Published: July 30, 2022

Abstract Background Melatonin is a multi-functional molecule widely employed in order to mitigate abiotic stress factors, general and salt particular. Even though previous reports revealed that melatonin could exhibit roles promoting seed germination protecting plants during various developmental stages of several plant species under stress, no are available with respect the regulatory acts on physiological biochemical status as well expression levels defense- secondary metabolism-related related transcripts bitter melon subjected stress. Results Herewith present study, we performed comprehensive analysis ion balance, antioxidant system, transcript defense-related genes ( WRKY1 , SOS1, PM H + -ATPase, SKOR, Mc5PTase7 SOAR1 ) gene MAP30, α-MMC polypeptide-P PAL salt-stressed Momordica charantia L.) response treatment. In this regard, different (0, 75 150 µM) were applied salinity 50 100 mM NaCl) melon.

Function, Mechanism, and Application of Plant Melatonin: An Update with a Focus on the Cereal Crop, Barley (Hordeum vulgare L.)

Antioxidants, Journal Year: 2022, Volume and Issue: 11(4), P. 634 - 634

Published: March 25, 2022

Melatonin is a multiple-function molecule that was first identified in animals and later plants. Plant melatonin regulates versatile processes involved plant growth development, including seed germination, root architecture, flowering time, leaf senescence, fruit ripening, biomass production. Published reviews on have been focused two model plants: (1) Arabidopsis (2) rice, which the natural contents are quite low. Efforts to integrate function mechanism of determine how benefits human health also lacking. Barley unique cereal crop used for food, feed, malt. In this study, bioinformatics analysis identify genes required barley biosynthesis performed, after effects exogenous development were reviewed. Three integrated mechanisms cells found: serving as an antioxidant, modulating hormone crosstalk, (3) signaling through putative receptor. Reliable approaches characterizing biosynthetic modulate grains discussed. The present paper should be helpful improvement production under hostile environments reduction pesticide fungicide usage cultivation. This study beneficial enhancement nutritional values healthcare functions food industry.

Melatonin is a multifunctional molecule that has been widely discovered in most plants. An increasing number of studies have shown melatonin plays essential roles plant growth and stress tolerance. It extensively applied to alleviate the harmful effects abiotic stresses. In view its role regulating aspects development, we ponder summarize scientific discoveries about seed germination, root flowering, fruit maturation, senescence. Under biotic stresses, brings together many pathways increase access treatments for symptoms plants counteract negative effects. capacity tackle regulation redox, hormone networks, endogenous melatonin. Furthermore, expression levels several genes contents diverse secondary metabolites, such as polyphenols, terpenoids, alkaloids, were significantly altered. this review, intend examine actions from broader perspective, explore range physiological functions, analyze relationship between other metabolites metabolic pathways.

Biosynthetic Pathways of Hormones in Plants

Metabolites, Journal Year: 2023, Volume and Issue: 13(8), P. 884 - 884

Published: July 25, 2023

Phytohormones exhibit a wide range of chemical structures, though they primarily originate from three key metabolic precursors: amino acids, isoprenoids, and lipids. Specific such as tryptophan, methionine, phenylalanine, arginine, contribute to the production various phytohormones, including auxins, melatonin, ethylene, salicylic acid, polyamines. Isoprenoids are foundation five phytohormone categories: cytokinins, brassinosteroids, gibberellins, abscisic strigolactones. Furthermore, lipids, i.e., α-linolenic function precursor for jasmonic acid. The biosynthesis routes these different plant hormones intricately complex. Understanding processes can greatly enhance our knowledge how regulate growth, development, physiology. This review focuses on detailing biosynthetic pathways phytohormones.

Reactive Oxygen Species: A Crosslink between Plant and Human Eukaryotic Cell Systems

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(17), P. 13052 - 13052

Published: Aug. 22, 2023

Reactive oxygen species (ROS) are important regulating factors that play a dual role in plant and human cells. As the first messenger response organisms, ROS coordinate signals growth, development, metabolic activity pathways. They also can act as an alarm mechanism, triggering cellular responses to harmful stimuli. However, excess cause oxidative stress-related damage oxidize organic substances, leading malfunctions. This review summarizes current research status mechanisms of eukaryotic cells, highlighting differences similarities between two elucidating their interactions with other reactive substances ROS. Based on similar regulatory pathways kingdoms, this proposes future developments provide opportunities develop novel strategies for treating diseases or creating greater agricultural value.
