The pathogenesis‐related (PR) proteins of plants have originally been identified as proteins
that are strongly induced upon biotic and abiotic stress. These proteins fall into 17 distinct …

Abiotic stresses, such as drought, salinity, heat, cold, and heavy metals, are associated with
global climate change and hamper plant growth and development, affecting crop yields and …

Phytomelatonin, a multifunctional molecule that has been found to be present in all plants
examined to date, has an important role in plants as a modulatory agent (a biostimulator) …

Melatonin, a product of tryptophan metabolism via serotonin, is a molecule with an indole
backbone that is widely produced by bacteria, unicellular eukaryotic organisms, plants, fungi …

Plants being sessile in nature, are exposed to unwarranted threats as a result of constantly
changing environmental conditions. These adverse factors can have negative impacts on …

Melatonin acts as a multifunctional molecule that takes part in various physiological
processes, especially in the protection against abiotic stresses, such as salinity, drought …

The expansion of gene families during evolution could generate functional diversity among
their members to regulate plant growth and development. Melatonin, a phylogenetically …

Phytomelatonin is a universal signal molecule that regulates plant growth and stress
responses; however, only one receptor that can directly bind with and perceive melatonin …

Melatonin is a highly conserved and ubiquitous molecule that operates upstream of a broad
array of receptors in animal systems. Since melatonin was discovered in plants in 1995 …

Melatonin is an essential phytohormone in the regulation of many plant processes, including
during plant development and in response to stress. Pathogen infections cause serious …
