“…These outcomes demonstrated that NPs enhanced fruit quality. Previously it has been reported that the weight loss of persimmons resulted in the fruit's withering, weakening, and declining quality (Bagheri et al, 2015). According to Menna et al (2020), Cu-chitosan nano substantially decreased weight loss in tomatoes, which is in line with the results of our investigation.…”

Postharvest fungal attacks on fruits such as apricots and loquats are common. Diseased fruit samples were collected from Murree's local fruit markets. The disease‐causing pathogens were identified utilizing molecular, microscopic, and morphological characteristics. Alternaria alternata and Aspergillus niger were identified as the pathogens responsible for brown rot in loquat and black rot in apricot. To combat these fruit diseases, iron oxide (Fe2O3) nanoparticles were synthesized using Bacillus subtilis and were characterized using various techniques. X‐ray diffraction examination validated the size of iron oxide nanoparticles. The presence of several capping agents in the synthesized nanoparticles was confirmed by Fourier transform infrared analysis. Scanning electron microscopy revealed the spherical morphology of nanoparticles, whereas energy‐dispersive X‐ray proved the presence of different elemental compositions. After completing antifungal activities in vitro and in vivo, it was discovered that a nanoparticle concentration of 1.0 mg/mL efficiently suppressed the growth of fungal mycelia. Fungi growth was effectively inhibited in fruit samples treated with 1.0 mg/mL nanoparticles. The results of successful in vitro and in vivo antifungal activities imply that iron oxide (Fe2O3) nanoparticles play an important role in ensuring fruit quality against pathogenic attacks. Bacterial‐mediated iron oxide can be widely used because it is less expensive and less harmful to the environment than chemically manufactured fertilizers.

“…8 In addition, the use of synthetic chemicals for extending shelf life and prolonging storage of horticulture commodities is restricted due to rising consumer concerns about both human health and the environment. As an alternative, several edible and antioxidant compounds which are approved as generally recognized as safe (GRAS) by the Food and Drug Administration of the USA have been frequently used as a pre-and postharvest treatment on persimmon fruit for suppressing ripening and improving fruit quality, including methyl jasmonate, 9 gibberellic acid, 10 calcium chloride, 11 1-methyl cyclopropane, 12,13 hydrogen sulfide and γ-aminobutyric acid; 14 also edible coatings such as gum arabic, 15 carboxymethyl-chitosan 16 and gelatin. 5 Recently, several findings have proved that fruit softening occurs due to the gradual breakdown of the cell membrane by direct catabolic cascades of phospholipase D (PLD) enzyme on the phospholipid bilayer; 17 cell membrane weakening is also enhanced by the generation of ROS during stress conditions such as cold storage and postharvest handling.…”

BACKGROUNDPersimmon (Diospyros kaki L.) fruit is characterized by rapid metabolic changes following ripening, and softening occurs due to the gradual breakdown of the cell membrane by direct catabolic cascades of phospholipase D enzyme on the phospholipid bilayer. Cell membrane weakening is also enhanced by the generation of reactive oxygen species during stress conditions such as cold storage and postharvest handling. This research evaluated the postharvest hexanal dipping application on persimmon fruit storage quality.RESULTSThe response of ‘MKÜ Harbiye’ persimmon fruit to exogenous hexanal at different concentrations (0.04% and 0.08%, named as HEX‐I and HEX‐II, respectively) on quality parameters, chilling injury (CI), microbial growth, antioxidant compounds and free radical scavenging capacity (FRSC) during storage at 0 °C and 80–90 ± 5% relative humidity for 120 days were evaluated. Both hexanal treatments retained quality and delayed senescence, as indicated by greener peel (lower a* and L* values), higher firmness, total phenol concentration, FRSC and titratable acidity, but lower weight loss, electrical conductivity, rate of CO2, ethylene production, decay and microbial growth than the control. Total soluble solids were lower in treated fruit than the control up to 100 days, and were much lower in HEX‐I treatment as compared to HEX‐II treatment. HEX‐I treatment exhibited lower CI than the other treatments during storage.CONCLUSIONHexanal at 0.04% could be used to increase the storage period of ‘MKÜ Harbiye’ persimmon fruit up to 120 days at 0 °C and 80–90 ± 5% relative humidity by retaining quality and delaying senescence. © 2023 Society of Chemical Industry.

“…In short, we found that exogenous MeJA promoted the activities of antioxidant enzymes under cold stress, and effectively mitigated the damage caused by cold stress to tea plants. Bagheri et al suggested that the MeJA application reduces the MDA content and REL level and improves the antioxidant enzymes’ activities, leading to significant decreases in the chilling injuries of persimmon [ 59 ].…”

Low-temperature stress is an increasing problem for the cultivation of tea (Camellia sinensis), with adverse effects on plant growth and development and subsequent negative impacts on the tea industry. Methyl jasmonate (MeJA), as a plant inducer, can improve the cold-stress tolerance in tea plants. R2R3-MYB transcription factors (TFs) are considered potentially important regulators in the resistance to cold stress in plants. However, the molecular mechanisms, by which MYB TFs via the jasmonic acid pathway respond to cold stress in the tea plant, remain unknown. In this study, physiological and biochemical assays showed that exogenous MeJA application could effectively promote ROS scavenging in the tea plant under cold stress, maintaining the stability of the cell membrane. Sixteen R2R3-MYB TFs genes were identified from the tea plant genome database. Quantitative RT-PCR analysis showed that three CsMYB genes were strongly induced under a combination of MeJA and cold-stress treatment. Subcellular localization assays suggest CsMYB45, CsMYB46, and CsMYB105 localized in the nucleus. Exogenous MeJA treatment enhanced the overexpression of CsMYB45, CsMYB46, and CsMYB105 in E. coli and improved the growth and survival rates of recombinant cells compared to an empty vector under cold stress. Yeast two-hybrid and bimolecular fluorescence complementation experiments confirmed that CsMYB46 and CsMYB105 interacted with CsJAZ3, CsJAZ10, and CsJAZ11 in the nucleus. Taken together, these results highlight that CsMYB45, CsMYB46, and CsMYB105 are not only key components in the cold-stress signal response pathway but also may serve as points of confluence for cold stress and JA signaling pathways. Furthermore, our findings provide new insight into how MYB TFs influence cold tolerance via the jasmonic acid pathway in tea and provide candidate genes for future functional studies and breeding.
