ABSTRACT Melatonin ( N ‐acetyl‐5‐methoxytryptamine), a well‐known mammalian hormone, has been having great relevance in the Plant World recent years. Many of its physiological actions plants are leading to possible features agronomic interest, especially those related improvements tolerance stressors and postharvest life fruits vegetables. Thus, through exogenous application melatonin or by modifying endogenous biosynthesis phytomelatonin, some change can be made functional levels tissues their responses. Also, acting respective phytomelatonin enzymes, regulating expression tryptophan decarboxylase TDC ), tryptamine 5‐hydroxylase T5H serotonin ‐acetyltransferase SNAT ‐acetylserotonin O ‐methyltransferase ASMT caffeic acid COMT recently action deacetylases on intermediates offers promising opportunities for improving vegetables marketability. Other regulators/effectors such as different transcription factors, protein kinases, phosphatases, miRNAs, protein–protein interactions, gasotransmitters nitric oxide hydrogen sulfide were also considered an exhaustive vision. interesting aspects role autophagic responses, posttranslational reprogramming protein‐phosphorylation, ubiquitylation, SUMOylation, PARylation, persulfidation, nitrosylation described phytomelatonin‐mediated responses discussed, including relationship several plant hormones, chilling injury fungal decay alleviating. The current data about receptor (CAND2/PMTR1), effect UV‐B light cold storage damage presented discussed. All this focus new preservation quality

Effects of an Exogenous Melatonin Treatment on the Physiological Indexes and Storage Duration of Cut Chrysanthemum Flowers

Horticultural Science and Technology, Journal Year: 2024, Volume and Issue: 42(5), P. 533 - 548

The present study investigated the role of melatonin (MT) in improving storage duration cut chrysanthemum flowers. flowers were exposed to different concentrations MT and stored at 20°C ± 1°C 90% relative humidity. Cut treated with 5 µM had longer durations than those kept water. results demonstrated that significantly enhanced water balance decreased loss. treatment group exhibited a higher fresh weight flower diameter control group. Leaves showed lower malondialdehyde (MDA) contents lipoxygenase (LOX) activity levels Moreover, application antioxidant capacity leaves by upregulating activities key enzymes involved scavenging reactive oxygen species, including superoxide dismutase, peroxidase, catalase. This suggests effectively mitigated oxidative stress cell damage during storage, which may contribute its ability extend shelf life Furthermore, reduced proline content petals These findings suggest improves most likely regulating system
