“…Plants have evolved survival mechanisms to eliminate the overproduction of ROS induced by UV irradiation, including mechanisms to modulate the metabolism of carotenoids and flavonoids, and to activate antioxidant defences (Li et al , 1993; Gao and Zhang, 2008; Liu et al , 2011; Tossi et al , 2011). In plants, carotenoids are the essential group of pigments responsible for quenching the ROS (singlet oxygen, etc.)…”

Previous pharmacological results confirmed that haem oxygenase-1 (HO-1) is involved in protection of cells against ultraviolet (UV)-induced oxidative damage in soybean [Glycine max (L.) Merr.] seedlings, but there remains a lack of genetic evidence. In this study, the link between Arabidopsis thaliana HO-1 (HY1) and UV-C tolerance was investigated at the genetic and molecular levels. The maximum inducible expression of HY1 in wild-type Arabidopsis was observed following UV-C irradiation. UV-C sensitivity was not observed in ho2, ho3, and ho4 single and double mutants. However, the HY1 mutant exhibited UV-C hypersensitivity, consistent with the observed decreases in chlorophyll content, and carotenoid and flavonoid metabolism, as well as the down-regulation of antioxidant defences, thereby resulting in severe oxidative damage. The addition of the carbon monoxide donor carbon monoxide-releasing molecule-2 (CORM-2), in particular, and bilirubin (BR), two catalytic by-products of HY1, partially rescued the UV-C hypersensitivity, and other responses appeared in the hy1 mutant. Transcription factors involved in the synthesis of flavonoid or UV responses were induced by UV-C, but reduced in the hy1 mutant. Overall, the findings showed that mutation of HY1 triggered UV-C hypersensitivity, by impairing carotenoid and flavonoid synthesis and antioxidant defences.

“…Comparison of the transcript profiles of skin and pulp from control and treated grapes revealed tissue-specific gene-expression patterns, the skin tissues being more reactive to treatment than pulp. In another work, DNA microarrays were used to investigate the mechanisms induced by post-harvest UV-C irradiation, such as increased defense ability and delayed softening, which improve the shelf life of tomatoes [44]. More recently, a complete study of the mechanisms regulating post-harvest development of onion sprouts was conducted using customdesigned Agilent microarrays [45].…”

“…Treatment with UV-C (180 -280 nm) after harvest has been shown to reduce pathogen growth (Guerrero-Beltrán & Barbosa-Cánovas, 2004) and has been reported to extend the postharvest shelf-life of tomatoes by delayed fruit softening (Liu et al, 2011).…”

Mature green tomatoes (Solanum lycopersicum cv Neang Pich) were exposed to 13.6 kJm-2 UV-C or 0.5 μl l −1 1-MCP or combination of 13.6 kJm-2 UV-C and 0.5 μl l −1 1-MCP, with appropriate untreated controls. After treatment, tomatoes were stored in continuous air containing 0.1 μl l −1 ethylene at 20°C and 100% RH. The untreated fruit ripened significantly faster than all other treatments. UV-C treatment alone was able to delay fruit ripening by up to five days longer compared to untreated fruits whilst the additional of 1-MCP further delayed fruit ripening. UV-C and 1-MCP treatments alone or in combination had significantly slower ethylene production rates throughout the storage period. The fruit treated with the combination of 1-MCP and UV-C was significantly firmer and had higher in total phenolic content compared to the other treatments. However, there was no difference between treatments in SSC/TA ratio, chlorophyll content, lycopene content and total antioxidant activity. These results show that UV-C and 1-MCP treatment delay ripening and improve the quality of tomatoes in the presence of low level ethylene during storage. This new treatment could be used to extend the shelf-life of mature green tomatoes through the supply chain without the use of refrigeration.
