The presence of melatonin in plants is universal. Evidence has confirmed that a major portion of the melatonin is synthesized by plants themselves even though a homologue of the classic arylalkylamine N-acetyltransferase (AANAT) has not been identified as yet in plants. Thus, the serotonin N-acetylating enzyme in plants may differ greatly from the animal AANAT with regard to sequence and structure. This would imply multiple evolutionary origins of enzymes with these catalytic properties. A…

Functions of melatonin in plants: a review

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: A Multifunctional Factor in Plants

The biosynthesis pathway, growth and development regulation, and the environment stress response ofmelatonin in plants are summarized and future research directions and priorities of melatonin in animals and plants are speculated.

The content of melatonin in plant-derived foods and the factors that influence melatonin levels are summarized to provide new ideas on enhancement and consuming foods containing higher concentrations of tryptophan and melatonin is suggested.

Agricultural Crops

Melatonin is an indoleamine present in animals and other organisms. Its main function in animals where it acts as a hormone regulating circadian rhythms related processes is well established. It was

Melatonin: Current Status and Future Perspectives in Plant Science

This review has identified many new aspects where melatonin may have possible roles in plants, for example, its function in improving the storage life and quality of fruits and vegetables, its role in vascular reconnection during the grafting process and nutrient uptake from roots by modifying root architecture.

Phytomelatonin: An overview of the importance and mediating functions of melatonin against environmental stresses.

Melatonin is a natural bio-stimulant that creates resistance in field crops against various abiotic stress, including heat, chemical pollutants, cold, drought, salinity, and harmful ultra-violet radiation.

Phytomelatonin, an Interesting Tool for Agricultural Crops

Plant melatonin appears to have developed a type of hormonal function, similar to that observed for other plant hormones, such as auxin, to induce growth in stems and stimulate rooting and to delay senescence by protecting photosynthetic systems and processes.

This issue of the Journal of Experimental Botany reviews, mainly from an evolutionary point of view, the occurrence and functions of melatonin in phototrophs, and the place that melatonin deserves in the network of phytohormones.

Phytomelatonin: Discovery, Content, and Role in Plants

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.

Melatonin and Phytomelatonin: Chemistry, Biosynthesis, Metabolism, Distribution and Bioactivity in Plants and Animals—An Overview

The biosynthetic pathway characteristics of animal and plant cells have been compared, and the main differences between the two systems highlighted and the potential pharmacological and biostimulant benefits derived from the administration of exogenous melatonin on animals or plants via the intake of dietary supplements or the application of biostIMulant formulation have been largely discussed.



Melatonin in plants.

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.

Distribution of melatonin in different zones of lupin and barley plants at different ages in the presence and absence of light.

Perhaps for the first time in plants, liquid chromatography with time-of-flight/mass spectrometry with fluorescence detection for melatonin quantification is used and the distribution of this compound is described, allowing it to be described in different organs and zones in plants.

Phytomelatonin: a review.

A detailed summary of the investigations that have been performed to date in the plant melatonin (phytomelatonin) field is presented to bring the reader up to date on what is known about melatonin in plants.

Chemical stress by different agents affects the melatonin content of barley roots

The data establish, for first time, that the chemical‐stress agents assayed can induce the biosynthesis of melatonin in barley roots and produce a significant increase in their melatonin content.

The Physiological Function of Melatonin in Plants

The common biosynthetic pathways shared by the auxin, indole-3-acetic, and melatonin, which suggest a possible coordinated regulation in plants, are presented.

The changing biological roles of melatonin during evolution: from an antioxidant to signals of darkness, sexual selection and fitness

The changing biological roles of melatonin seem to have evolved from its primary function as an antioxidant, which may indicate senescence in terms of a bio‐clock in many organisms.
