Melatonin (N-acetyl-5-methoxytryptamine) has been detected in a number of plant species. Indeed, there exists evidence that this classically-considered animal indole is actually both synthesized in and taken up by plants. Among the actions that melatonin may carry out in plant tissues, its role as an antioxidant or growth promoter is most strongly supported by the experimental evidence. Other suggested functional implications include the co-ordination of photoperiodic responses and regulation…

Phytomelatonin: A Review
TLDR
It is supposed that melatonin could be used in agricultural practice to enhance the stress-tolerance and productivity of plants.
Phytomelatonin: Discovery, Content, and Role in Plants
TLDR
Its ability to strengthen plants subjected to abiotic stress such as drought, cold, heat, salinity, chemical pollutants, herbicides, and UV radiation makes melatonin an interesting candidate for use as a natural biostimulating substance for treating field crops.
Functional roles of melatonin in plants, and perspectives in nutritional and agricultural science.
TLDR
Evidence indicates that melatonin has an ability to increase the production of crops and may involve the roles of melatonin in preservation of chlorophyll, promotion of photosynthesis, and stimulation of root development.
Functions of melatonin in plants: a review
TLDR
The multiple changes in gene expression caused by melatonin point to its role as a multiregulatory molecule capable of coordinating many aspects of plant development, suggesting that melatonin is an excellent prospect for crop improvement.
Melatonin as an Endogenous Plant Regulatory Signal: Debates and Perspectives
  • W. Park
  • Biology
    Journal of Plant Biology

TLDR
Current knowledge regarding plant melatonin is reviewed and its implications and problems are discussed.
Melatonin : Another Phytohormone ?
TLDR
The criteria are discussed which have to be fulfilled before melatonin might be classified as a phytohormone, and the determination of freely movable melatonin and its movements within the organism are determined.
Phytomelatonin: Assisting Plants to Survive and Thrive
TLDR
This review summarizes the advances that have been made in terms of the identified functions of melatonin in plants and calls for scientists to join the endeavor of clarifying the function of this phylogenetically-ancient molecule in plants, particularly in reference to the mechanisms by which melatonin mediates its multiple actions.

The Physiological Function of Melatonin in Plants
TLDR
The common biosynthetic pathways shared by the auxin, indole-3-acetic, and melatonin, which suggest a possible coordinated regulation in plants, are presented.
Melatonin: A potential regulator of plant growth and development?
TLDR
There is no known specific role for melatonin in plant physiology, but growing information describing melatonin control of physiological processes in mammals, yeast, and bacteria, including diurnal responses, detoxification of free radicals, and environmental adaptations.
Melatonin in plants.
TLDR
Because physiologic concentrations of melatonin in the blood are known to correlate with the total antioxidant capacity of the serum, consuming food-stuffs containing melatonin may be helpful in lowering oxidative stress.
Melatonin acts as a growth‐stimulating compound in some monocot species
TLDR
The results point to the co‐existence of auxin and melatonin in tissues and raises the possibility of their co‐participation in some physiological actions as auxinic hormones in plants.
Melatonin: a growth-stimulating compound present in lupin tissues
TLDR
The data presented in this study demonstrate that melatonin plays a physiological role in plant tissues and is seen to be a molecule that promotes vegetative growth in etiolated Lupinus albus L. hypocotyls, in a similar way to IAA.
Melatonin stimulates the expansion of etiolated lupin cotyledons
TLDR
The data presented in this study demonstrate that melatonin stimulates the expansion of etiolated cotyledons of lupin (Lupinus albus L.) to a similar extent to that observed for IAA but less than in the case of kinetin.
Protective effect of melatonin against chlorophyll degradation during the senescence of barley leaves
TLDR
Of the phytohormones, kinetin, and melatonin combinations assayed, 1 mm melatonin presented the best protection against senescence, and the possible physiological implications of this newly revealed action of melatonin in foliarsenescence are discussed.
Quantification of melatonin in phototrophic organisms
TLDR
The demonstrated methods based on HPLC purification and subsequent quantification by ELISA and HPLC‐PD allow highly sensitive melatonin determinations in diverse photoautotrophic organisms with a low risk of overestimations by false‐positive results.
Melatonin in Plants – Focus on a Vertebrate Night Hormone with Cytoprotective Properties
TLDR
High amounts found in a number of well-designed studies indicate that cytoprotective properties known from animals may play a role in plants, too, and in dry seeds, free radicals cannot be detoxified enzymatically, therefore, melatonin’s scavenging properties could be of biological value and contribute to antioxidative protection.
