“…Various postharvest preservation technologies such as edible coating and cold storage have been reported to maintain the postharvest life of fruit and vegetable. Recently, the edible coating such as melatonin, chitosan, MCP, oxalic acid, acetylsalicylic acid and salicylic acid has been extensively studied for maintenance of postharvest life (Orabi et al ., 2018; Yousuf et al ., 2018; de Oliveira et al ., 2020; Liu et al ., 2020). The coating produces semipermeable protective barrier onto the epicarp of the fruit and reduces the quality losses by delaying physicochemical changes (Riva et al ., 2020).…”

Tomato is a climacteric fruit susceptible to rapid softening and ripening after harvest. In this study, the changes of physicochemical characters, cell wall‐degrading enzymes, cell wall compositions and ethylene production of ‘Hisar Arun’ and ‘BSS‐488’ tomato fruits were investigated under the influence of salicylic acid treatment. Salicylic acid treatment effectively delayed firmness decline and increase in PLW, TSS and lycopene content. The treated fruits maintained the integrity of cell wall composition by delay in increase in activities of cell wall‐degrading enzymes (pectin methylesterase, polygalacturonase and cellulose) and cell wall components (cellulose, hemicellulose, lignin and pectin) decline. Moreover, salicylic acid treatments significantly suppress expression level of ethylene‐producing genes (ACO1 and ACS2) and inhibited ethylene production during storage. Overall, the salicylic acid‐induced delay in the ripening process occurs via the strong inhibition of ethylene biosynthesis, lowered cell wall‐degrading enzyme activities and slowed cell wall degradation.

“…The softening is the leading factor which leads to rapid deterioration of fruit such as apricot. The increased softening enzymes activity including CS, PME, and PG during senescence catalyze the depolymerization and degradation of cell wall pectin (Liu et al, 2020). activities.…”

The effect of gum arabic (GA) coating was studied on apricot fruit at 20 ± 1°C for 8 days. GA coating substantially reduced weight loss, disease incidence, malondialdehyde concentration, and hydrogen peroxide compared to the control. GA coating resulted in significantly higher total phenols, ascorbic acid, and antioxidant activity in contrast to the control. GA coating also suppressed cellulase, pectin methylesterase, and polygalacturonase activity in contrast to the non-coated fruit. In addition, GA-coated apricot fruit had substantially higher catalase, peroxidase, ascorbate peroxidase, and superoxide dismutase enzymes activities in contrast with the control.Similarly, GA coating inhibited soluble solids content increase and inhibited the reduction in titratable acidity in coated fruit. The fruit coated with GA coating also had significantly better sensory and overall eating quality compared to the control apricots. In conclusion, GA could be considered an appropriate edible coating for quality conservation of apricots. Practical applicationsApricot is a well renowned and nutrients rich fruit. However, apricot has comparatively short shelf life potential due to its susceptibility to rapid senescence and deterioration under ambient conditions. GA is an eco-friendly and biodegradable coating which is considered relatively cheap as compared with other coating types. In our present work, application of gum arabic [GA (10%)] edible coating maintained significantly higher quality of harvested apricot fruit as compared with the control. The outcomes of the present work are of global significance with respect to apricot industry. So, GA coating could be considered an appropriate edible coating for quality conservation of the harvested apricot fruit.

“…Briefly, melatonin is closely involved in conferring tolerance against endoplasmic reticulum stress [ 15 , 16 ], salt [ 17 , 18 ], pathogens [ 19 , 20 ], high temperatures [ 21 , 22 ], high light stress [ 23 ], and other stresses [ 24 ]. Melatonin also plays roles in plant growth and reproduction, including the synthesis of secondary metabolites [ 25 , 26 ], germination [ 27 ], seed longevity [ 28 ], hormone synthesis [ 29 , 30 ], fruit yield [ 31 ], and other processes [ 32 ].…”

We investigated the relationship between the blue-light photoreceptor cryptochrome (CRY) and melatonin biosynthesis by generating RNA interference (RNAi) transgenic rice plants that suppress the cryptochrome 1b gene (CRY1b). The resulting CRY1b RNAi rice lines expressed less CRY1b mRNA, but not CRY1a or CRY2 mRNA, suggesting that the suppression is specific to CRY1b. The growth of CRY1b RNAi rice seedlings was enhanced under blue light compared to wild-type growth, providing phenotypic evidence for impaired CRY function. When these CRY1b RNAi rice plants were challenged with cadmium to induce melatonin, wild-type plants produced 100 ng/g fresh weight (FW) melatonin, whereas CRY1b RNAi lines produced 60 ng/g FW melatonin on average, indicating that melatonin biosynthesis requires the CRY photoreceptor. Due to possible feedback regulation, the expression of melatonin biosynthesis genes such as T5H, SNAT1, SNAT2, and COMT was elevated in the CRY1b RNAi lines compared to the wild-type plants. In addition, laminar angles decreased in the CRY1b RNAi lines via the suppression of brassinosteroid (BR) biosynthesis genes such as DWARF. The main cause of the BR decrease in the CRY1b RNAi lines seems to be the suppression of CRY rather than decreased melatonin because the melatonin decrease suppressed DWARF4 rather than DWARF.
