“…In tomato, PSY and LCYB are regarded as the key genes responsible for the accumulation of lycopene in tomato fruit. When the transcription of PSY and LCYB is inhibited in tomato, the accumulation of lycopene and b-carotene were significantly inhibited (Bu et al, 2014). Three isoforms of the PSY gene have been reported in watermelon: PSY-A, PSY-B, and PSY-C (Bang et al, 2006).…”

Citrullus lanatus (watermelon) is an excellent daily source of dietary lycopene and β-carotene. To investigate the transcriptional regulation of carotenoid biosynthesis genes relative to lycopene and β-carotene accumulation in watermelon fruit, six watermelon accessions with different flesh colors were examined in this study: white-fleshed PI 459074, pale-yellow-fleshed ‘Cream of Saskatchewan’, light-pink-fleshed PI 482255, orange-yellow-fleshed ‘WM-Clr-1’, and red-fleshed ‘LSW177’ and ‘MSW28’. The expression patterns of eight genes (PSY1, PSY2, PDS, ZDS, CRTISO, LCYB, NCED1, and NCED7) involved in lycopene and β-carotene biosynthesis and biodegradation were analyzed. The results confirmed the accumulation of large quantities of lycopene in red-fleshed ‘LSW177’ and ‘MSW28’, reflecting the elevated expression of PSY1 and the low transcriptional expression of NCED1. The relative expression levels of NCED1 likely play an important role in the color development of the light-pink-fleshed PI 482255, whereas the reduced transcriptional expression of PSY1 and the increased expression of NCED1 appear to be the main factors contributing to the formation of white flesh in the fruit of PI 459074. Low transcriptional expression of PSY1 results in the pale-yellow flesh of the ‘Cream of Saskatchewan’ fruit.

“…Low lycopene content in UV-C treated fruit might be related to the conversion of lycopene to b-carotene by lycopene-b-cyclase, a light-mediated process (Pizarro and Stange 2009). The lower lycopene accumulation in UV-C treated tomatoes coincided with reduced Psy 1, a major gene involved in lycopene synthesis (Bu et al 2014). Although little efforts have been made to examine the effect of harvest maturity on UV-C effectiveness, previous studies have shown that, after the immature green stage, postharvest light treatments are not essential for stimulating lycopene synthesis (Bravo et al 2012).…”

“…There has been a considerable research on the influence of ultraviolet irradiation on nutritional quality. Studies have shown that irradiation significantly affects vitamin content (Charles et al 2016;Jagadeesh et al 2011;Severo et al 2015), phenolics and flavonoids (Castagna et al 2014;Maharaj et al 2014), antioxidant capacity (Bravo et al 2012;Liu et al 2012) as well as carotenoids (Bu et al 2014;Pizarro and Stange 2009) of tomato fruit.…”

Effect of ultraviolet irradiation on postharvest quality and composition of tomatoes: a review

et al. 2017

View full text Add to dashboard Cite

Ultraviolet (UV) irradiation has recently emerged as a possible alternative to currently used postharvest phytosanitary treatments. Research has also highlighted other benefits associated with UV irradiation in postharvest technology. This review presents the effects of UV irradiation on postharvest and nutritional quality of tomatoes. The application of UV irradiation on tomatoes is discussed including its effect on biological (respiration rate, ethylene production and microbial growth), physico-chemical (firmness, colour, total soluble solids and titratable acidity) and nutritional (vitamins, carotenoids, phenolic and antioxidants) quality. UV-treated tomatoes have shown resistance to microbial growth and decay. Although UV irradiation reduces the loss of vitamin C during storage, the loss of vitamin E remains a concern. UV treatments lead to higher antioxidant capacity, flavonoids and phenolic content. UV irradiation significantly reduced carotenoids in certain cultivars. Based on the literature reviewed, the success of UV irradiation treatments is cultivar-dependent. While improved retention of phytochemicals has been reported in UV-C treated fruit, increased losses have been reported in certain cultivars. Research efforts on the development of cultivar-specific UV irradiation protocols are warranted. The effect of harvest maturity and seasonal differences in the efficacy of UV treatments is required to be investigated.

Alternative Strategy on Control of Postharvest Diseases of Mango (Mangifera indica L.) by Use of Low Dose of Ultraviolet-C Irradiation

The demand for clean, safe and sustainable alternative control measures of postharvest diseases of fruit has increased in recent years, and the use of UV-C irradiation is a potential option. This study focused on evaluating UV-C dose effect on in vitro and in vivo development of fungi species and also on postharvest decay on mango cv. Tommy Atkins. The evaluated fungi which cause decay were as follows: Botryosphaeria dothidea, Lasiodiplodia theobromae, Alternaria alternata and Colletotrichum gloeosporioides. Fungus mycelium was exposed to increasing doses of UV-C irradiation: 0 (control), 2.0, 3.0, 5.0, 10.0 and 20 kJ m -2 . L. theobromae and A. alternata received dose up to 59.7 kJ m -2 . Mangos artificially inoculated with B. dothidea were treated with doses of UV-C irradiation: 0.0, 0.5, 1.0, 2.5, 5.0, 7.5 e 10.0 kJ m -2 and stored at 10°C for 15 days and for 2 days at 22°C, observing the rot on daily basis. The trials were conducted in a completely randomized design with six replicates for in vitro tests and four replicates with seven fruit as experimental unit. The in vitro trials demonstrated that even high dose of UV-C (20 kJ m -2 ) was not able to control the fungi development. Nonetheless, low dose of UV-C irradiation at 2.5 kJ m -2 controlled around 70 % of fruit rot severity. Higher doses ([5 kJ m -2 ) caused damage on mango peel increasing the rot severity. Results suggest that, the application of low dose (\3 kJ m -2 ) of UV-C irradiation can contribute to the integrated management of postharvest diseases on mango, and that, the mechanisms of control involved are not directly related to the fungi development.
