Summary: The influence of regulated deficit irrigation on the anthocyanin composition in Cabernet Sauvignon grape skins was investigated. Mild water stress had slight effects on the composition in different seasons, but the accumulation patterns were similar. Different irrigation treatments did not induce a greater accumulation of one or another type of anthocyanin.

Summary: A method utilizing microwave-assisted extraction for extracting phenolic compounds from grape seeds and skins was developed and optimized, leading to stable conditions for extraction. The repeatability and intermediate precision of the method were found to be excellent based on the results obtained.

Summary: In this study, the researchers identified SnRK2s as important regulators in grape berry development and resistance against B. cinerea in strawberries. Specifically, VvSnRK2.2 and VvSnRK2.7 promoted fruit ripening, while VvSnRK2.3 and VvSnRK2.6 enhanced resistance against B. cinerea.

Summary: Rainfall under continental climates with monsoonal tendency affects the microbial niches in vineyards during grapevine growth. Cultivation under rain-shelter may alter the microbial community and impact vine traits. This study found that rain-shelter cultivation reduced fungal and bacterial diversity, with differences observed in microbial patterns between different growth stages.

Summary: This study investigated the extraction of polyphenolic compounds from grape pomace and their antioxidant capacities. The compounds were found to be retained on polyvinylpolypyrrolidone and showed inhibitory activity against certain pathogenic microorganisms. These findings have important implications for the development of new industrial processes and by-products, promoting a circular economy.

Summary: Microbiota succession in the fermentation of Cabernet Sauvignon under rain-shelter cultivation differed from that under open-field cultivation, with a decrease in fungal diversity and changes in dominant fungi and bacteria. The abundance of certain fungal species was positively correlated with the production of esters and higher alcohols. Fungal community succession, rather than bacterial microbiota, showed a positive correlation with the final wine volatiles under rain-shelter cultivation.

Summary: Global warming affects secondary metabolism of grape berries, and the review summarizes the structure, biosynthesis, and degradation mechanisms of grape berry secondary metabolites. Abiotic factors such as temperature and water availability influence the secondary metabolism and quality of grape berries.

Summary: Despite partial understanding, the role of green tissues in fruits, such as tomatoes and red grapes, is not fully known. This study analyzed enriched organelle fractions from grape skin chloroplasts and evaluated the expression of key genes in berry skins and leaves to explore isoprenoid and lipid metabolism. The findings suggest that grape skin chloroplasts, like leaf chloroplasts, share conserved mechanisms in synthesizing and degrading important components of the photosynthetic machinery, which play a crucial role in grape and wine sensory characteristics.

Summary: Severe shoot topping (SST), a viticultural technique, was studied for three years (2018-2020) to investigate its impact on vine physiology, berry sugar accumulation rate, and flavoromics of Cabernet Sauvignon grapes in a semi-arid climate. Results showed that SST treatments caused a reduction in grape sugar accumulation without affecting yield. Photosynthetic compensation was observed in SST-treated vines across vintages. SST grapes had lower concentrations of berry skin anthocyanins and flavanols, but higher concentrations of certain flavonols. A minor influence of SST on aroma compounds was observed, which appeared to be vintage-dependent. The study provides a viticultural strategy to address climate change in semi-arid regions.

Summary: This study evaluated the impact of grapevine red blotch disease (GRBD) on agronomical parameters of 'Cabernet Sauvignon' vines at harvest using metabolomics approach. The results showed that GRBD influenced degrees Brix, berry weight, primary and secondary metabolites in both skin + pulp/flesh and seeds. The effectiveness of 1D H-1 NMR and RP-HPLC in quantifying impacted metabolites was compared and the most affected metabolites in each tissue were identified.

Summary: Moderate consumption of red wine has been associated with the prevention of cardiovascular diseases, with phenolic compounds playing a key role in the cardioprotective effects by inhibiting platelet aggregation, modulating the lipid profile, and promoting vasorelaxation. The antioxidant capacity of these compounds also helps prevent ROS generation and LDL oxidation. Specific phenolic compounds like resveratrol and quercetin are linked to promoting NO production and inhibiting platelet aggregation, albeit at concentrations lower than those found in red wines. Synergic and additive effects of a mix of phenolic compounds contribute to the overall cardioprotective effects observed in red wine and its byproducts.

Summary: Monoterpenes play a significant role in grape and wine aroma. The study revealed that bound monoterpenes biosynthesis is repressed during the rainy season, and rain-shelter cultivation can enhance the content of monoterpenes in grapes and wines, improving tolerance to rain-induced stresses.

Summary: This systematic review focuses on the phenolic profiles of grape, juice, and wine, as well as the potential benefits of their consumption on the human microbiota. It highlights the possibility of exploring a new research area based on the synergy between polyphenol consumption and microbiota, and emphasizes the urgent need for strategies to improve the bioavailability of these compounds.

Summary: IBD refers to inflammatory conditions that disrupt the bowel and involve the immune system, often associated with colorectal cancer. Grape by-products, rich in bioactive compounds, have shown promising effects in reducing inflammation, oxidative stress, and cancer cell proliferation in both in vivo and in vitro studies.
