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 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 conducted QTL mapping for grape gray mold resistance based on two hybrid offspring populations. Two stable QTL related to gray mold resistance were detected on the LG2 and LG7 chromosomes. Through RNA sequencing, a structural gene VlEDR2 and three transcription factors VlERF039, VlNAC047, and VlWRKY51 were identified as potential candidates involved in VlEDR2 expression and grape gray mold resistance. These candidate resistance genes will provide an important theoretical reference for future research and breeding of gray mold-resistant grape cultivars.

Summary: The essential oil from Nepeta meyeri has been shown to have allelopathic effects on gray mold, potentially serving as a biofungicide in vineyards. Specifically, applying a 1 ppm solution of EO at a concentration of 1.0 mu L/leaf one day before inoculation resulted in the most significant prevention of fungus development on the leaves.

Summary: Grapevine trunk diseases (GTDs) pose an increasing threat to grape production worldwide. Different grape cultivars show varying degrees of susceptibility to GTDs. A study on Hungarian grape germplasm collections found that Vitis vinifera L. cultivars were more sensitive to GTDs compared to interspecific hybrids containing other Vitis species in their pedigree. The ancestral diversity of grapes confers greater resilience against GTDs.

Summary: Recent studies have shown that moderate iron stress can increase the concentrations of volatile organic compounds associated with floral notes in wines, while decreasing the presence of C6-alcohols responsible for green herbaceous aromas. Wines from iron deficient subzones showed a favorable reduction in pH and improvements in color-related parameters. The incidence of chlorosis was associated with enhancements in wine sensory attributes such as layer intensity, black fruit, and aroma intensity.

Summary: The study demonstrated that using rare sugar-based products can induce resistance in grapevine leaves against downy mildew, primarily through enhancing the activation of salicylic acid- and jasmonic acid/ethylene-responsive genes and stilbene phytoalexin accumulation. IFP48 provides protection against P. viticola infection, but shows inconsistent effects against B. cinerea.

Summary: This study surveyed the occurrence of eight grapevine viruses in commercial vineyards in the Calchaquies Valleys in Argentina. The results showed that 60% of the samples were infected with some of the viruses, with GLRaV-3 and GFLV being the most common.

Summary: Grapevine red blotch disease, caused by grapevine red blotch virus (GRBV), has affected vine stock production and vineyard profitability in North America. This study reveals that the insect vector Spissistilus festinus can transmit GRBV between different grapevine hybrids and grape cultivars, highlighting the interconnected roles of virus hosts in riparian areas and commercial vineyards. The findings have important implications for disease management strategies.

Summary: In order to cultivate different grape varieties according to market needs, it is important to study the regulation mechanism of color changes in grapes at different development stages. This study used RNA-sequencing technology to compare and analyze the transcriptome data of four grape varieties at the same development stage. The anthocyanin synthesis pathway in the flavonoid pathway was mainly studied among the annotated differential genes. The role of the MYB transcription factor MYB2 in anthocyanin regulation was confirmed through subcellular localization and gene function verification.

Summary: The study found that feeding immature herbage in combination with vine leaves reduces methane yield in dairy cows, but high urinary nitrogen losses associated with this feeding strategy need to be addressed.

Summary: Ethylene can stimulate plant respiration and generate heat. The experiments showed that by spraying ultra-low concentrations of ethylene precursors onto grapevines prone to poor fruit set, the fruit set can be improved and crop losses can be reduced.

Summary: This study evaluated the effects of diets containing vitiviniculture waste on intake, digestibility, water balance, nitrogen balance, ingestive behavior, performance, and carcass traits of lambs. The results showed that feeding lambs with diets containing 216 g/kg cactus pear and 144 g/kg vitiviniculture waste resulted in higher intake and digestibility.

Summary: Transcriptomics and metabolomics are increasingly used in molecular studies of grapevine to understand plant and fruit development, as well as interactions with the environment. Integrating these methods can help improve fruit quality and stress resistance in breeding programs. Despite generating vast amounts of data, integrated transcriptome/metabolome meta-analyses have not been fully accomplished in this species due to specificities of metabolomic studies.

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.
