mildew (PM) infection. To provide a deeper understanding of the function of this gene, we cloned the full-length coding sequence of VqSTS21 and overexpressed it in Arabidopsis thaliana via Agrobacterium-mediated transformation. The resulting VqSTS21 Arabidopsis lines produced trans-piceid rather than resveratrol as their main stilbenoid product and exhibited improved disease resistance to PM and Pseudomonas syringae pv. tomato DC3000, but displayed increased susceptibility to Botrytis cinerea. In addition, transgenic Arabidopsis lines were found to confer tolerance to salt and drought stress from seed germination through plant maturity. Intriguingly, qPCR assays of defense-related genes involved in salicylic acid, jasmonic acid, and abscisic acid-induced signaling pathways in these transgenic lines suggested that VqSTS21 plays a role in various phytohormone-related pathways, providing insight into the mechanism behind VqSTS21-mediated resistance to biotic and abiotic stress.
