Melatonin regulates the growth of roots, shoots, and explants, to activate seed germination and rhizogenesis and to delay induced leaf senescence. The antioxidant properties of melatonin would seem to explain, at least partially, its ability to fortify plants subjected to abiotic stress. In this Review we examine recent data on the gene-regulation capacity of melatonin that point to many interesting features, such as the upregulation of anti-stress genes and recent aspects of the auxin… Expand
Growth activity, rooting capacity, and tropism: three auxinic precepts fulfilled by melatonin
TLDR
This review presents data that relate the physiological responses produced by melatonin with the action of auxin, such as promoting/inhibiting growth activity and rooting capacity, and demonstrates the possible involvement of melatonin in the tropic response of roots. Expand
Melatonin as Master Regulator in Plant Growth, Development and Stress Alleviator for Sustainable Agricultural Production: Current Status and Future Perspectives
TLDR
The main functions of melatonin in the physiology, growth, development and regulation of higher plants are outlined and its role as anti-stressor agent against various abiotic stressors, such as drought, salinity, temperatures, UV radiation and toxic chemicals is analyzed critically. Expand
Melatonin: a master regulator of plant development and stress responses.
TLDR
The biosynthesis of melatonin from tryptophan is described, as well as its various degradation pathways in plants, and it is proposed that melatonin is a master regulator in plants. Expand
Phytomelatonin: a universal abiotic stress regulator
TLDR
The interactions ofmelatonin with phytohormones to regulate downstream gene expression, protein stabilization, and epigenetic modification in plants are summarized and the need for, and approaches to, the identification of melatonin receptors and components during signaling transduction pathways are considered. Expand
Melatonin in business with abiotic stresses in plants.
TLDR
Different aspects ofmelatonin in plants such as melatonin biosynthesis and detection in plants, signaling pathway, modulation of stress related genes and physiological role of melatonin under different environmental stresses have been dissected in detail. Expand
Effect of melatonin priming on photosynthetic capacity of tomato leaves under low-temperature stress
TLDR
Melatonin priming both in the form of leaf spray and direct root application was found to reduce the damage to photosynthetic apparatus, and increase the electron transfer rate and quantum yield of PSI and PSII photochemistry, to protect the thylakoid membrane from damage caused by low-temperature stress. Expand
Exogenous melatonin enhances salt stress tolerance in tomato seedlings
Melatonin (N-acetyl-5-methoxytryptamine) is an essential molecule which regulates plant growth and development and alleviates the damaging effects of abiotic stresses. To evaluate the importantExpand
Melatonin: A New Plant Hormone and/or a Plant Master Regulator?
TLDR
The recent identification of the first plant melatonin receptor opened the door to this regulatory molecule being considered a new plant hormone, and the most recent data are discussed. Expand
Melatonin Mediates Enhancement of Stress Tolerance in Plants
TLDR
Melatonin acted as a powerful growth regulator, bio-stimulator, and antioxidant, which delayed leaf senescence, lessened photosynthesis inhibition, and improved redox homeostasis and the antioxidant system under abiotic and biotic stress conditions. Expand

Growth conditions influence the melatonin content of tomato plants.
TLDR
How cultivation conditions decisively influence melatonin levels in roots, stems and leaves of tomato plants is described, and some guidelines for interpreting data are established with the intention of opening up new discussion options, given the lack of data on the place/s of melatonin biosynthesis and its mode of action in plant cells as an antioxidant. Expand
Growth conditions determine different melatonin levels in Lupinus albus L
TLDR
Melatonin biosynthesis is upregulated in common stress situations, in which it may serve as a signal molecule and/or as a direct antistress agent due to its well‐known antioxidative properties. Expand
Profiling of melatonin in the model tomato (Solanum lycopersicum L.) cultivar Micro‐Tom
TLDR
In fruits and leaves, melatonin concentrations varied depending on the developmental stage, suggesting that melatonin controls some of the processes involved in plant maturation. Expand
Melatonin regulates Arabidopsis root system architecture likely acting independently of auxin signaling
TLDR
The results suggest that melatonin is beneficial to plants by increasing root branching and that root development processes elicited by this novel plant signal are likely independent of auxin responses. Expand
Role of melatonin in alleviating cold stress in Arabidopsis thaliana
TLDR
The up‐regulation of cold signaling genes by melatonin may stimulate the biosynthesis of cold‐protecting compounds and contribute to the increased growth of plants treated with exogenous melatonin under cold stress. Expand
Exogenously applied melatonin stimulates root growth and raises endogenous indoleacetic acid in roots of etiolated seedlings of Brassica juncea.
TLDR
The results show that 0.1microM melatonin has a stimulatory effect on root growth, while 100microM is inhibitory, and older seedlings appear to be less susceptible to both the stimulatory and the inhibitory effect of melatonin. Expand
Transient induction of melatonin biosynthesis in rice (Oryza sativa L.) during the reproductive stage
TLDR
The results suggest that the induction of melatonin during flower development is regulated by the transcriptional control of its biosynthesis genes and that melatonin may participate in flower development. Expand
Delay in leaf senescence of Malus hupehensis by long‐term melatonin application is associated with its regulation of metabolic status and protein degradation
TLDR
Evidence is provided for this delay in senescence based on the metabolic alteration and protein degradation in trees of Malus hupehensis Rehd. Expand
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. Expand
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. Expand
