Growth activity, rooting capacity, and tropism: three auxinic precepts fulfilled by melatonin

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.

Melatonin as Master Regulator in Plant Growth, Development and Stress Alleviator for Sustainable Agricultural Production: Current Status and Future Perspectives

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.

Phytomelatonin: a universal abiotic stress regulator

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.

Melatonin and Indole-3-Acetic Acid Synergistically Regulate Plant Growth and Stress Resistance

This article reviews studies on the signaling pathways of melatonin and IAA, focusing on specific regulatory mechanisms, and suggests that, at low concentrations, melatonin promotes IAA synthesis, whereas at high levels it reduces IAA levels.

Melatonin in business with abiotic stresses in plants

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.

Effect of melatonin priming on photosynthetic capacity of tomato leaves under low-temperature stress

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.

Melatonin Mediates Enhancement of Stress Tolerance in Plants

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.

Melatonin in Plant Defense against Abiotic Stress

The current study was undertaken to elaborate the synthesis and regulation of melatonin in plants, besides emphasizing its function under various abiotic stress namely, salt, temperature, herbicides, heavy metals, and drought.

Growth conditions determine different melatonin levels in Lupinus albus L

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.

Profiling of melatonin in the model tomato (Solanum lycopersicum L.) cultivar Micro‐Tom

In fruits and leaves, melatonin concentrations varied depending on the developmental stage, suggesting that melatonin controls some of the processes involved in plant maturation.

Melatonin regulates Arabidopsis root system architecture likely acting independently of auxin signaling

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.

Role of melatonin in alleviating cold stress in Arabidopsis thaliana

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.

Transient induction of melatonin biosynthesis in rice (Oryza sativa L.) during the reproductive stage

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.

Delay in leaf senescence of Malus hupehensis by long‐term melatonin application is associated with its regulation of metabolic status and protein degradation

Evidence is provided for this delay in senescence based on the metabolic alteration and protein degradation in trees of Malus hupehensis Rehd.

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 stimulates the expansion of etiolated lupin cotyledons

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

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.
