“…Likewise, in red fruits at field analysis, there was a reduction of 32.51% in the content of phenolic compounds compared to control (Figure 1). However, this result disagrees with Xi et al (2013), which observed increased activity of PAL, phenolic compounds, anthocyanins and antioxidant capacity in grape berries, other non-climacteric fruit, after field brassinosteroid treatment.…”

“…For firmness, we observed the firmness reduction, from 54.36N in green fruits to 9.59N in red fruits, because during the maturation occur changes like solubilization and depolymerization of pectin that causes pulp softening (VILLAREAL et al, 2008). There is hue angle reduction during the maturation of 105.06ºh in green fruits to 26.03ºh in red fruits, demonstrating the increase of light red color in the fruits, mainly by the accumulation of anthocyanins pelargonidin-3-O (Pg3) and cyanidin-3-glucoside (Cy3 glc) (ZHANG et al, 2008) and chlorophyll degradation (VILLARREAL et al, 2010). In addition, there was a trend of increasing soluble solids content, from 6.86°Brix in green fruits to 8.99°Brix in red fruits, and reduction of the total titrated acidity, from 0.68% of citric acid in green fruits to 0.48% of citric acid in red fruits, because the sucrose and polysaccharides degradation of reserve and consumption of organic acids in the Krebs cycle, due to respiration for energy production (VALERO; SERRANO, 2010) (Data not shown).…”

“…According to Xi et al (2013) the phenylpropanoid pathway and the accumulation of phenolic compounds can be stimulated as a physiological response to a stress condition, therefore, the exogenous application of ethylene would have direct effect. Likewise, we can assume that brassinosteroids may be negatively interfering with the phenylpropanoid pathway, whereas ethylene seems to stimulate, increasing the production of phenolic compounds.…”

-In contrast to ripening of climacteric fruits knowledge, non-climacteric fruits ripening still poorly understood. In this sense, strawberry (Fragaria x ananassa L. Duch) is a high commercial crop and has an expressive world production that has been used as a model study. Thus, the aim of this study was to evaluate the effect on physicochemical and phytochemical characteristics of strawberry Cv. Camiño Real, in four maturation stages (green, white, pink and red) after the ethylene (Etephon®) and brassinosteroid (epi-brassinolide) exogenous spray. The evaluations were carried out at application time (field assay) and after 24h (post-harvest assay). Brassinosteroid application tends to reduce phenolic compounds content mainly in the red stage, whereas ethylene treatment tends to increase supposing that while brassinosteroids reduce phenolic compounds acting to fruit conservation, by the reduction of oxidative stress, increasing antioxidant activity, the ethylene act in fruit ripening leading to senescence. However, for vitamin C content while brassinosteroid treatment increases ascorbic acid in postharvest for the white fruit, the ethylene treatment do a dramatically increased in vitamin C content to red fruits, showing that although ethylene and brassinosteroids can affect the vitamin C content, the response can change according to the development stage spray, suggesting that more studies are necessary to understand the hormonal interaction for ascorbic acid production during strawberry ripening.

Efeito do etileno e do brassinoestereoide no amadurecimento do morango após aplicação no campoResumo -Em contraste com o conhecimento sobre a maturação de frutos climatéricos, a maturação de frutos não climatéricos ainda é pouco entendida. Neste sentido, o morangueiro (Fragaria x ananassa) é uma cultura de elevado valor comercial e expressiva produção mundial que vem sendo utilizada como modelo de estudos. Assim, o objetivo deste trabalho foi avaliar o efeito sobre as características físico-químicas e fitoquímicas do morango Cv. Camiño Real, em quatro estádios de maturação (verde, branco, rosa e vermelho), após o spray exógeno de etileno (Etephon®) e brassinoesteroide (epibrassinolide). As avaliações foram realizadas no momento da aplicação (ensaio de campo) e após 24 h (ensaio pós-colheita). A aplicação de brassinoesteroide reduz o conteúdo de compostos fenólicos no estádio vermelho, enquanto o tratamento com etileno aumenta. Assim, supõe-se que, enquanto os brassinoesteroides diminuem a concentração de compostos fenólicos, atuando na conservação dos frutos pela redução do estresse oxidativo e pelo aumento da atividade antioxidante, o etileno age acelerando o amadurecimento do fruto, levando à senescência. No entanto, para o conteúdo de vitamina C, enquanto o tratamento com brassinoesteroide aumenta o ácido ascórbico na pós-colheita em frutos brancos, o tratamento de etileno aumentou dramaticamente o conteúdo de vitamina C ...

“…Similar to stilbene biosynthesis regulation, different hormone signaling pathways (ABA, JA, ET, cytokinin, SA, GA, or BRs) have been shown to influence production of flavonoids (Loreti et al 2008;Jeong et al 2010;Das et al 2012a, b;Ghasemzadeh et al 2012;Xi et al 2013;Degu et al 2016). Among them, ET and GA have been shown to play a negative role in flavonoid biosynthesis (Loreti et al 2008;Jeong et al 2010).…”

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.

“…Several reports have shown that BRs are involved in the development and ripening of fleshy fruit, such as tomato (Vardhini and Rao 2002), mango (Zaharah et al 2012), cucumber (Fu et al 2008) and strawberry (Chai et al 2013). With regard to grapes, exogenous application of BRs significantly promotes berry ripening (Symons et al 2006) and enhances phenolics contents Xi et al 2013b). However, limited information is available on the influence of BRs on PAs biosynthesis during grape berry development.…”

Cabernet Sauvignon' (Vitis vinifera L.) grape berries were treated with 0.4 mg/l 24-epibrassinolide applied once at fruit set ('pea-sized berry' phenological stage) (EBR-T1) or the same concentration EBR applied twice at fruit set and 14 days before véraison (EBR-T2). Berries sprayed with deionized water served as the control. The contents of proanthocyanidins (PAs) in the berry skin and seed, and the expression patterns of structural genes (VvLAR1, VvLAR2, VvANR, and VvANS) and transcription regulator genes (VvMYB5a, VvMYB5b, and VvMYBPA1) of PAs in the berry skin were measured. At berry maturity, total tannins in the skin of EBR-T1-and EBR-T2-treated berries were significant higher than those in control. Monomeric and oligomeric flavan-3-ols showed different levels of promotion by 24-epibrassinolide during berry development. The mRNA levels of the structural genes VvLAR1, VvLAR2, and VvANS and the transcription regulator gene VvMYBPA1 were affected significantly by 24-epibrassinolide treatment, but the effects varied at different stages of berry development. Most of the targets measured showed no significant difference between the EBR-T1 and EBR-T2 treatments. Thus, in general, application of 24-epibrassinolide enhanced PAs biosynthesis in the berry skin.
