Melatonin Mediated Regulation of Drought Stress: Physiological and Molecular Aspects

Plants, Journal Year: 2019, Volume and Issue: 8(7), P. 190 - 190

Published: June 26, 2019

Drought stress adversely effects physiological and biochemical processes of plants, leading to a reduction in plant productivity. Plants try protect themselves via activation their internal defense system, but severe drought causes dysfunction this system. The imbalance between generation scavenging reactive oxygen species (ROS) leads oxidative stress. Melatonin, multifunctional molecule, has the potential plants from adverse by enhancing ROS efficiency. It helps protection photosynthetic apparatus induced Melatonin regulates at molecular level, which results providing better resistance against In review, authors have discussed various aspects regulated melatonin under conditions, along with underlying mechanisms.

Published: Sept. 14, 2018

Melatonin (N-acetyl-5-methoxytryptamine) is a nontoxic biological molecule produced in pineal gland of animals and different tissues plants. It an important secondary messenger molecule, playing vital role coping with various abiotic biotic stresses. serves as antioxidant postharvest technology enhances the life fruits vegetables. The application exogenous melatonin alleviated reactive oxygen species cell damage induced by stresses means repairing mitochondria. Additionally, regulation stress-specific genes activation pathogenesis-related protein enzymes under stress makes it more versatile molecule. Besides that, crosstalk other phytohormones inroads to utilize against non-testified conditions, such viruses nematodes. Furthermore, strategies have been discussed induce endogenous activity order sustain plant system. Our review highlighted diverse roles system, which could be useful enhancing environmental friendly crop production ensure food safety.

Arabidopsis serotonin N‐acetyltransferase knockout mutant plants exhibit decreased melatonin and salicylic acid levels resulting in susceptibility to an avirulent pathogen

Journal of Pineal Research, Journal Year: 2015, Volume and Issue: 58(3), P. 291 - 299

Published: Feb. 5, 2015

Abstract Serotonin N ‐acetyltransferase ( SNAT ) is the penultimate enzyme in melatonin biosynthesis pathway plants. We examined effects of gene inactivation two Arabidopsis T‐ DNA insertion mutant lines. After inoculation with avirulent pathogen Pseudomonas syringe pv. tomato DC 3000 harboring elicitor avrRpt2 Pst ‐avrRpt2), levels snat knockout lines were 50% less than wild‐type Col‐0 The exhibited susceptibility to infection that coincided decreased induction defense genes including PR 1 , ICS and PDF . 2 Because acts upstream salicylic acid SA synthesis, reduced led compared wild‐type, suggesting increased could be attributed subsequent attenuation induction.

Phytohormones as Growth Regulators During Abiotic Stress Tolerance in Plants

Frontiers in Agronomy, Journal Year: 2022, Volume and Issue: 4

Published: March 3, 2022

Phytohormones (PHs) play crucial role in regulation of various physiological and biochemical processes that govern plant growth yield under optimal stress conditions. The interaction these PHs is for survival stressful environments as they trigger signaling pathways. Hormonal cross initiate a cascade reactions which finely tune the architecture help to grow suboptimal Recently, studies have highlighted such abscisic acid, salicylic ethylene, jasmonates responses toward environmental stresses. involvement cytokinins, gibberellins, auxin, relatively novel strigolactones brassinosteroids development has been documented normal recent identification first melatonin receptor opened door this regulatory molecule being considered new hormone. However, polyamines, are not PHs, included chapter. Various microbes produce secrete hormones helped plants nutrient uptake N, P, Fe. Exogenous use correcting deficiency abiotic This chapter focused on developments knowledge related their stresses anticipation, signaling, cross-talk, activation response mechanisms. In view capability producing hormones, we propose potential strategy crop management.

Melatonin Improved Anthocyanin Accumulation by Regulating Gene Expressions and Resulted in High Reactive Oxygen Species Scavenging Capacity in Cabbage

Frontiers in Plant Science, Journal Year: 2016, Volume and Issue: 7

Published: March 23, 2016

In this work, we found, that exogenous melatonin pretreatment improved anthocyanin accumulation (1- to 2-fold) in cabbage. To verify the relationship with and anthocyanin, an Arabidopsis mutant, snat, which expresses a defective form of biosynthesis enzyme SNAT (Serotonin N-acetyl transferase), was employed. Under cold conditions, foliage wild-type exhibited deeper red color than snat mutant. This finding further proved, treatment able affect accumulation. gain better understanding how upregulates measured gene expression cabbage samples treated untreated controls. We found transcript levels biosynthetic genes were upregulated by treatment. Moreover, increased transcription factors MYB, bHLH, WD40, constitute transcriptional activation complex responsible for coordinative regulation genes. free radical generation downregulated, whereas osmotic adjustment antioxidant capacities melatonin-treated plants. concluded, increases production benefits growth.
