“…In agreement with this, our results show that MAP is effective in preventing CI in cucumber fruits. Liu et al (2016) previously noted that the postharvest application of methyl jasmonate and nitric oxide inhibits H 2 O 2 accumulation in cucumber fruits and reduces CI. No similar studies were found for LO, but PEx was previously reported by Kahramano glu et al (2018) to reduce CI on pomegranate fruits during storage.…”

The present study was conducted with the aim of increasing storage duration of cucumber fruits by using eco-friendly edible biomaterials and nanotechnology. Hence, the effects of postharvest-applied lemongrass oil (LO) and propolis extract (PEx), alone or in combination with modified atmosphere packaging (MAP), on the weight loss, fruit firmness, sensory index, chilling injury (CI), decay incidence (DI), and soluble solid concentration (SSC) of cucumber fruits were tested. Two different doses (0.2% and 0.5%) of both LO and PEx were tested in present study. Application of LO and PEx was performed by dipping the fruits into the solutions at 21 ± 1 °C for 3 minutes; after drying for 30 minutes, fruits were transferred to a cold room and kept at 4.5 ± 0.5 °C and 95% relative humidity (RH). Studies were continued for 24 days, and quality parameters were measured at 4-day intervals. Two-day shelf-life simulation was also applied to fruits after each interval, and the same quality parameters were observed. Results suggest that the combination of MAP bags with LO or PEx treatment provides better conditions for postharvest storage of cucumbers and that storage duration might be extended to 20 days. Fruits treated with LO or PEx and stored in MAP bags maintained weight and SSC, were firmer, showed lower DI, and expressed lower CI (P < 0.05) throughout storage.

“…Evidence obtained by Aydin and Nalbantoğlu [128] showed that SA pretreatment of Spinacia oleracea leaves inluenced NR activity to induce chilling stress tolerance. A recent study indicated the involvement of JA in NO synthesis that increased CAT activity to scavenge H 2 O 2 , leading to reduced chilling injury in Cucumis sativus [129]. Therefore, it is concluded that NO cross talk with other hormones safeguards the quality of stored fruits and vegetables.…”

Phytohormones - Signaling Mechanisms and Crosstalk in Plant Development and Stress Responses

View full text Add to dashboard Cite

Plants, being sessile, are concurrently exposed to various biotic and abiotic stresses. The perception of stress signals in plants involves a wide spectrum of signal transduction pathways that interact to induce tolerance against adverse environmental conditions. This functional overlapping among various stress signaling cascades also leads to the expression of genes that regulate biosynthesis or action of other hormones. Phytohormonal signals, activated by both developmental and environmental responses, play a crucial role to develop stress tolerance in plants. Nitric oxide (NO) is one of the major players in plant signaling networks. Emerging evidence supports that NO interplays with signaling pathways of auxins, gibberellins, abscisic acid, ethylene, jasmonic acid, brassinosteroids, and other plant hormones to control metabolism, growth, and development in plants. This chapter focuses on the current state of knowledge of cross talk between signaling pathways of NO and phytohormones in plants exposed to various abiotic stresses.

“…Chilling injury and secondary disease symptoms of the fruit surface were evaluated for 30 fruit for each replicate using a subjective scale of visual symptoms described previously (Liu et al, 2016). Chilling injury development was observed during storage at 5°C and secondary disease development was observed at ambient temperature (20°C) following 12 d of cold storage.…”

Chilling stress can cause cellular DNA damage, affecting the faithful transmission of genetic information. Cold acclimation enhances chilling tolerance, but it is not clear that the process of cold adaption involves DNA damage responses, as cold acclimation does not form real chilling stress. Here we showed with cucumber fruit that pre-storage cold acclimation (PsCA) reduces chilling injury and upregulates DNA damage inducible protein1 (CsDDI1), suggesting that the chilling tolerance induced by cold acclimation involves CsDDI1 transcription. Application of nitric oxide (NO), abscisic acid (ABA) or H 2 O 2 biosynthesis inhibitor before PsCA treatment downregulates CsDDI1 and aggravates chilling injury, while H 2 O 2 generation inhibition plus exogenous NO or ABA application before PsCA treatment restores chilling tolerance, but does not restore CsDDI1 expression, suggesting H 2 O 2 plays a crucial role in triggering cold adaption. CsDDI1 overexpression Arabidopsis lines show faster growth, stronger chilling tolerance, lower reactive oxygen species levels, enhanced catalase and superoxide dismutase activities and higher expression of nine other Arabidopsis defense genes under chilling stress, suggesting CsDDI1 strengthens defenses against chilling stress by enhancing antioxidant defense system. Taken together, CsDDI1 positively regulates chilling tolerance induced by cold acclimation in cucumber. In addition, H 2 O 2 is involved in initiation of cold acclimation. While CsDDI1 upregulation requires H 2 O 2 as a key signaling molecule, the upregulation of CsDDI1 activates an antioxidant system to reduce biotoxic accumulation of H 2 O 2 and helps in DNA repair.
