“…Ethylene is well known for its role in the regulation of fruit ripening in tomato . Foliar application of exogenous BRs could increase ethylene production in the fruits of tomato (Vardhini and Rao, 2002;Zhu et al, 2015). The decreased and increased production of ethylene in the fruits of d^i m and DWF: OX plants, respectively, suggested that BRs might promote fruit ripening by altering ethylene production in the fruits.…”

“…Significantly, we found that BR levels were closely related to the accumulation of phytoene, phytofluene, b-carotene and lycopene (Table 5). Foliar application of exogenous BRs and ectopic expression of a BZR1-1D transcription factor in BR signalling could enhance carotenoid accumulation in tomato Zhu et al, 2015). Therefore, BRs are actively involved in the regulation of fruit carotenoid metabolism and manipulation of BR biosynthesis, or their signalling is a potential approach to improve fruit quality in tomato.…”

“…Until now, several strategies targeting BR homeostasis have been employed to stimulate plant growth and yield, including exogenous application of BR analogues, chemical inhibitors of BR biosynthe-sis and genetic manipulation of BR biosynthesis or signalling (Vriet et al, 2012). There has been increasing evidence that exogenous application of BR analogues could promote whilst inhibition of BR biosynthesis by the chemical inhibitor impairs plant growth, CO 2 assimilation and fruit carotenoid accumulation (Wu et al, 2008;Xia et al, 2009;Yu et al, 2004;Zhu et al, 2015). BRs are also capable of enhancing plant tolerance/resistance to a wide range of biotic and abiotic stresses, such as drought, salinity, heat, cold, virus infection and pathogen attack (Divi and Krishna, 2009;Xia et al, 2015).…”

SummaryBrassinosteroids (BRs) play a critical role in plant growth, development and stress response; however, genetic evidence for the BR-mediated integrated regulation of plant growth still remains elusive in crop species. Here, we clarified the function of DWARF (DWF), the key BR biosynthetic gene in tomato, in the regulation of plant growth and architecture, phytohormone homeostasis and fruit development by comparing wild type, d^i m , a weak allele mutant impaired in DWF, and DWF-overexpressing plants in tomato. Results showed that increases in DWF transcripts and endogenous BR level resulted in improved germination, lateral root development, CO 2 assimilation and eventually plant growth as characterized by slender and compact plant architecture. However, an increase in DWF transcript down-regulated the accumulation of gibberellin, which was associated with decreases in leaf size and thickness. BRs positively regulated lateral bud outgrowth, which was associated with decreased transcript of Aux/IAA3, and the ethylene-dependent petiole bending and fruit ripening. Notably, overexpression of DWF did not significantly alter fruit yield per plant; however, increases by 57.4% and 95.3% might be estimated in fruit yield per square metre in two transgenic lines due to their compact architecture. Significantly, BR level was positively related with the carotenoid accumulation in the fruits. Taken together, our results demonstrate that BRs are actively involved in the regulation of multiple developmental processes relating to agronomical important traits.

“…However, with the exogenous application of brassinosteroid, there was reduction of the vitamin C content compared to control, at field assay to white fruits (20.71%), pink fruits (34.03%) and red fruits (26.09%) (Figure 2), while to postharvest assay white fruits with brassinosteroid treatment showed a 31.47% increase in vitamin C content compared to control. Similarly, in tomato fruits, considered a model of climacteric ripening, Zhu et al (2015) observed an increase in ascorbic acid in fruits treated with brassinosteroid in the initial storage period, relating the brassinosteroid to the fruit quality maintenance. However, ethylene treatment showed that in red fruit, vitamin C content increased 20.66% compared to control in post-harvest assay (Figure 2).…”

-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 ...

“…In addition, regarding cv. MicroTom, this cultivar is a stunt brassinosteroid-deficient mutant (Martí et al, 2006), and the inhibition of brassinosteroid biosynthesis delays ripening and ethylene production in tomato fruit (Zhu et al, 2015). Therefore, the genetic background of MicroTom might alter the metabolic responses during fruit ripening.…”
