Summary: This study investigated the effects of UV-C treatment on grape berries, showing that UV-C can promote the accumulation of phenolic components in grapes, thereby enhancing the application value of waste grapes. UV-C treatment at different developmental stages led to changes in grape berry appearance and sugar content, with the most significant effects seen in the veraison stage. UV-C also upregulated genes related to transcription factors, protein modification, and various plant hormones, suggesting its potential for improving the nutritional quality of grapes.

Summary: This study utilized transcriptomic data to establish a molecular phenology scale (MPhS) for tracking the development of grape berries. The MPhS accurately quantified the genetic distance between fruit samples and revealed the complex dynamics of the transcriptional program over berry development. It proved to be a complementary method for mapping grape berry development with higher detail compared to classic approaches based on time or phenotype.

Summary: The study evaluated the metabolite profiling and antioxidant activities of three muscadine grape genotypes at different berry developmental stages. A total of 329 metabolites were identified, with amino acids, organic acids, sugars, and phenolics as the dominant chemical groups. The metabolomics study revealed that developmental stages rather than genotypes explained variations in metabolic profiles, with certain compounds showing strong correlations with antioxidant activities.

Summary: This study investigated the physiological and molecular changes in resveratrol synthesis in grape berries under two levels of water stress. The results showed that water stress inhibited berry development but increased the content of total polyphenol and resveratrol. Enzymes and genes related to resveratrol synthesis played a role in regulating the changes. Water stress influenced the enzyme activities of PAL and STS, as well as the expression of genes such as VvMYB14 and VvMYB15.

Summary: The study examined the composition and concentration changes of VOCs in grape berry development among different accessions. Different patterns of VOCs production were observed, with total VOCs levels and aldehydes increasing during development. Monoterpenes, hydrocarbons, and ketones peaked at maturation stage, while alcohols, sesquiterpenes, and C13-noisoprenes were most concentrated at fruit-set.

Summary: Metal-free synthesis of highly functionalized (E)-stilbenes cored with electronic donor and acceptor functionalities was achieved through a carbanion-induced ring transformation reaction between (E)-4-(4-(dimethylamino)phenyl)but-3-en-2-one 12 and 6-aryl-2H-pyran-2-ones 9 in the presence of a base. The procedure has several advantages, including mild reaction conditions, readily available precursors, metal-free synthesis, simple setup, and the synthesis of various substituted regioselective (E)-stilbenes in good yields.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
