“…It has also been shown to protect plants from various biotic and abiotic stresses [12]. Exogenous MT treatment has recently been reported as a successful postharvest treatment to reduce ethylene action, delay postharvest senescence, and improve chilling-injury tolerance in several fruits [13][14][15] by activating the antioxidant system, reducing postharvest deterioration, and maintaining fruit nutritional quality [16]. Moreover, Magri and Petriccione [17] revealed that treating fruits with MT during the pre-storage stage reduces deterioration and increases their antioxidant capacity.…”

Mango (Mangifera indica L.) is one of the most popular tropical fruits grown in Egypt and several other countries, making it a potential export commodity. Excessive deterioration after harvest requires various treatments to maintain fruit quality. We evaluated the treatments effects of melatonin (MT) as an anti-ethylene agent and tragacanth gum (TRG) as an edible coating individually and together (MT–TRG) before storing mangoes at 12 °C for 32 days under 85–90% relative humidity. Compared with control, all treatments were significantly effective in preserving fruit quality. Fruits treated with MT–TRG showed significantly lower decay values, respiration rates, ethylene production, and weight loss than untreated fruits. MT–TRG treatment significantly enhanced fruit quality, thereby maintaining fruit appearance, flesh color, firmness, total soluble solids and phenolic contents, and pectin methyl esterase, polyphenol oxidase, and peroxidase activities during the storage period. We propose 200 µM MT + 1% TRG as a safe postharvest treatment to reduce the deterioration of mangoes and maintain fruit quality.

“…Polyamines (PAs) are also important plant growth regulators in regulating plant growth, the absorption of inorganic ions, and plant resistance Das 2022, Li et al 2022). Increasing evidence showed that PAs enhanced plant tolerance to salt, drought, and chilling stresses (Buffagni et al 2022, Dong et al 2022, Ozmen et al 2022. As one of the PAs, putrescine (Put) is a ubiquitous low-molecular-weight polyamine and contains two amino groups.…”

In the world, salt stress limits wheat growth and production. Salt stress often induces oxidative damage by leading to the accumulation of excess reactive oxygen species (Kapoor and Hasanuzzaman 2020). Fortunately, plants can counteract oxidative damage through the antioxidant system (Soliman et al. 2020). In the antioxidant system, reduced ascorbate (AsA) and reduced glutathione (GSH) are major antioxidants (Mohsin et al. 2020). Their contents can be regulated through their regeneration and biosynthesis (Zhu et al. 2021). l-galactono-1,4-lactone dehydrogenase (GalLDH) and gamma-glutamylcysteine synthetase (γ-ECS) are the key enzymes for the biosynthesis of AsA and GSH, respectively. Ascorbate-glutathione (AsA-GSH) cycle is in charge of their regeneration. In this cycle, ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR), and dehydroascorbate reductase (DHAR) are in charge of their operation (Maslennikova et al. 2022). Through this cycle, plants can not only realise AsA and GSH regeneration but also scavenge hydrogen peroxide (H 2 O 2 ). Therefore, the metabolism of ASC and glutathione in plants played vital roles in counteracting salt stress.
