Summary: High endogenous SA is associated with low ET evolution and high SL, while high lycopene content is correlated with high SA levels. Total antioxidants, PG, and PME decrease with fruit development, while lipid peroxidation increases. SlPAL4 and SlPAL6 genes play significant but opposite roles in regulating fruit ripening.

Summary: Bioactive compounds and healthful nutrient-rich fresh fruits and vegetables play an important role in providing nutrition and promoting good health. Enzymatic browning caused by the activity of specific enzymes can negatively impact the appearance and nutritional value of these products. Various conventional and emerging techniques have been studied to inhibit enzymatic browning while minimizing quality attribute loss. This review examines the effectiveness of different techniques, the factors influencing browning inhibition, and the potential applications in fruits and vegetables.

Summary: Drought is a key threat to plants and agriculture, and the role of the enzyme phenylalanine ammonia lyase (PAL) in drought tolerance has been explored in this study. A PAL member called FuPAL1 was isolated from the alpine pharmaceutical plant Fritillaria unibracteata. FuPAL1 was found to play a role in the ammonization process and was involved in substrate binding and catalysis. Transgenic Arabidopsis plants with FuPAL1 showed increased levels of lignin and salicylic acid and enhanced drought tolerance. These findings suggest that FuPAL1 could be a valuable target for improving drought resistance.

Summary: The study revealed that PAL family genes in Rehmannia glutinosa are involved in the biosynthesis and release of several phenolics, and positively regulate the development of replanting disease. Overexpression of RgPALs in transgenic R. glutinosa increased phenolic production and allelopathic effects, exacerbating autotoxic harm.

Summary: Exogenous melatonin treatment improves cold resistance of mangoes, with 'Langra' mangoes showing the greatest benefit and 'Gulab Jamun' mangoes showing the least. The positive effect is associated with an increase in endogenous melatonin concentration, which prevents reactive oxygen accumulation and stimulates non-enzymatic antioxidants. 'Langra' mangoes also exhibit enhanced antioxidant activity and cold resistance enzyme performance.

Summary: Researchers cloned the cDNA of Rhodotorula glutinis PAL (RgPAL) and introduced codon optimization to enhance its protein expression and enzyme activity in Escherichia coli. This improvement allowed for the successful expression and purification of the recombinant enzyme PAL-opt, which exhibited high specific activity for substrate L-phenylalanine and L-tyrosine. This bifunctional enzyme provides a promising foundation for future applications.

Summary: Enzymatic browning is a major issue in postharvest quality loss for fruits and vegetables. There has been a shift towards natural antibrowning agents due to the demand for fresh-like products without chemical additives. Essential oils, hydrosols, honey, and plant extracts have gained attention for their ability to affect oxidative enzymes and act as membrane integrity promotors, substrate synthesis suppressors, and oxygen quenchers. However, challenges remain in their application, such as variability and lower effectiveness compared to synthetic agents, as well as strong odors and limited solubility for essential oils and hydrosols.

Summary: This study investigated the accumulation of flavonoids in Chinese sour jujube fruits from five different harvest times using a combined metabolomics and transcriptomics approach. A total of 1539 differentially accumulated metabolites (DAMs) and 11592 differentially expressed genes (DEGs) were identified. The biosynthetic pathways for flavonoids, flavones, and flavanols were significantly enriched. A regulatory network for flavonoids biosynthesis was built and key genes related to flavonoid biosynthesis were identified.

Summary: The study reveals the positive role of Ca2+ ATPase in litchi energy metabolism and senescence. Higher expression of LcACAs is associated with better storability in litchi cultivars. Additionally, LcACA2 is identified as a target of LcmiR482e and ATP application can downregulate the expression of LcmiR482e, contributing to delayed senescence in litchi.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.

Summary: This study evaluated a large set of blueberry cultivars to understand the relationship between mechanical texture and appearance characteristics at harvest and after storage, and tested multiple statistical models to predict shelf-life. The results showed that fruit characteristics measured at harvest or two weeks post-harvest can predict weight loss, texture change, and fruit wrinkling. These findings provide empirical data that blueberry breeders can use to select cultivars with extended shelf-life.

Summary: This study found that H2S treatment can delay the senescence process of postharvest pakchoi by regulating antioxidant system, endogenous H2S and NO metabolism. H2S increased the activities of antioxidant enzymes by up-regulating the expression of enzyme genes, reducing the accumulation of harmful substances. Furthermore, H2S increased the content of cysteine and nitrate in pakchoi by regulating the expression of related genes and enzyme activities, thus slowing down the senescence of pakchoi.
