“…Our results showed that endogenous melatonin decreased during fruit ripening in sweet cherry. This result is in accordance with those of Tijero et al [41], who concluded that melatonin played an inhibitory role during sweet cherry ripening and has a delicate hormonal balance with abscisic acid, salicylic acid, and jasmonic acid [41]. Zhao et al [35] found that the melatonin content in stage II of fruit development was higher than that in stages I and Ш.…”

“…Based on the above results, it seems that melatonin has a positive effect on different fruits during maturation by mediating metabolism, including glycometabolism and flavonoid biosynthesis. However, Tijero et al [41] found that exogenous melatonin treatment delayed anthocyanin accumulation, thus confirming an inhibitory regulatory role for melatonin in fruit ripening. Therefore, we infer that melatonin may modulate fruit ripening in different fruits depending on its concentration, application time, etc.…”

“…In recent years, studies on melatonin have focused on its exogenous application to improve plant tolerance to various abiotic and biotic stresses or maintain fruit quality postharvest. However, little is known about the putative role of melatonin in sweet cherry fruit development (but see Zhao et al [35] and Tijero et al [41]). Our results showed that endogenous melatonin decreased during fruit ripening in sweet cherry.…”

Although the effects of melatonin on plant abiotic and biotic stress resistance have been explored in recent decades, the accumulation of endogenous melatonin in plants and its influence on fruit quality remains unclear. In the present study, melatonin accumulation levels and the expression profiles of five synthesis genes were investigated during fruit and leaf development in sweet cherry (Prunus avium L.). Melatonin was strongly accumulated in young fruits and leaves, then decreased steadily with maturation. Transcript levels of PacTDC and PacSNAT were highly correlated with melatonin content in both fruit and leaves, indicating their importance in melatonin accumulation. Furthermore, application of 50 and 100 μmol·L−1 of melatonin to leaves had a greater influence on fruit quality than treatments applied to fruits, by significantly improving fruit weight, soluble solids content, and phenolic content including total phenols, flavanols, total anthocyanins, and ascorbic acid. Meanwhile, melatonin application promoted the antioxidant capacity of fruit assayed by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azinobis (3-ethylben zothiazoline-6-sulfonic acid) (ABTS), and ferric reducing antioxidant power (FRAP). These results provide insights into the physiological and molecular mechanisms underlying melatonin metabolism of sweet cherry.

“…A fruit tissue-specific behavior of two of the major phytohormones related with plant-microbe interactions, JA and SA, was observed in cherry fruits during fruit development in a commercial tree orchard. Previous studies on sweet cherry development have shown marked variations in different hormone levels during fruit development, showing a substantial increase of ABA, and an important decrease in JA and SA contents in whole fruits (Teribia et al, 2016;Tijero et al, 2016Tijero et al, , 2019). However, these previous studies did not focus on the role that specific fruit tissues may have in fruit development, despite, as shown here, the differentiation between tissues may provide important hints toward better understanding the physiology and biochemistry of fruit ripening.…”

“…Plant immune responses have been extensively studied, and the role of specific phytohormones like salicylic acid (SA), jasmonic acid (JA), ABA, or ethylene has been described in detail in previous studies using model plants (reviewed by Pieterse et al, 2012). In addition, the role of these hormones in physiological processes like ripening of non-climacteric fruits is already well-known (Leng et al, 2014;Tijero et al, 2019). However, it remains unclear how the interactions between these hormones and ripening may affect fruit specific immune responses to pathogens and, eventually, fruit susceptibility to fruit decay, most particularly in fruits of non-model plants.…”

Sweet cherry is an important non-climacteric fruit with a high commercial interest, but exploitation of sweet cherry trees (Prunus avium L.) in orchards is usually subject to important economic losses due to fruit decay by pathogenic fungi and other microorganisms. Sweet cherries development and ripening are characterized by profound physiological changes in the fruit, among which the phytohormone abscisic acid (ABA) plays a pivotal role. In addition, sweet cherries are usually affected by fruit decay pathogens, and the role of other stress-related hormones such as jasmonic acid (JA) and salicylic acid (SA) may also be of paramount importance, not only from a developmental point of view, but also from a fruit-microbe interaction perspective. Here, a tissue-specific hormone quantification by LC-MS/MS, including the contents of JA, SA, and ABA, in the fruit exocarp and mesocarp of sweet cherries during fruit development from trees growing in a commercial orchard was carried out. Additionally, this study was complemented with the characterization of the culturable epiphytic and endophytic microbial communities of sweet cherries at various stages of fruit development and during cracking lesion formation. Our results revealed a completely differential behavior of phytohormones between both tissues (the exocarp and mesocarp), with a more dynamic exocarp in front of a more stable mesocarp, and with marked variations during fruit development. Microbial epiphytic community was mainly composed by yeasts, although rot-causing fungi like Alternaria spp. were always also present throughout fruit development. Endophytic colonization was poor, but it increased throughout fruit development. Furthermore, when the exocarp was naturally disrupted in sweet cherries suffering from cracking, the colonization by Alternaria spp. markedly increased. Altogether, results suggest that the fruit exocarp and mesocarp are very dynamic tissues in which endogenous phytohormones not only modulate fruit development and ripening but also fruit-microbe interactions.

BACKGROUND: Blueberry is considered as a 'functional food' because it contains bioactive compounds such as flavonoids, phenolic acids, tannins and anthocyanins. The blueberry is one of the most consumed berries in the world and is highly appreciated by consumers because of its unique taste and sensory properties. Fresh blueberries decay rapidly because of mould and water loss. To preserve the qualitative and nutraceutical traits of fresh highbush blueberries during storage, the efficacy of 1 mM melatonin treatment was investigated at 5 °C for 3 weeks. RESULTS:The results demonstrated that melatonin treatment reduced weight loss and delayed postharvest ripening. Compared to the control, melatonin treatment induced an overproduction of polyphenols, flavonoids, anthocyanins and ascorbic acid, consequently increasing antioxidant activity. The enzymatic antioxidant system was also affected by the treatment. An increase in the activity of catalase, superoxide dismutase and ascorbate peroxidase was observed in treated fruit compared to that in control fruit. Enzymatic browning, controlled by assaying the content of malondialdehyde and hydrogen peroxide, polyphenol oxidase, guaiacol peroxidase and lipoxygenase activities, appeared to slow down under melatonin treatment.CONCLUSION: Melatonin coating is a valid tool for delaying the perishability and qualitative decay of highbush blueberry fruit during cold storage. Furthermore, this treatment increases the production of secondary metabolites such as polyphenols, flavonoids, anthocyanins and ascorbic acid, improving the nutraceutical traits of this fruit during storage. Melatonin treatment can be considered as an environmentally sustainable, non-harmful-to-human-health alternative for the postharvest preservation of highbush blueberry fruit.
