‘Tuogu’ and ‘Bingtang’ plums display unique textural responses to salt curing, manifesting in volume reduction, surface wrinkling, and alterations in color and texture, alongside ongoing material exchange. Over a seven-day salting period, ‘Tuogu’ plums lost 14.9 % of their moisture, compared to ‘Bingtang’ plums' 24.8 %, with salt permeability rates of 5.0 % and 5.2 %, respectively. Cuticle analysis revealed that the dominant component of the cutin monomers in both fruits was fatty acids, accounting for over 90 %, while the wax composition was predominantly very long-chain alkanes and triterpenoids, also constituting over 90 %. ‘Tuogu’ plums, with their rich waxes and dense, thick cuticle, showed enhanced barrier properties against material exchange, whereas ‘Bingtang’ plums, with their abundant cutin monomers, exhibited increased elasticity and material exchange capacity.

The current work aimed to evaluate the efficacy of four coating formulations—chitosan coating (CH), 0.5% cinnamaldehyde + chitosan (0.5% CI–CH), 1.0% cinnamaldehyde + chitosan (1.0% CI–CH), and 1.5% cinnamaldehyde + chitosan (1.5% CI–CH)—on fresh mandarin fruit cv. Ponkan quality maintenance (weight loss, decay rate, total soluble solids, titratable acidity, vitamin C, color index, malondialdehyde, and antioxidant activity) over 100 days of storage at 20 °C. Compared to the control, chitosan treatment effectively reduced the decay and weight loss rates of mandarin fruit cv. Ponkan during storage at room temperature, delayed the decline of nutritional quality in fruits, increased the antioxidant capacity, and inhibited the accumulation of malondialdehyde (MDA). In comparison to chitosan coating, 1.5% CI–CH did not improve the fruit storage effect, but inhibited the normal color change of fruits and increased the accumulation of MDA. Both 0.5% CI–CH and 1.0% CI–CH effectively reduced the rate of fruit decay, improved the quality of fruits after harvest, and delayed fruit aging. Our study suggests that 0.5% CI–CH and 1.0% CI–CH might be good formulations for maintaining the quality of mandarin fruit cv. Ponkan during room-temperature storage.Keywords:chitosan;coating;cinnamaldehyde;fruit;room temperature

In kiwifruit ( Actinidia arguta ), fruit coloration is typically accompanied by ripening; however, the intrinsic connection between these two processes remains unclear. In this study, we found that ethylene and auxin accelerated and suppressed fruit coloration and ripening, respectively, in A. arguta . ETHYLENE INSENSITIVE 3-LIKE 2 (AaEIL2) and ETHYLENE RESPONSIVE FACTOR (AaERF059) were mined and identified using yeast two-hybrid library screening and transcriptome analysis. AaEIL2, specifically induced to high expression by ethylene, was confirmed as a transcription factor that positively regulates coloration and ripening by targeting AaLDOX (leucoanthocyanidin dioxygenase involved in anthocyanin biosynthesis) and AaPG18 (polygalacturonase involved in cell wall degradation) based on its subcellular localization in Arabidopsis protoplasts, stable genetic transformation in transgenic tomato, and yeast one-hybrid and luciferase activity assays. AaERF059 also responds to ethylene and regulates ethylene-/auxin-mediated fruit coloration and ripening by targeting the downstream genes AaACS2 (ACC synthase, which is involved in ethylene biosynthesis) and AaGH3 (Gretchen-Hagen 3, which is involved in the auxin pathway). Overall, AaEIL2 and AaERF059 regulate ethylene-and auxin-mediated fruit coloration and ripening by maintaining a dynamic balance in a positive and negative regulatory manner. Our results not only identified key genes but also established an intrinsic connection between fruit coloration and ripening in A. arguta .

Recent progress showed the potential of glutamate to regulate stress responses by affecting phytohormones homeostasis , but much remains to be explored. To decipher the role of ethylene in glutamate-induced resistance to Alternaria alternata , ethephon application, ethylene perception inhibitor (1-MCP) experiment and ethylene measurement were pursued. Concurrently, temporal alteration in ethylene biosynthesis and signaling pathways were transcriptionally analyzed in tomato fruit. Our data exhibited that ethylene conferred tomato fruit susceptibility rather than resistance to Alternaria alternata . The enhanced resistance in glutamate treatment was related to decreased ethylene production during the early stages of interaction, accompanied by lower expression levels of SlACS1 , SlACS2 and SlACO1 relative to the control. Interestingly, 1-MCP induced amounts of resistance similar to that observed in glutamate treatment, while ethylene receptors ( SlETR3 and SlETR4 ), mitogen-activated protein kinase SlMPK3 and ethylene response factor SlERF1 were down-regulated by glutamate during infection. Collectively, antagonizing the ethylene biosynthesis or signaling might play a pivotal role in glutamate-induced resistance to the necrotrophic pathogen Alternaria alternata .

As a traditional cash crop with ecological and nutritional values, mulberry is gradually expanding its consumption worldwide due to its great regional adaptability and superior health functions. The widespread interest in nutrients has led to a growing need to explore in depth the health benefits of mulberries. Many studies are actively being conducted to investigate the adaptability of the diversity of mulberries in different applications. This study systematically investigated the physicochemical properties and antioxidant activity of four mulberry genotypes cultivated in China’s semi-arid sandy regions to better understand the composition and health-promoting potential of this super crop. Chemical composition identification was identified via HPLC and antioxidant activity was further determined via DPPH and FRAP. The moisture, crude protein, ash, soluble solids, phenolics, anthocyanins, and flavonoids contents of mulberry were comparatively analyzed. The study revealed that the four mulberry genotypes showed significant differences in quality and content of the analyzed characteristics. The greatest antioxidant activity was found in Shensang 1, which had the most soluble solids (17%) and the highest amounts of free sugar (fructose: 5.14% and glucose: 5.46%). Ji’an had the most minerals (K: 2.35 mg/g, Ca: 2.27 mg/g, and Fe: 467.32 mg/kg) and it also contained chlorogenic acid, which has the potential to be turned into a natural hypoglycemic agent. PCA and Pearson correlation analysis indicated that the antioxidant activity was closely related to the chemical contents of total phenols, flavonoids, anthocyanins, and soluble sugars. If the antioxidant activity and nutrient content of the developed plants are considered, Shen Sang 1 is the most favorable variety. This finding can be used to support the widespread cultivation of mulberries to prevent desertification as well as to promote the development of the mulberry industry.Keywords:mulberries fruit characteristics;total phenolics;antioxidant activity

5-Aminolevulinic acid (5-ALA), an eco-friendly plant growth regulator, has been increasingly applied to crop and fruit production. In the actual production, many fruits are often covered by plastic bags which will not be removed until the fruits are harvested. Therefore, although 5-ALA shows promotive effect on fruit quality, fruit spray cannot be implemented in the orchards using plastic bags. In this study, rhizospheric application of 5-ALA increased the endogenous 5-ALA content in the leaves and fruits, suggesting that 5-ALA is transported from roots to aboveground. Using a multiple plant efficiency analyzer (M-PEA), we also found that rhizospheric application of 5-ALA significantly improved PS II and PS I photosynthetic activities of apple leaves. It means that 5-ALA-treated apple trees might accumulate more assimilates for fruits to improve their quality. Meanwhile, rhizospheric application of 5-ALA obviously increased fruit weight, the content of flavonoids, total soluble solids and ascorbic acid, as well as activities of antioxidant enzymes. Most importantly, rhizospheric irrigation of 5-ALA also significantly improved fruit coloration. Using calli induced from the flesh of ‘Fuji’ fruits, we found that 5-ALA up-regulated the expressions of many genes involved in flavonoid anabolism. These results suggest that rhizospheric application of 5-ALA solution is effective to improve external and interior qualities of apple fruits although 5-ALA was not directly applied to fruit surface. Taken together, we conclude that rhizospheric application of 5-ALA can be transported to the leaves and fruits of apple trees, where it enhances leaf photosynthetic capacity and improves fruit coloration and interior qualities simultaneously. This finding provides an effective and handy method to improve apple quality in modern orchards.

Ethylene is an essential indicator of fruit ripening and climacteric or non-climacteric nature. This study investigated the postharvest behavior of five Chinese bayberry cultivars ‘Biqi’, ‘Dongkui’, ‘Fenhong’, ‘Xiazhihong’, and ‘Shuijing’. The fruits were harvested mature and stored at room temperature (25 °C) and under cold storage conditions (4 °C) to investigate the dynamics of ethylene production, firmness, anthocyanin content, and cell wall polysaccharide composition, as well as basic fruit physicochemical characteristics. The results show that Chinese bayberry is a climacteric fruit with ethylene production peaking shortly after harvest, especially at room temperature. Fruit color intensified over time due to anthocyanin accumulation, particularly in the flesh core. Darker cultivars produced more ethylene, which correlated with higher anthocyanin levels. At room temperature, ‘Biqi’ (black) had the highest ethylene production (4.03 µL·kg−1·h−1) and anthocyanin content (0.91 mg/g FW), while ‘Shuijing’, the white cultivar, had the lowest ethylene levels (1.9 µL·kg−1·h−1) and anthocyanin content (0.03 mg/g FW). Firmness significantly decreased at room temperature due to the degradation of hemicellulose and insoluble pectin, whereas cold storage mitigates this effect. After 3 days at room temperature, the average of firmness decreased by 23.7% in the five cultivars, compared to 12.7% under cold storage. Total soluble solids increase during storage, enhancing sweetness, especially at room temperature, with ‘Biqi’ increasing from 9.2 to 10.9% at 4 °C. Titratable acidity slightly decreased over time: the value for ‘Biqi’ decreased from 1.2% to 0.95% at room temperature and 1.1% at 4 °C. Citric, malic, and tartaric acid generally declined at room temperature but stabilized under cold storage. Sucrose, fructose, and glucose increased or remained stable, with significant varietal differences. Our results indicate that storing Chinese bayberry at 4 °C effectively preserves its quality and extends postharvest life. These findings underscore ethylene’s key role in regulating ripening, postharvest quality, and shelf life by influencing fruit color, firmness, and overall consumer appeal.

Strawberry is a soft fruit with short postharvest life, due to a rapid loss of firmness. Pectin methylesterase (PME)-mediated cell wall remodeling is important to determine fruit firmness and softening. Previously, we have verified the essential role ofFvPME38in regulation of PME-mediated strawberry fruit softening. However, the regulatory network involved in PME-mediated fruit softening is still largely unknown. Here, we identified an R2R3-type MYB transcription factor FvMYB79, which activates the expression level ofFvPME38, thereby accelerating fruit softening. During fruit development,FvMYB79co-expressed withFvPME38, and this co-expression pattern was opposite to the change of fruit firmness in the fruit of ‘Ruegen’ which significantly decreased during fruit developmental stages and suddenly became very low after the color turning stage. Via transient transformation, FvMYB79 could significantly increase the transcriptional level ofFvPME38, leading to a decrease of firmness and acceleration of fruit ripening. In addition, silencing ofFvMYB79showed an insensitivity to ABA-induced fruit ripening, suggesting a possible involvement ofFvMYB79in the ABA-dependent fruit softening process. Our findings suggest FvMYB79 acts as a novel regulator during strawberry ripening via transcriptional activation ofFvPME38, which provides a novel mechanism for improvement of strawberry fruit firmness.Keywords:fruit softening;strawberry;FvMYB79;FvPME38

Panax notoginseng is highly used in traditional Chinese medicine, and its root is valued for ginsenoside contents. However, evidence suggests that other plant parts such as fruit, leaves, and stem are also potential sources of bioactive compounds. Therefore, this study aimed at providing insight into the differential accumulation of metabolites in fruit, leaf, root, and stem tissues collected from P. notoginseng. A total of 808 metabolites from 11 major metabolite classes were identified. Furthermore, 32 Ginsenosides with six conserved Ginsenosides Rg1, Rf, St-3, R1, Ro, Rc, and five conserved notoginsenosides R1, K, M, E, Rb1, were identified with differential accumulation in fruit, leaf, stem, and root tissues. Several other metabolites known for their potential roles in human health were also identified as differentially accumulated in the tissues. Furthermore, the accumulation pattern of ginsenosides in different tissues is highly suggestive of utilizing fruit, leaf, and stem tissues along with roots for value addition of P. notoginseng.

Sodium dehydroacetate (SD) and sodium silicate (Na 2 SiO 3 ) are food preservatives with antifungal activities against many pathogens. In this paper, the antifungal activity of the combination treatment of SD and Na 2 SiO 3 against Geotrichum citri-aurantii , the postharvest pathogen of sour rot in citrus fruit, was tested. SD and Na 2 SiO 3 combination (1:4, w/w) showed a synergistic inhibitory effect compared to single compound on the mycelial growth of G. citri-aurantii , with the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) being 1.8 and 3.6 g L −1 , respectively. The spores’ germination and the plasma membrane integrity of the pathogen could also be visibly influenced by the 1× MFC SD + Na 2 SiO 3 treatment. The application of various SD + Na 2 SiO 3 concentrations (1×, 5×, and 10× MFC) to citrus fruit inoculated with G. citri-aurantii significantly ( P < 0.05) decreased the incidence of sour rot during the entire storage period. After 8 d of storage, the disease incidences in SD + Na 2 SiO 3 (10×, 5× or 1× MFC)-treated fruit were only 20%, 30%, 65%, respectively, in contrast to 100% of the control fruit. Meanwhile, SD + Na 2 SiO 3 treatments maintained the fruit quality of citrus fruit. Results indicate that the combination of SD and Na 2 SiO 3 is a promising approach in controlling the postharvest decay of citrus fruit.

The red color of the foliage and fruit in strawberry comes from anthocyanins stored in the vacuole; however, how this anthocyanin accumulation is regulated remains unclear. A reduced anthocyanin in petioles (rap) mutant was identified in an N-ethyl-N-nitrosourea (ENU) mutagenized population of YW5AF7, a white-fruited variety of the wild strawberry Fragaria vesca. The causative mutation was identified to be a premature stop codon in a glutathione S-transferase (GST) gene. In addition to the foliage coloration, RAP also mediates fruit pigmentation and acts downstream of the fruit-specific transcription factor FvMYB10. Among all eight GST genes in the same subfamily, RAP is most abundantly expressed in the ripening fruit. Expression analysis and transient expression assays demonstrated that RAP is the principal transporter of anthocyanins among the paralogs. Moreover, domain-swap experiments showed that both the N- and C-terminals of RAP are essential for the binding capability of anthocyanins. In addition, transient knock-down of RAP resulted in reduced fruit coloration in cultivated strawberry. Collectively, our results demonstrate that RAP encodes the principal GST transporter of anthocyanins in the strawberry foliage and fruit, and it could be modified to alter the fruit color in strawberry.

The development of wound periderm is vital to prevent water vapor loss and pathogen invasion in wounded fruit. The effect of abscisic acid (ABA) on wound-healing in harvested tomato fruit was evaluated in this study. Wounded tomato fruit were treated with ABA or fluridone (FLD, an inhibitor of ABA biosynthesis), respectively, and allowed to wound-heal at 20 °C in darkness for 4 days. Weight loss of tomato fruit reflected the intuitionistic effects of different treatments during wound-healing. Autofluorescence and histochemical staining demonstrated the development of suberized wound periderm in harvested tomato fruit at 3–4 day after wounding. Alkanoic acids, n -alkanes, unsaturated fatty acids and pentacosane represented the major components in the suberin. ABA-treated fruit showed enhanced autofluorescence, histochemical intensity and suberin deposition along with increased activities of phenylalanine ammonia-lyase (PAL) and peroxidase (POD). FLD treatment, however, alleviated the features of suberization and enzyme activities during wound-healing. The results suggest that ABA is involved in the stimulation of wound-induced suberization in harvested tomato fruit.
