ABSTRACT Melatonin ( N ‐acetyl‐5‐methoxytryptamine), a well‐known mammalian hormone, has been having great relevance in the Plant World recent years. Many of its physiological actions plants are leading to possible features agronomic interest, especially those related improvements tolerance stressors and postharvest life fruits vegetables. Thus, through exogenous application melatonin or by modifying endogenous biosynthesis phytomelatonin, some change can be made functional levels tissues their responses. Also, acting respective phytomelatonin enzymes, regulating expression tryptophan decarboxylase TDC ), tryptamine 5‐hydroxylase T5H serotonin ‐acetyltransferase SNAT ‐acetylserotonin O ‐methyltransferase ASMT caffeic acid COMT recently action deacetylases on intermediates offers promising opportunities for improving vegetables marketability. Other regulators/effectors such as different transcription factors, protein kinases, phosphatases, miRNAs, protein–protein interactions, gasotransmitters nitric oxide hydrogen sulfide were also considered an exhaustive vision. interesting aspects role autophagic responses, posttranslational reprogramming protein‐phosphorylation, ubiquitylation, SUMOylation, PARylation, persulfidation, nitrosylation described phytomelatonin‐mediated responses discussed, including relationship several plant hormones, chilling injury fungal decay alleviating. The current data about receptor (CAND2/PMTR1), effect UV‐B light cold storage damage presented discussed. All this focus new preservation quality

Abstract The postharvest lifespan of horticultural products is closely related to loss nutritional quality, accompanied by a rapid decline in shelf life, commercial value, and marketability. Melatonin (MT) application not only maintains quality but also delays senescence products. This paper reviews biosynthesis metabolism endogenous MT, summarizes significant effects exogenous MT on products, examines regulatory mechanisms MT‐mediated effects, provides an integrated review for understanding the positive role delay maintenance. As multifunctional molecule, coordinates other signal molecules, such as ABA, ETH, JA, SA, NO, Ca 2+ , regulate ripening senescence. Several metabolic pathways are involved regulation during senescence, including synthesis transduction plant hormones, redox homeostasis, energy metabolism, carbohydrate degradation pigment cell wall components. Moreover, regulates expression genes antioxidant systems, generation, fruit firmness colour, membrane integrity, storage. Consequently, could become emerging eco‐friendly preservative extend life maintain

The untargeted metabolomics of Newhall navel oranges from three areas in China—Ganzhou, Fengjie, and Zigui—with geographical indication (GI) was measured using LC-MS/MS. Orthogonal partial least squares discriminant analysis performed for sample classification important metabolite identification. This approach identified the best markers origin able to discriminate Ganzhou, Zigui orange samples. For peeled samples, 2-isopropylmalic acid, succinic citric L-aspartic L-glutamic γ-semialdehyde, D-β-phenylalanine, hesperetin, hydrocinnamic 4-hydroxycinnamic dehydroascorbate were used origin. All these overexpressed samples area, followed by Ganzhou area. As unpeeled isovitexin 2′-O-β-D-glucoside, isovitexin, diosmetin, trans-2-hydroxycinnamate trans-cinnamate, β-carotene their first seven Zigui-planted whole showed highest levels, last richest Ganzhou-planted According variation discriminating origins or with GI value titratable acidity those Zigui, planted have balance between taste nutrition. work confirms that combined OPLS-DA is an effective way tracing overall quality evaluation.

Melatonin (MT) is an elicitor that stimulates phenolic compounds biosynthesis and accumulation in fruits vegetables. However, its role regulating the phenylpropane metabolism during pepper ripening unclear. To investigate how exogenous MT regulates ripening, plant surfaces were sprayed with different concentrations (0 100 µmol·L-1) 10 days after anthesis. treatment improved quality. In particular, total phenolics flavonoids levels elevated, indicating affected metabolism. Furthermore, metabolomics identified 15 substances exhibiting high fold-change values treatment, including chlorogenic acid, gallic ferulic caffeic cynarin, p-coumaric cinnamic gentianic benzoic sinapic p-hydroxybenzoic protocatechuic rutin, quercetin, kaempferol. Shikimate dehydrogenase, phenylalanine ammonia-lyase, cinnamate-4-hydroxylase, 4-coumarate-Coa ligase, chalcone synthase, isomerase activities also evaluated. upregulated expression of genes involved synthesis corresponding endogenous anabolic pathway, promoting endogenous. The polyphenolics carbohydrates are indicators botanical geographical origin Serbian autochthonous clones red spice throughout ripening. summary, accelerates by activating modulating hormone signaling networks. This expected to offer a revolutionary strategy reinforce plants resistance

The impact of emerging stressors, such as pesticides and heavy metals, on the nutritional quality, resistance, antioxidant systems crops is subject intense monitoring. Due to its low toxicity biocompatibility, nano-selenium (nano-Se) increases capacity more effectively than selenium (Se). However, protective mechanism nano-Se in plum trees still unknown when subjected long-term abiotic stress. In this study, foliar application enhanced fruit's fresh weight diameter plant growth development by increasing content trace elements (Zn Se) amino acids (Try, Phe, Pro, Arg) leaves fruits. Compared control, treatment dramatically improved plant's system, resulting a substantial increase SOD (44.3 %), POD (24.3 CAT (95.6 %) levels. It also increased IAA (118.8 total flavonoids (23.0 phenols (15.8 rutin (37.7 quercetin (146.8 caffeic acid (19.8 contents regulating phenylpropane metabolic pathways. Targeted analysis indicated that biofortification greatly levels His (60.7 Ser (123.5 Thr (105.7 Val (202.1 Ile (236.2 Leu (84.0 Tyr (235.0 Phe (164.7 %). non-target metabolomics results showed stimulated nutrition boosting metabolism production. Therefore, can improve quality resistance plums both primary secondary pathways plants enhancing capacity. This investigation provides reference for extrapolating positive effects crop other species.

Abstract BACKGROUND In order to comprehend the regulatory mechanisms that result in alleviation of sweet cherry pitting disorder through cold shock (0 °C ice–water mixture for 10 min), an investigation was conducted into impacts treatment (CST) on membrane lipid metabolism, antioxidant enzyme activity, as well cold‐stored fruit. RESULTS CST significantly inhibited increase incidence, index, and decay incidence. The provided greater titratable acidity, firmness total content soluble solids. use prevented build‐up superoxide anions, hydrogen peroxide, malondialdehyde, reduced permeability cell membranes. When contrast control group, also raised expression levels along with activity enzymes ascorbate peroxidase (APX), glutathione reductase (GR), dismutase (SOD), catalase (CAT). Furthermore, amount fruit peroxidation, suppressed phospholipase lipoxygenase, postponed rise saturated fatty acids (SFAs) decrease unsaturated (USFAs), ultimately keeping a high ratio USFAs SFAs. CONCLUSION can alleviating via preventing peroxidation elevating activity. © 2024 Society Chemical Industry.
