Melatonin and its relationship to plant hormones

Annals of Botany, Journal Year: 2017, Volume and Issue: 121(2), P. 195 - 207

Published: Aug. 17, 2017

Plant melatonin appears to be a multi-regulatory molecule, similar those observed in animals, with many specific functions plant physiology. In recent years, the number of studies on plants has increased significantly. One most studied actions is its effect biotic and abiotic stress, such as that produced by drought, extreme temperatures, salinity, chemical pollution UV radiation, among others.

Delay of Postharvest Browning in Litchi Fruit by Melatonin via the Enhancing of Antioxidative Processes and Oxidation Repair

Journal of Agricultural and Food Chemistry, Journal Year: 2018, Volume and Issue: 66(28), P. 7475 - 7484

Melatonin acts as a crucial signaling and antioxidant molecule with multiple physiological functions in organisms. To explore effects of exogenous melatonin on postharvest browning its possible mechanisms litchi fruit, 'Ziniangxi' fruits were treated an aqueous solution at 0.4 mM then stored 25 °C for 8 days. The results revealed that strongly suppressed pericarp delayed discoloration during storage. treatment reduced relative membrane-leakage rate inhibited the generation superoxide radicals (O2-·), hydrogen peroxide (H2O2), malondialdehyde (MDA). markedly promoted accumulation endogenous melatonin; loss total phenolics, flavonoids, anthocyanins; enhanced activities enzymes, including dismutase (SOD, EC 1.15.1.1), catalase (CAT, 1.11.1.6), ascorbate peroxidase (APX, 1.11.1.11), glutathione reductase (GR, 1.6.4.2). By contrast, browning-related enzymes polyphenoloxidase (PPO, 1.10.3.1) (POD, 1.11.1.7) reduced. In addition, up-regulated expression four genes encoding repair oxidized proteins, LcMsrA1, LcMsrA2, LcMsrB1, LcMsB2. These findings indicate delay senescence by harvested fruit could be attributed to maintenance redox homeostasis improvement capacity modulation oxidatively damaged proteins.

Melatonin Improves Drought Stress Tolerance of Tomato by Modulating Plant Growth, Root Architecture, Photosynthesis, and Antioxidant Defense System

Antioxidants, Journal Year: 2022, Volume and Issue: 11(2), P. 309 - 309

Published: Feb. 3, 2022

Tomato is an important vegetable that highly sensitive to drought (DR) stress which impairs the development of tomato seedlings. Recently, melatonin (ME) has emerged as a nontoxic, regulatory biomolecule regulates plant growth and enhances DR tolerance mechanism in plants. The present study was conducted examine defensive role ME photosynthesis, root architecture, antioxidant enzymes' activities seedlings subjected stress. Our results indicated strongly suppressed biomass production, inhibited negatively affected morphology, reduced photosynthetic pigments Per contra, soluble sugars, proline, ROS (reactive oxygen species) were suggested be improved under Conversely, (100 µM) pretreatment detrimental-effect by restoring chlorophyll content, gas exchange parameters attributes compared with DR-group only. Moreover, supplementation also mitigated enzymes [APX (ascorbate peroxidase), CAT (catalase), DHAR (dehydroascorbate reductase), GST (glutathione S-transferase), GR MDHAR (monodehydroascorbate POD (peroxidase), SOD (superoxide dismutase)], non-enzymatic [AsA (ascorbate), DHA (dehydroascorbic acid), GSH (glutathione), GSSG, (oxidized glutathione)] activities, oxidative damage [EL (electrolyte leakage), H2O2 (hydrogen peroxide), MDA (malondialdehyde), O2•- ion)] osmoregulation (soluble sugars proline) seedlings, regulating gene expression for SOD, CAT, APX, GR, POD, GST, DHAR, MDHAR. These findings determine could efficiently improve growth, characteristics, leaf photosynthesis machinery thereby increasing seedlings' adaptability
