Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Inhospitable conditions that hinder plant growth and development encompass a range of abiotic stresses, such as drought, extreme temperatures (both low high), salinity, exposure to heavy metals, irradiation. The cumulative impact these stresses leads considerable reduction in agricultural productivity worldwide. generation reactive oxygen species (ROS) is shared mechanism toxicity induced by all stimuli plants, resulting oxidative damage membrane instability. Extensive research has shed light on the dual role melatonin where it serves both regulator, fostering development, potent protector against stresses. inherent potential function natural antioxidant positions promising biostimulant for use, bolstering plants' abilities withstand wide array environmental challenges. Beyond its properties, demonstrated capacity regulate expression genes associated with photosynthetic process. This additional characteristic enhances appeal versatile chemical agent can be exogenously applied particularly adverse conditions, improve their resilience optimize efficiency every phase life cycle. An examination molecular mechanisms underlying stress-protective effects exogenous machinery plants under various presented this paper. In addition, future prospects are discussed developing stress-tolerant crops sustainable agriculture challenging environments.

Cereal crops are crucial for global food security; however, they susceptible to various environmental stresses that significantly hamper their productivity. In response, melatonin has emerged as a promising regulator, offering potential benefits stress tolerance and crop growth. This review explores the effects of on maize, sorghum, millet, rice, barley, wheat, aiming enhance resilience stress. The application shown outcomes, improving water use efficiency reducing transpiration rates in millet under drought conditions. Furthermore, it enhances salinity heavy metal by regulating activity stress-responsive genes. Similarly, sorghum its resistance high temperatures, low humidity, nutrient deficiency, potentially involving modulation antioxidant defense aspects related photosynthetic Melatonin also exerts protective against drought, salinity, metal, extreme waterlogging barley decreasing reactive oxygen species (ROS) production through system. molecular reactions upregulated photosynthesis, mechanisms, metabolic pathway, genes downregulated susceptibility conclusion, serves versatile tool cereal crops, bolstering promoting sustainable development. Further investigations warranted elucidate underlying mechanisms refine techniques fully harness role systems.

Melatonin is a hormone-like substance that serves as secondary metabolite associated with variety of physiological, hormonal, and natural processes at the cell, tissue, organ levels. It acts plant biostimulant increase tolerance against abiotic stresses like ssalinity, drought, heat, cold heavy metals. in plants, also called phytomelatonin, participating cellular mechanisms ameliorates oxidative toxicity, hence helps to stand stress conditions. These exclusive properties strengthen defense capacity by stimulating detoxification reactive oxygen species (ROS), promoting physiological attributes, activation stress-responsive genes ameliorate toxicity caused stress. As key molecule, it exhibits several important molecular interactions nitric oxide (NO), calcium (Ca2+), hydrogen peroxide (H2O2) sulfide (H2S). In this review article, we discuss salient role melatonin morphological adaptation well its involvement mitigation. Besides, under stress, interaction NO, Ca2+, H2O2, H2S has been demonstrated. This study will provide reference for elucidating regulatory mechanism influencing resistance plants.

Leaf senescence reduces the photosynthetic capacity of leaves, thus significantly affecting growth, development, and yield formation cotton. Melatonin (MT) is a multipotent substance proven to delay leaf senescence. However, its potential mechanism in delaying induced by abiotic stress remains unclear. This study aimed explore effect MT on drought-induced cotton seedlings clarify morphological physiological mechanisms. Drought upregulated marker genes, destroyed photosystem, led excessive accumulation reactive oxygen species (ROS, e.g., H2O2 O2-), accelerating was delayed when 100 μM sprayed leaves seedlings.

Melatonin is a ubiquitous regulator in plants and performs variety of physiological roles, including resistance to abiotic stress, regulation growth development, enhancement plant immunity. exhibits the characteristics phytohormone with its pleiotropic effects, biosynthesis, conjugation, catabolism, effective concentration, shape location dose-response curves. In addition, CAND2/PMTR1, phytomelatonin receptor candidate belonging G protein-coupled receptors (GPCRs), supports concept melatonin as phytohormone. However, biochemistry needs be further characterized. particular, some experimental findings date cannot explained by known GPCR signaling mechanisms, so studies are needed explore possibility novel mechanisms.
