Low-temperature storage is an effective method to extend the shelf life of harvested winter jujube fruit; however, quality fruit decreases after refrigeration. To enhance with minimum qualitative deterioration during cold storage, this study investigated effects different melatonin concentration (100, 150, and 200 µmol/L) treatments on (during white ripening stage) at 0 ± 1 °C (RH, 90 5%) for days. The relative indexes antioxidant system were measured every 15 results showed that concentrations could maintain fruit's firmness, retard redness, inhibit decrease in weight, total soluble solid (TSS), titratable acidity (TA), contents phenols, flavonoids, glutathione, ascorbic acid; they also inhibited increase conductivity, malondialdehyde (MDA), hydrogen peroxide (H2O2) content fruits enhanced enzyme activities (superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), (POD)).

Experimental approaches in studying active biomolecules modulating fruit ripening: Melatonin as a case study

PLANT PHYSIOLOGY, Journal Year: 2023, Volume and Issue: 192(3), P. 1747 - 1767

Published: Feb. 21, 2023

Abstract Phytohormones are naturally occurring small organic molecules found at low concentrations in plants. They perform essential functions growth and developmental processes, from organ initiation to senescence, including fruit ripening. These regulatory studied using different experimental approaches, such as performing exogenous applications, evaluating endogenous levels, and/or obtaining genetically modified lines. Here, we discuss the advantages limitations of current approaches used study active biomolecules modulating ripening, focusing on melatonin. Although melatonin has been implicated ripening several model crops, knowledge is affected by used, which have given sometimes even contradictory results. The methods application doses produced results studies based while measurement ways expressing explain most variability correlative analyses. Furthermore, crops focused tomato (Solanum lycopersicum L.) plants only. However, TILLING CRISPR methodologies becoming tools complement described above. This will not only help scientific community better understand role but it also develop technological advances improve yield quality major crops. combination various undoubtedly lead a complete understanding function near future, so that this can be effectively transferred field.

Crosstalk between melatonin and reactive oxygen species in fruits and vegetables post-harvest preservation: An update

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: March 3, 2023

Fruits and vegetables contain numerous nutrients, such as vitamins, minerals, phenolic compounds, dietary fibers. They reduce the incidence of cardiovascular diseases risk certain chronic diseases, improve antioxidant anti-inflammatory capacity. Moreover, melatonin was found in various fruits species. Melatonin acts a multifunctional compound to participate physiological processes. In recent years, many advances have been that is also appraised key modulator on post-harvest preservation. usually elicit reactive oxygen species (ROS) generation accumulation. Excess ROS stimulate cell damage, protein structure destruction, tissue aging, thereby reducing their quality. Numerous studies find exogenous application modulates homeostasis by regulating enzymes non-enzymatic antioxidants systems. Further evidences reveal often interacts with hormones other signaling molecules, ROS, nitric oxide (NO), hydrogen sulfide (H 2 S), etc. Among these ‘new’ crosstalks especially H O produced RBOHs, are provided preservation this review. It will provide reference for complicated integration both signal molecules future study.

Sweet Cherry (Prunus avium L.) Cracking during Development on the Tree and at Harvest: The Impact of Methyl Jasmonate on Four Different Growing Seasons

Agriculture, Journal Year: 2023, Volume and Issue: 13(6), P. 1244 - 1244

Published: June 14, 2023

Rainfall occurring during the developmental stages of sweet cherries on tree can lead to significant preharvest losses, primarily due fruit cracking. Certain cultivars exhibit a higher susceptibility such particularly when persistent rains coincide with advanced phenological stages. The current study aims investigate efficacy methyl jasmonate (MeJA) applications at harvest and distinct ripening in mitigating cherry cracking on-tree ripening. Preharvest foliar 0.5 mM MeJA were applied across various cultivars, including ‘Prime Giant’, ‘Early Lory’, ‘Sweetheart’, ‘Staccato’. By conducting this experiment over four growing seasons, we evaluated impact natural elicitor tolerance these cultivars. results our analysis indicate that treatments effectively reduce cracking, enhancing abiotic stress tolerance. Additionally, induce general delay examined This delayed effect is reflected several quality parameters harvest, as firmness, external colour, total soluble solids, acidity. These MeJA-treated compared control or remained unaffected for Conversely, accumulation polyphenols, exhibiting minimal reducing pedicel browning. enhanced attributed could be helpful plot management. Consequently, MeJA-based hold potential valuable tools adapting climate change cherry.

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.
