“…•− and H 2 O 2 rates in the berries, which resulted in lower repining and senescence during storage [42]; these results are in agreement with some other reports that found that melatonin application significantly lowers the H 2 O 2 rate in stored peach and cassava [43,44]. Moreover, Wang et al [15] observed a decrease in O 2…”

Table grape berries are classified as a perishable crop that deteriorates quickly after harvest. The application of melatonin after harvest was found to be effective for retarding senescence and slowing ripening. In the current study, we tested the influence of two melatonin concentrations (50 and 100 µmol) as a postharvest application on quality, bioactive compounds, and enzyme activities of grape berries cv “Crimson” stored at 0 ± 1 °C and 90% relative humidity (RH) for 35 days. Our results indicated that melatonin application extends the shelf-life of berries by reducing weight loss and maintaining total soluble solids (TSS), titratable acidity (TA), berry adherence strength, and firmness. Melatonin treatment also reduced pectin methyl esterase (PME) and polygalactouranase (PG) enzyme activities compared to the control. Moreover, O2•− and H2O2 rates in berries were reduced by high melatonin concentration. Moreover, peroxidase (POD) and catalase (CAT) enzyme activities were increased by melatonin application. Our findings suggested using melatonin postharvest to increase shelf life and maintain quality attributes during refrigerated storage, which could be advantageous on a large scale.

“…As many plants are whole genome sequenced, and researchers have benefited from the availability of high-quality genomic data to find homologs of these enzymes. SNAT homolog was also reported in other species, including alga laver, cyanobacteria, apple, Arabidopsis, grapevine ( Tripathi et al, 2021 ). Furthermore, genome-wide studies have revealed that presence of these enzymes is diversified, with varied in frequency of existence in different plants.…”

“…Furthermore, ectopic overexpression of MzSNAT5 in Arabidopsis reported increased melatonin concentration and improve drought tolerance. Moreover, when the SNAT production in rice was suppressed, the adverse effects were observed on plant growth, and low melatonin levels ( Tripathi et al, 2021 ). It was certain that low melatonin levels have penalty of increased susceptibility to abiotic stresses and ultimately low yield levels.…”

A pervasive melatonin (N-acetyl-5-methoxytryptamine) reveals a crucial role in stress tolerance and plant development. Melatonin (MT) is a unique molecule with multiple phenotypic expressions and numerous actions within the plants. It has been extensively studied in crop plants under different abiotic stresses such as drought, salinity, heat, cold, and heavy metals. Mainly, MT role is appraised as an antioxidant molecule that deals with oxidative stress by scavenging reactive oxygen species (ROS) and modulating stress related genes. It improves the contents of different antioxidant enzyme activities and thus, regulates the redox hemostasis in crop plants. In this comprehensive review, regulatory effects of melatonin in plants as melatonin biosynthesis, signaling pathway, modulation of stress related genes and physiological role of melatonin under different heavy metal stress have been reviewed in detail. Further, this review has discussed how MT regulates different genes/enzymes to mediate defense responses and overviewed the context of transcriptomics and phenomics followed by the metabolomics pathways in crop plants.

“…This role as a protective agent has been widely studied in many plant species and in multiple stressful situations. Several recent reviews on this topic can be consulted (Moustafa-Farag et al 2020a, c;Pardo-Hernández et al 2020;Sharma et al 2020;Nawaz et al 2020;Ahn et al 2021;Hernández-Ruiz 2021a, 2022;Hoque et al 2021;Tripathi et al 2021;Zhao et al 2021aZhao et al , 2022Giraldo-Acosta et al 2022). Generally, phytomelatonin actions through phytomelatonin receptor (PMTR1), and it appears to activate metabolic, hormonal, and defense responses, providing the plant with greater tolerance against biotic/abiotic stressor (Wei et al 2018a;Wang et al 2021;Yang et al 2021;Li et al 2022).…”

Melatonin (N-acetyl-5-methoxytriptamine) is a novel plant regulatory molecule currently under study. Its role as a biostimulator and protector against abiotic and biotic stressors, through the regulation of the redox network and change in the expression of many elements of primary and secondary metabolism, is of great interest. The possible protective effect of melatonin in mungbean seedlings, previously primed seed treated with the fungicide copper oxychloride, was studied. The effect of melatonin and fungicide in growth of seedlings and photosynthetic pigments, leakage membranes, lipid peroxidation, antioxidant activity, and phytomelatonin content was studied. Also, the effect of exogenous melatonin on endogenous plant hormones indoleacetic acid, gibberellins, cytokinins, abscisic acid, salicylic acid, and jasmonic acid levels, in the absence and presence of fungicide, was analyzed. Melatonin improved growth of roots and aerial parts in the presence of fungicide; chlorophyll and carotenoid contents were protected by melatonin in the presence of melatonin and in melatonin-fungicide co-treatments. Membrane damage due to fungicide was lessened by melatonin. The hormonal profile (auxin, gibberellins, cytokinins, abscisic acid, ethylene precursor, salicylic acid, and jasmonic acid) in roots and leaves was greatly affected by copper fungicide and melatonin treatments. In general, an increasing in plant tolerance response has been detected, proposing melatonin as a natural safener molecule of plants in the presence of copper fungicide.
