“…The application of 1-MCP reduces color index increment and chlorophyll degradation, as also reported by Rodrigo et al [26]. These effects on ripening are temporary because the application of the inhibitor does not necessarily block all ethylene receptors, which, at the cell membrane level, can be newly generated.…”

Mandarin accounts for a significant part of the Colombian citrus fruit production, the postharvest degreening of these products to attain pigmentation being a common practice when they are harvested in the tropics. The endogenous signaling molecules such as methyl jasmonate and ethylene are produced during fruit formation, and they play a key role in postharvest and stress responses. The latter is commonly used to degreen mandarin, which, however, exhibits low sensitivity to this compound. It is therefore important to establish degreening alternatives to ethylene. Thus, the aim of this study was to determine the effect of methyl jasmonate on the degreening of Arrayana mandarin (Citrus reticulata L.). For such purpose, respiration rate, weight loss, color index, total chlorophyll, total soluble solids, firmness and total acidity were determined. The treatments applied were: methyl jasmonate (MeJA) 1 µM 24h, Ethylene (ET) 1000 ppm 20 min, 1-methylcyclopropene (1-MCP) 0.5 µL L -1 2h; and the combinations 1-MCP + MeJA, 1-MCP + ET. Generally obtained with the MeJA and 1-MCP + MeJA treatments, the most significant results took place at 14 days after treatment implementation (DATI) for total titratable acidity, and at 4 DATI for total chlorophyll and color index. The TSS/acid ratio (maturity ratio) became constant since 7 DATI under the MeJA treatment. Thus, the use of MeJA after 1-MCP pretreatment comes to be an interesting degreening option, all the more when considering that these physiological responses have not been reported in previous studies.

“…Over decades, growers and breeding programmes have used the genetic diversity among the Citrus genus to select new cultivars as wells as spontaneous and induced mutations differing in either external or internal fruit quality, in which colouration is one of the most remarkable selection parameters (Kato 2012;Garcia-Lor et al 2013;Rodrigo et al 2013). As carotenoids are the main pigments in mature citrus fruits, a great diversity of carotenoid profiles has been created, which constitute an excellent experimental material to explore the biochemical and molecular bases governing citrus fruit colouration.…”

“…Carotenoids, in addition to the relevant functions in plants (Britton 2008), are also important nutritional components of the human diet, since some of them are precursors of vitamin A and possess beneficial antioxidant capacities, playing then a role in the protection against degenerative and chronic diseases (Berman et al 2014). Due to these relevant functional properties and their importance in the organoleptic quality of citrus fruit, carotenoid content and composition and their metabolic regulation in the peel and pulp of different citrus species and varieties have been extensively studied over decades (reviewed in Kato 2012;Rodrigo et al 2013).…”

“…Citrus fruits are one of most complex sources of carotenoids, with a large diversity of these compounds among the different species and cultivars in terms of types and amounts (Kato et al 2004;Fanciullino et al 2006;Xu et al 2006;Kato 2012;Rodrigo et al 2013). Interestingly, a common feature in mature citrus fruit is that carotenoid concentrations are usually higher in the peel than in the flesh (juice vesicle), and most of the citrus species and varieties display a different carotenoid profile in these tissues, suggesting differential regulation of biosynthesis and accumulation of these pigments in these fruit tissues (Tadeo et al 2008).…”

“…Therefore, taking advantage of the great variability in fruit carotenoid composition among sweet oranges and grapefruits, the main objective of the present study has been to investigate the changes in chromoplast ultrastructure during ripening in relation to the carotenoid complement in fruits of selected varieties from these citrus species. To that end, fruits from the ordinary Navel sweet orange (Citrus sinensis L. Osbeck), with the typical standard orange colouration, which accumulates b,b-xanthophylls, mainly 9-(Z)-violaxanthin, as well as lower amounts of colourless carotenoids and apocarotenoids C 30 (Oberholster et al 2001;Rodrigo et al 2004Rodrigo et al , 2013, were selected and compared with two sweet orange spontaneous mutants, the yellow Pinalate and the red-pulp Cara Cara. Pinalate is a unique mutant with a distinctive pale-yellow colouration in peel and pulp of mature fruit accumulating significant amounts of early linear carotenes: phytoene, phytofluene and f-carotene isomers, while the proportion of b,b-xanthophylls is extremely reduced, implying a blockage at the stage of desaturation of f-carotene (Rodrigo et al 2003).…”

Differentiation of new and characteristic plastid ultrastructures during ripening of citrus fruits in both peel and pulp appears to be strongly correlated with the content and complement of carotenoids. Most of the species of the Citrus genus display a wide range in fruit colouration due to differences in carotenoids; however, how this diversity is related and may contribute to plastid differentiation and ultrastructure is currently unknown. To that end, carotenoid profile and plastid ultrastructure were compared in peel and pulp of three sweet oranges: the ordinary orange-coloured Navel, rich in β,β-xanthophylls, the yellow Pinalate mutant with an elevated content of colourless carotenes and reduced β,β-xanthophylls, and the red-fleshed Cara Cara with high concentration of colourless carotenes and lycopene in the pulp; and two grapefruits: the white Marsh, with low carotenoid content, and the red Star Ruby, accumulating upstream carotenes and lycopene. The most remarkable differences in plastid ultrastructure among varieties were detected in the pulp at full colour, coinciding with major differences in carotenoid composition. Accumulation of lycopene in Cara Cara and Star Ruby pulp was associated with the presence of needle-like crystals in the plastids, while high content of upstream carotenes in Pinalate pulp was related to the development of a novel plastid type with numerous even and round vesicles. The presence of plastoglobuli was linked to phytoene and xanthophyll accumulation, suggesting these structures as the main sites for the accumulation of these pigments. Peel chromoplasts were richer in membranes compared to pulp chromoplasts, reflecting their different biogenesis. In summary, differences in carotenoid composition and accumulation of unusual carotenoids are mirrored by the development of diverse and novel chromoplast types, revealing the plasticity of these organelles to rearrange carotenoids inside different structures to allow massive accumulation and thus contributing to the chemical stability of the carotenoids.

Today's green chemistry technologies open the route to a broader and richer economy for lemons, well beyond the fresh fruit and fruit juice markets. This has important social, environmental, and economic consequences for all lemon‐growing countries and for many industries. Which are the new bioproducts obtainable from lemon and its by‐products? And what are the unforeseen new applications of old bioproducts such as pectin? Following an updated outlook on the global lemon economy, it is shown through selected examples how the lemon bioeconomy might unfold in the course of the next few years (2021–2025).
