“…Ozone absorption coefficient drops rapidly at wavelengths longer than 280 nm, reaching zero around 330 nm, therefore UV-B and UV-A can reach Earth's surface and interact with plants [251]. However, UV harmfulness declines in a similar way, as UV-A cannot be absorbed by DNA and it is thus far less damaging for plants [252]. As a result, for a long time, the effects of UV-A on plant physiology had been underestimated and most studies have focused primarily on UV-C and subordinately on UV-B.…”

Stilbenes are a small family of polyphenolic secondary metabolites that can be found in several distantly related plant species. These compounds act as phytoalexins, playing a crucial role in plant defense against phytopathogens, as well as being involved in the adaptation of plants to abiotic environmental factors. Among stilbenes, trans-resveratrol is certainly the most popular and extensively studied for its health properties. In recent years, an increasing number of stilbene compounds were subjected to investigations concerning their bioactivity. This review presents the most updated knowledge of the stilbene biosynthetic pathway, also focusing on the role of several environmental factors in eliciting stilbenes biosynthesis. The effects of ultraviolet radiation, visible light, ultrasonication, mechanical stress, salt stress, drought, temperature, ozone, and biotic stress are reviewed in the context of enhancing stilbene biosynthesis, both in planta and in plant cell and organ cultures. This knowledge may shed some light on stilbene biological roles and represents a useful tool to increase the accumulation of these valuable compounds.

“…Treatment of grapevine cell cultures with the DNA demethylation agent 5-azacytosine and the subsequent analysis of STS DNA methylation and transcription levels revealed that the higher level of cytosine DNA methylation within particular STS genes, the lower level of resveratrol was detected in the cell cultures (Kiselev et al 2013c;Tyunin et al 2013). Subsequently, it has been shown that UV-C-and SA-induced accumulation of stilbenes and transcription of STS genes were coupled to a reduction in the cytosine DNA methylation of these STS genes (Kiselev et al 2015;Tyunin and Kiselev 2016). The data suggest that epigenetic mechanisms might directly or indirectly contribute to the stress-induced activation of stilbene biosynthesis.…”

Main conclusion This review analyzes the advances in understanding the natural signaling pathways and environmental factors regulating stilbene biosynthesis. We also discuss the studies reporting on stilbene content and repertoire in plants.Stilbenes, including the most-studied stilbene resveratrol, are a family of phenolic plant secondary metabolites that have been the subject of intensive research due to their valuable pharmaceutical effects and contribution to plant disease resistance. Understanding the natural mechanisms regulating stilbene biosynthesis in plants could be useful for both the development of new plant protection strategies and for commercial stilbene production. In this review, we focus on the environmental factors and cell signaling pathways regulating stilbene biosynthesis in plants and make a comparison with the regulation of flavonoid biosynthesis. This review also analyzes the recent data on stilbene biosynthetic genes and summarizes the available studies reporting on both stilbene content and stilbene composition in different plant families.

“…Ultraviolet irradiation C (UV-C) is widely known as abiotic elicitor due to its germicidal action in grapes especially in the control of fungal contamination (SCHUMPP et al, 2012, TYUNIN andKISELEV, 2016). This technology can also stimulate the secondary metabolism of plants, favoring the production of defense chemicals without leaving residues that could be a risk to human health (MARTI et al, 2014;PINTO et al, 2016;50 SHEN et al, 2013).…”

“…Considering that the use of UV-C radiation can stimulate the production of bioactive compounds (TYUNIN; KISELEV, 2016), and that one of the major forms of grape consumption in Brazil is through juice (IBRAVIN, 2015), the importance of evaluating the physical and chemical parameters resulting from the application of this technology to grapes is justified.…”

-Grape juice has been widely studied due to the presence of phenolic compounds and its beneficial effects on human health. Ultraviolet irradiation C (UV-C) can increase the content of phenolic compounds and anthocyanins and contribute to sensory acceptability. The aim of this study was to evaluate the effect of different doses of ultraviolet irradiation C (UV-C) on 'Trebbiano', 'Niagara Branca', 'Isabel' and 'Cabernet Sauvignon' grapes, as well as effect of the storage period. Juices were elaborated and evaluated for physicochemical analyses, and for the sensorial analysis in irradiated samples. In 'Niagara Branca' and 'Trebbiano' cultivars, storage and irradiation promoted few physicochemical alterations, and sensorially, irradiation reduced the intensity of flavor and color attributes. In juices from 'Isabel' and 'Cabernet Sauvignon' cultivars, the storage period led to the concentration of sugars and irradiation influenced physicochemical parameters and increased the intensity of aroma attribute at dose of 2 kJ m -2 . Thus, UV-C irradiation contributes little for the improvement of white grape juices; however, it favors some sensory attributes in red grape juice, requiring further studies to elucidate the influence of UV-C irradiation on the phenolic and volatile composition of grape juice.

COMPOSIÇÃO FÍSICO-QUÍMICA E ANÁLISE SENSORIAL DO SUCO INTEGRAL DE UVAS IRRADIADAS COM LUZ ULTRAVIOLETA DO TIPO CRESUMO -O suco de uva vem sendo amplamente estudado pela presença dos compostos fenólicos e seu efeito benéfico para saúde humana. A irradiação ultravioleta do tipo C (UV-C) pode aumentar compostos fenólicos, antociânicos e contribuir com a aceitabilidade sensorial. Este trabalho teve como objetivo avaliar no suco o efeito da aplicação de diferentes doses de irradiação ultravioleta do tipo C (UV-C) sobre as uvas 'Trebbiano', 'Niágara Branca', 'Isabel' e 'Cabernet Sauvignon', bem como o efeito do período de armazenamento. Os sucos foram elaborados e avaliados quanto às análises físico-químicas, e quanto à análise sensorial em amostras irradiadas. Nos sucos das cultivares 'Niágara Branca' e 'Trebbiano', o armazenamento e a irradiação promoveram poucas alterações físico-químicas, e sensorialmente a irradiação reduziu a intensidade dos atributos sabor e cor. Nos sucos das cultivares tintas 'Isabel' e 'Cabernet Sauvignon', o armazenamento levou à concentração de açúcares e a irradiação influenciou tanto os parâmetros físico-químicos quanto favoreceu o aumento da intensidade do atributo aroma na dose de 2 kJ m -2 . Sendo assim, a irradiação UV-C pouco contribui para a melhoria dos sucos de uvas brancas, no entanto, favorece alguns atributos sensoriais nos sucos de uvas tintas, sendo necessários estudos mais amplos para elucidar a influência da irradiação UV-C na composição fenólica e volátil. Termos para indexação: Vitis labrusca, Vitis vinifera, elicitor abiótico, pós-colheita, polifenóis totais, test...
