Melatonin is a ubiquitous indolamine, largely investigated for its key role in the regulation of
several physiological processes in both animals and plants. In the last century, it was …

Melatonin is a widespread molecule among living organisms involved in multiple biological,
hormonal, and physiological processes at cellular, tissue, and organic levels. It is well …

Plant melatonin research is a rapidly developing field. A variety of isoforms of melatonin's
biosynthetic enzymes are present in different plants. Due to the different origins, they exhibit …

Derived from tryptophan, melatonin is a nontoxic indolic molecule that is widely identified in
species ranging from bacteria to mammals. It plays vital roles in the circadian rhythm …

Melatonin (N-acetyl-5-methoxytryptamine) is a ubiquitous molecule with pleiotropic actions
in different organisms. It performs many important functions in human, animals, and plants; …

Phytomelatonin (plant melatonin) is chemically related to the amino acid tryptophan and has
many diverse properties. Phytomelatonin is an interesting compound due to its outstanding …

The discovery of melatonin (N-acetyl-5-methoxytryptamine) in plants occurred just over a
decade ago [1–3]. For roughly 35 years before that, melatonin was known to be the indole …

Melatonin is an ancient molecule that can be traced back to the origin of life. Melatonin's
initial function was likely that as a free radical scavenger. Melatonin presumably evolved in …

Melatonin (N-acetyl-5-methoxy-tryptamine) is a mammalian neurohormone, antioxidant and
signaling molecule that was first discovered in plants in 1995. The first studies investigated …

Melatonin has been detected in numerous plant species. A particularly surprising finding
concerns the highly divergent levels of melatonin that vary between species, organs and …
