“…Similarly, MT‐treated fruits also showed higher levels of proline. Meanwhile, OAT and P5CS, the enzymes responsible for synthesizing proline, showed an increase after MT treatment while the activity of proline dehydrogenase (PDH) was inhibited (Madebo et al., 2021).…”

Derived from tryptophan, melatonin (MT; N-acetyl-5-methoxytryptamine) is a ubiquitous indoleamine that is widely distributed in species ranging from microorganisms to mammals. It has been associated to play vital roles in the human body like cardiac rhythms, immunological enhancement, and antioxidant activity. In plants, it is a pleiotropic molecule with multiple roles, as it not only performs extensive functions like delaying senescence, growth and development regulation, exerting antioxidant effects, and facilitating adaption of plants to certain biotic and abiotic stress responses but also provides resistance to chilling injury and disease development. This paper reviews the latest progress in the multiple roles of MT in fruits, summarizes the pathways for its biosynthesis, and presents the relation of MT with plant hormones, like auxin, cytokinin, ethylene, gibberellins, abscisic acid, jasmonic, and salicylic acid, and highlights the effect of postharvest application of MT on physiology and quality of fruits, action mechanisms, and safety regulations of MT. Recent trends focus on using alternatives that are safe for postharvest produce and do not have major side effects. MT is a better alternative to hazardous chemicals being commercially used in the postharvest management of fruits and providing future directions for its utilization.

“…Cold storage slows down plant cell metabolism, postpones senescence, and preserves the quality of postharvest horticulture produce by reducing the activity of the majority of enzymes involved in a variety of metabolic activities (Madebo, Hu, et al., 2021). However, even in cold storage, there are chances of injuries if the storage conditions are not maintained properly.…”

“…MT was found to have been involved in the postharvest shelf life of fruits and vegetables stored at cold temperatures by inducing CT through the γ‐aminobutyric acid (GABA) shunt pathway, oxidative pentose phosphate pathway, and regulation of phenolic metabolism (Bhardwaj, Pareek, Saravanan, et al., 2022). Apart from these pathways, some other factors, such as ROS scavenging, improving ascorbate peroxidase (APX), and glutathione reductase, activities also contribute to CT (Madebo, Hu, et al., 2021). The impact of exogenous MT treatment on various physiochemical parameters is discussed below (Table 3).…”

“…The important secondary metabolites and phenolics are present in ample amounts in fruits and vegetables which possess antioxidant characteristics during cold stress conditions, scavenge ROS, and lessen the stress accumulation in fruits and vegetables during the storage period (C. Liu et al., 2018). In kiwifruit, it was observed that flavonoids and flavanol contents increased when treated with MT (Madebo, Hu, et al., 2021). In strawberries at 4 °C, phenolics and total flavonoid content were increased by MT application (C. Liu et al., 2018).…”

The best strategy to extend the shelf life of fresh horticultural produce is to keep it at a low temperature. However, storing fruits and vegetables at a temperature lower than their recommended storage temperature and above the freezing point for a prolonged time leads to the development of chilling injury (CI). Melatonin (MT) being a versatile biological signal has been reported to possess antioxidant properties that aid in mediating stress response and extending the postharvest storage life of horticultural crops. Among CI‐induced mechanisms, MT substantially reduces oxidative stress by elevating the reactive oxygen species scavenging and triggering the phenol accumulation in association with 2, 2‐diphenyl‐1 picryl hydrazyl scavenging activity. Besides, MT increases intracellular energy by maintaining a proper ratio of unsaturated to saturated fatty acid and improving cellular fluidity. Additionally, MT regulates arginine metabolism by maintaining the γ‐aminobutyric acid synthesis. Furthermore, MT encodes the mitogen‐activated protein kinases, and calcium‐dependent protein kinases cascade and acclimate to cold stress by activating C‐repeat binding factors and helps in maintaining postharvest quality. This review reports the recent progress of MT‐induced physiological, biochemical, and molecular mechanisms for enhancing chilling tolerance, which can elevate the marketability and earnings from postharvest horticultural crops.
