Summary: This study systematically studied the role of sulfur dioxide (SO2) in maintaining the quality attributes of grape rachis during shelf-life. Results showed that SO2 significantly inhibited rachis browning and affected endogenous phenolic metabolism and sulfur assimilation. SO2 treatment promoted the accumulation of major phenolic compounds and activated gene expression involved in sulfite assimilation, leading to the accumulation of sulfur-containing metabolites. This study provided evidence for the anti-browning effect of SO2 through the accumulation of flavanols and sulfur-containing compounds.

Summary: Nitric oxide (NO) delays rachis browning in postharvest table grapes by preventing water loss, reducing phenols accumulation, inhibiting PPO activity, and inducing POD activity. Additionally, NO down-regulates PPO1, up-regulates POD3, and affects the expression of PAL2 and PAL3 in grape rachis, ultimately improving freshness and extending shelf life.

Summary: Potent cardamom oil vapour was found to be effective in delaying browning, reducing disease, and preserving the quality of rambutans. Treatment with 5 μL/L cardamom oil resulted in decreased PPO and POD activities, high L*, low chroma, low BI value, and fewer disease-related browning incidents. The treated rambutans exhibited higher phenolic compounds and antioxidant potential, and could prevent browning and maintain physicochemical qualities for a longer storage period compared to the control group.

Summary: Sunburn is a physiological disorder that affects the visual and organoleptic properties of grapes, leading to decreased commercial value and yield. It can be classified into sunburn browning and sunburn necrosis, caused by excessive photosynthetically active radiation, UV radiation, and temperature. Grapes respond by activating antioxidant defense mechanisms and producing screening compounds.

Summary: Enzymatic browning during fresh cutting and storage affects the quality and commodity value of fresh-cut potatoes. Glutamic acid (Glu) treatments were found to significantly reduce the browning of potato pulp and shreds. The optimal concentration of 15 g/L Glu treatment for 4 minutes extended the shelf-life of fresh-cut shredded potatoes to 5 days at 2-4 degrees C. Further research revealed that Glu treatment inhibits polyphenol oxidase (PPO) activity and total phenolic content, and regulates amino acid metabolism to prevent potato browning.

Summary: Enzymatic browning is a major factor causing the decline in consumer acceptance of fresh-cut products. In this study, it was discovered that prohibitin (PHB) plays a role in the enzymatic browning process and suppressing PHB can alleviate the browning of fresh-cut potatoes. The inhibition of PHB was found to enhance antioxidant activity and inhibit the activation of polyphenol oxidase (PPO) in potatoes.

Summary: Through a multidisciplinary approach, the non-browning phenotype of the apple cultivar 'Majda' was found to be controlled by different concentrations of chlorogenic acid and the expression of the polyphenol oxidase (MdPPO) gene. Organic acids and glutathione were also involved in preventing oxidative browning. The higher antioxidant activity of 'Majda' was verified, making it a potential candidate for breeding non-browning apple cultivars.

Summary: The study revealed that increased ethylene levels lead to grape rachis degreening and reduced chlorophyll content, with the transcription factor VvERF95 playing a key role in regulating this process. VvERF95 was found to upregulate the expression of genes involved in chlorophyll degradation, such as VvPAO1, under the induction of ethylene, shedding light on the mechanism of ethylene-enhanced chlorophyll degradation in grapes.

Summary: Sweetpotato storage roots tend to become brown due to damage incurred during various processes. This study analyzed the browning mechanism in two sweetpotato genotypes, finding that the high content of phenolic compounds and the up-regulation of related genes for PPO and POD result in sweetpotato browning. The study provides valuable breeding materials and a theoretical basis for breeding browning-resistant sweetpotato varieties.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

The findings reveal that the chilling and heat requirements of the cultivars appear discontinuous, with overlaps or transition periods between the two phases. The warm mean temperatures occurring during the chilling period are the main determinant of the flowering of the studied cultivars.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
