The involvement of melatonin in the regulation salt stress acclimation has been shown plants this present work. We found that GOAL cultivar wheat (Triticum aestivum L.) was most salt-tolerant among investigated cultivars, GOAL, HD-2967, PBW-17, PBW-343, PBW-550, and WH-1105 when screened for tolerance to 100 mM NaCl. application μM maximally reduced oxidative improved photosynthesis cv.

Melatonin supplementation stress-induced by upregulating activity antioxidant enzymes, such as superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR), (GSH) production. This resulted increased membrane stability, photosynthetic-N use efficiency plants. 50 ethylene biosynthesis inhibitor aminoethoxyvinylglycine (AVG) presence H2 O2 content but GR GSH, photosynthesis, plant dry mass. signifies melatonin-mediated related synthesis it under stress. Thus, interaction bears a prominent role can be used develop other crops.

Tomato is an important vegetable that highly sensitive to drought (DR) stress which impairs the development of tomato seedlings. Recently, melatonin (ME) has emerged as a nontoxic, regulatory biomolecule regulates plant growth and enhances DR tolerance mechanism in plants. The present study was conducted examine defensive role ME photosynthesis, root architecture, antioxidant enzymes' activities seedlings subjected stress. Our results indicated strongly suppressed biomass production, inhibited negatively affected morphology, reduced photosynthetic pigments Per contra, soluble sugars, proline, ROS (reactive oxygen species) were suggested be improved under Conversely, (100 µM) pretreatment detrimental-effect by restoring chlorophyll content, gas exchange parameters attributes compared with DR-group only. Moreover, supplementation also mitigated enzymes [APX (ascorbate peroxidase), CAT (catalase), DHAR (dehydroascorbate reductase), GST (glutathione S-transferase), GR MDHAR (monodehydroascorbate POD (peroxidase), SOD (superoxide dismutase)], non-enzymatic [AsA (ascorbate), DHA (dehydroascorbic acid), GSH (glutathione), GSSG, (oxidized glutathione)] activities, oxidative damage [EL (electrolyte leakage), H2O2 (hydrogen peroxide), MDA (malondialdehyde), O2•- ion)] osmoregulation (soluble sugars proline) seedlings, regulating gene expression for SOD, CAT, APX, GR, POD, GST, DHAR, MDHAR. These findings determine could efficiently improve growth, characteristics, leaf photosynthesis machinery thereby increasing seedlings' adaptability

Phytomelatonin, a multifunctional molecule that has been found to be present in all plants examined date, an important role as modulatory agent (a biostimulator) improves plant tolerance both biotic and abiotic stress. We review of phytomelatonin considers its roles metabolism particular interactions with hormone network. In the primary plants, melatonin rate efficiency photosynthesis, well related factors such stomatal conductance, intercellular CO2, Rubisco activity. It also shown down-regulate some senescence transcription factors. Melatonin up-regulates many enzyme transcripts carbohydrates (including sucrose starch), amino acids, lipid metabolism, optimizing N, P, S uptake. With respect secondary clear increases polyphenol, glucosinolate, terpenoid, alkaloid contents have described numerous melatonin-treated plants. Generally, most genes these biosynthesis pathways up-regulated by melatonin. The great regulatory capacity is result control redox networks. acts master regulator, up-/down-regulating different levels signalling, key player homeostasis. counteract diverse critical situations pathogen infections stresses, provide varying degrees tolerance. propose possible future applications for crop improvement post-harvest product preservation.

Tomato is an essential annual crop providing human food worldwide. It estimated that by the year 2050 more than 50% of arable land will become saline and, in this respect, recent years, researchers have focused their attention on studying how tomato plants behave under various conditions. Plenty research papers are available regarding effects salinity plant growth and development, provide information behavior different cultivars salt concentrations, or experimental protocols analyzing parameters. This review gives a synthetic insight scientific advances relevant into morphological, physiological, biochemical, yield, fruit quality parameters, gene expression plants. Notably, works assessed tomatoes were firstly identified Scopus, PubMed, Web Science databases, followed sifter according to Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) guideline with emphasis results. The assessment selected studies pointed out one factors significantly affecting all stages development. Therefore, find solutions increase tolerance stress needed. Furthermore, findings reported helpful select, apply appropriate cropping practices sustain market demand scenario increasing lands due soil water deficit, use low-quality farming intensive agronomic practices.
