Summary: This study evaluates the use of a bio-based laser-perforated and recyclable SO2-generating liner, alone or in combination with ultra-fast SO2-generating pads, to extend the shelf life of 'Benitaka' table grapes. Results showed that the combination of bio-based and SO2-generating liners, along with ultra-fast SO2-generating pads, effectively controlled gray mold incidence after 45 days of cold storage and 3 days at room temperature. This extended the shelf life of the grapes with low weight loss, fewer shattered berries, and maintained stem freshness.

Summary: This study investigates the effects of gibberellin and cytokinin on the size and composition of grapes, as well as their subsequent impact on wine attributes. The results show that these plant growth regulators can increase berry diameter and weight, but also reduce sugar accumulation and color development. Furthermore, they affect the levels of flavan-3-ols, flavonols, anthocyanins, proanthocyanidins, and fatty acid derived volatile compounds in the berries, ultimately influencing the phenolic composition of the resulting wine.

Summary: Grapevine co-products, specifically canes, are a promising source of compounds that can effectively control vineyard diseases in a sustainable manner. A study was conducted on an extract produced from grapevine trunk and roots, which was enriched in complex stilbenes. The extract demonstrated strong inhibition of mycelial growth and spore germination of the fungal agent causing gray mold. The most active stilbenes identified were resveratrol, r-viniferin, and ??-viniferin.

Summary: This study analyzed transcriptomic data from healthy, noble rot, and grey rot grape berries collected in the Tokaj wine region in Hungary. The results showed that B. cinerea was most active in noble rot berries, followed by grey rot and healthy berries. The expression profiles also differed qualitatively between noble rot and grey rot, with several functional genes linked to physico-chemical changes in botrytized grape berries.

Summary: The study found that changes in phenolic compounds, such as flavonols, were most significant in wines made from grapes exposed to a combination of UV-A and UV-B radiation, whereas wine VOCs showed less pronounced reactions to UV exposure. These results provide new possibilities for manipulating UV radiation in grapevine cultivation to improve grape and wine quality.

Summary: The regulated deficit irrigation (RDI) in grapevines can enhance the quality of berries and wine by increasing phenolic compounds, particularly proanthocyanidins (PAs). Skin PAs content increased under RDI, especially in RDI-1 and RDI-2, while seed PAs content was less affected. Different irrigation levels at RDI-2 and RDI-3 can significantly impact PAs composition, influencing wine astringency perception.

Summary: The use of elicitors such as methyl jasmonate and methyl jasmonate n-doped calcium phosphate nanoparticles can increase the amino acid composition in Monastrell grapes and wines, with MeJ-ACP showing better results compared to MeJ despite using less quantity. This application form could be used as an alternative for more efficient and sustainable agriculture.

Summary: In order to combat Botrytis cinerea disease in grapevines, beneficial bacteria with antimicrobial properties were isolated from vineyard soil, screened for their effectiveness, and found to contain biocontrol-related genes that could potentially be used as a biocontrol agent in harvested grapevines.

Summary: Grape produces a variety of secondary metabolites, primarily regulated by uridine diphosphate-glycosyltransferases (UGTs). Different groups of VvUGT members may be involved in the synthesis and accumulation of various compounds, impacting the development and ripening of grape fruits.

Summary: Stilbenes are natural phenolic compounds synthesized by plants in response to stress. They are found in grape berries and wine, with potential anti-obesity effects. Optimized analytical methods are essential for accurate detection and quantification of stilbenes.

Summary: An irrigation trial conducted in the Karst region showed that a deficit irrigation regime of 20% ETC led to a significant increase in both total and extractable anthocyanin concentrations in grapes, along with a higher degree of galloylation in proanthocyanidins. These findings may contribute to enhancing the potential quality of wine.

Summary: Studies have shown that fruit-zone leaf removal affects the microclimate of grapevine growth and has complex effects on fruit composition. This study analyzed the volatile profiles of Cabernet Sauvignon grapes exposed to leaf removal at different phenological stages over three years. Leaf removal, especially before flowering, increased total soluble solids and phenols in the grapes. The concentration of amino acid-derived and isoprene-derived volatiles was higher in grapes with leaf removal before flowering compared to after flowering or at veraison. This research lays the groundwork for further studies on optimizing Cabernet Sauvignon aroma and breeding in vineyards.

Summary: This study investigated the early response of grapevine to Esca pathogens and identified metabolites that may be associated with the biocontrol activity. The results showed that glycerophospholipids and polyphenol compounds, particularly stilbenoids, may play a role in limiting the development of Esca pathogens in planta. In vitro evaluation also demonstrated antifungal activity of some relevant biomarkers against Phaeomoniella chlamydospora and Botrytis cinerea.

Summary: This study presents the first comprehensive identification of proteome content from a white wine (cv. Silvaner). By using mass spectrometry-based proteomics, the wine protein composition was identified through in-solution and in-gel digestion methods after size exclusion chromatographic fractionation. A total of 154 characterized or uncharacterized proteins mainly from Vitis vinifera L. and Saccharomyces cerevisiae were identified, providing valuable information for wine authentication and understanding of organoleptic properties and stability.

Summary: The study compared the antifungal activity of different bacterial biological control agents against Botrytis cinerea, finding that Bacillus velezensis BUZ-14 strain performed the best while commercial biocontrol products showed less efficacy. Additionally, the culture medium of the strains significantly influenced their antifungal efficacy against the pathogen.

Summary: Contamination of grape berries by Botrytis cinerea can damage wine quality, with consumers increasingly reluctant to accept SO2 addition. Oenological tannins have colloidal properties and can stabilize wine color, with antioxidant and antioxidasic effects. Proanthocyanidin tannins from grape skin were found to have protective effects against laccase oxidation at a 20% botrytised rate.

Summary: Grapevine decline, a major issue in viticulture, is difficult to understand due to its multifactorial nature. This study focuses on the indicators of yield, mortality, and vegetative vigour to propose diagnostic indicators for grapevine decline. The findings suggest that fluctuations in yield and vegetative vigour indicators are earlier indicators of decline compared to yield loss. The study also proposes easy-to-obtain indicators using ground-based NDVI and aerial photograph analysis. These findings provide a better understanding and promising tools for early diagnosis of grapevine decline.

Summary: Despite increasing studies on biocontrol of grapevine trunk diseases, no commercial bacterial products have been developed yet. Understanding the modes of action and application methods for biocontrol agents is crucial for success. Different bacterial strains show potential in controlling Neofusicoccum parvum through various mechanisms, including secretion of antifungal compounds and induction of systemic defenses in grapevines.
