The primary hormone of the vertebrate pineal gland, melatonin, has been identified broadly throughout the tree of life, in animals, plants, and fungi, supporting a deep evolutionary origin for this signaling molecule. However, some key groups have not been studied. Echinoderms, deuterostome animals, are one of these groups. Herein we study the presence of melatonin and enzymes of its pathway in the sea star Echinaster brasiliensis. We demonstrate that E. brasiliensis produces endogenous…

The Effect of Melatonin on Locomotor Behavior and Muscle Physiology in the Sea Cucumber Apostichopus japonicus
TLDR
The results suggest that the sedative effect of melatonin involves some other metabolic pathways, and the reduced locomotor modulator—serotonin, inhibited fatty acid oxidation and disturbed oxidative phosphorylation are potential physiological mechanisms that result in the inhibitory effect ofmelatonin on locomotion in sea cucumbers.
Determination of melatonin in Acyrthosiphon pisum aphids by liquid chromatography-tandem mass spectrometry.
Differences in Small Molecule Neurotransmitter Profiles From the Crown-of-Thorns Seastar Radial Nerve Revealed Between Sexes and Following Food-Deprivation
TLDR
The metabolomic profiles of small molecule neurotransmitters in the COTS radial nerve cord are investigated to advance knowledge of echinoderm neural signaling processes but also identify potential targets for developing novel approaches for COTS biocontrol.
Melatonin as a Hormone: New Physiological and Clinical Insights.
TLDR
Maternal melatonin programs the fetuses' behavior and physiology to cope with the environmental light/dark cycle and season after birth, and unique ways of action turn melatonin into a biological time-domain-acting molecule.

Emerging roles of melatonin in mitigating abiotic and biotic stresses of horticultural crops
Circadian rhythm in melatonin release as a mechanism to reinforce the temporal organization of the circadian system in crayfish
TLDR
Results suggest that the circadian increase in MEL content directly affects the CG, reducing its spontaneous electrical activity, and that MEL might act as a periodical signal to reinforce the organization of the circadian system in crayfish.
New Insights Into the Evolutionary History of Melatonin Receptors in Vertebrates, With Particular Focus on Teleosts
TLDR
New insights are provided into the repertoire diversification and functional evolution of the mtnr gene family in vertebrates and the tissue distribution of mtnR expression in a large range of tissues in medaka.
Seasonal expression patterns of clock-associated genes in the blue mussel Mytilus edulis
TLDR

Photoperiodism and effects of indoleamines in a unicellular alga, Gonyaulax polyedra.
TLDR
Melatonin and an analog of 5-methoxytryptamine, substances that had previously been shown to occur in Gonyaulax, provoked cyst formation, suggesting a common biochemical basis of photoperiodism.
Non‐vertebrate melatonin
TLDR
Melatonin has been detected in bacteria, eukaryotic unicells, macroalgae, plants, fungi and various taxa of invertebrates, findings with possible implications in ecophysiology as well as for human nutrition and, with regard to high levels in medicinal plants, also in pharmacology.

TLDR
In dinoflagellates, the most spectacular actions concerning the stimulation of bioluminescence, changes in cytoplasmic pH and induction of resting stages, can be related to a metabolite of melatonin, the 5-methoxytryptamine; therefore, melatonin should also be considered as a source of other agonists.
Melatonin in higher plants: occurrence and possible functions
TLDR
Melatonin was shown to delay flower induction in some photoperiodic plants and in the dinoflagellate Lingulodinium it replaces, in part, the requirement of darkness for cyst formation.

TLDR
Melatonin is not only a hormone but is also synthesized in numerous extrapineal sites, in which it sometimes attains much higher quantities than in the pineal and the circulation, and is a source of bioactive metabolites, such as 5-methoxytryptamine, N1-acetyl-N2-formyl-5- methoxykynuramine and N1.methoxyKynuramines.

Melatonin Biosynthesis in Drosophila: Its Nature and Its Effects
TLDR
Drosophila melanogaster homogenates incubated with tritiated 5‐hydroxytryptophan, 5‐ hydroxytryptamine, or N‐acetylserotonin have the ability of converting them into labelled indolamines, including melatonin, and the injection of pharmacological doses of melatonin into 2‐day‐old female flies diminishes the mating speed and the oviposition rate.
Melatonin activity rhythms in eyes and cerebral ganglia of Aplysia californica.
TLDR
The results suggest that melatonin is produced in A. californica in a rhythmic pattern different from that associated with pineal melatonin production in vertebrates.
