The present review summarizes the current understanding of Nitric oxide-melatonin crosstalk in plants manifested by redox homoeostasis, regulation of gene expression and developmental changes. It further addresses the question of the possible role of NO-melatonin crosstalk to be operative through N-nitrosomelatonin formation (NOmela) in plants. Although NOmela appears to be a nascent molecule in plant systems, investigations on nitric oxide-melatonin cross talk in relation to abiotic stress tolerance, fruit ripening and morphogenesis in plants have emerged as new avenues of research in the recent past. Similar to animal systems, plants have also been suggested to possess both positive and antagonistic interactions between nitric oxide and melatonin. In this context, N-nitrosomelatonin is likely to function as another unique biomolecule associated with redox signaling and long-distance communication in plants. Localization and quantification of N-nitrosomelatonin are expected to provide new insights to the current understanding of NO-melatonin cross talk in plants. Methodological advances in imaging, isolation, and quantification of such transient molecule requires further attention. The present review provides an update on the prospects of NO-melatonin cross talk and N-nitrosomelatonin biology in plants. The quest for the biological role of NOmela in plants must lure physiologists to pursue the investigation with solid experimental evidences.

Nitric oxide (NO) is a free radical synthesized mainly by nitric oxide synthases (NOSs). NO regulates many aspects in sperm physiology in different species. However, in vitro studies investigating NOS...
This study aims to investigate the pharmacologic consequence of genetic deletion of nitric oxide synthase 3 (NOS3) in caveolin 1 (Cav1)-/- mice (double knockout [DKO]) in response to a nitric oxide (N...
Fine particulate matter (PM) has been widely associated with airway inflammation represented by increased fractional concentration of exhaled nitric oxide (FeNO). However, it remains unclear whether v...
Gases such as ethylene, hydrogen peroxide (H O ), nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H S) have been recognized as vital signaling molecules in plants and animals. Of these ...
Several signaling pathways have been shown to be involved in the regulation of pollen germination and pollen tube elongation. Among others, exogenously applied polyamines were found to strongly affect...
This blinded, placebo-controlled study will administer inhaled nitric oxide to patients undergoing liver transplantation. The purpose of the study is to test if inhaled nitric oxide preven...
A minimum of 100 patients will be enrolled in the study to demonstrate which diagnostic treatment (oxygen or nitric oxide) is most capable of identifying patients with a reactive pulmonary...
The purpose of this study is to determine whether inhaled nitric oxide is an effective treatment for microcirculatory dysfunction and acute organ system failure in the early stage of sepsi...

The purpose of this study is to assess the safety and efficacy of inhaled nitric oxide in prevention of lung graft dysfunction due to ischemia-reperfusion
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
An NADPH-dependent enzyme that catalyzes the conversion of L-ARGININE and OXYGEN to produce CITRULLINE and NITRIC OXIDE.
A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in ENDOTHELIAL CELLS.
A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in NERVE TISSUE.
The process of gene expression is used by eukaryotes, prokaryotes, and viruses to generate the macromolecular machinery for life. Steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-tran...
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
