Summary: Grapevines infected with Grapevine red blotch virus (GRBV) produced grapes with lower sugar and anthocyanin content. While other parameters showed no significant differences, this infection affected grape ripening and wine quality.

Summary: This study characterized the volatile profile of Trincadeira grapes and investigated its changes under infection with Botrytis cinerea. The results showed that infected grapes had higher contents of ester acetates and lower contents of fatty acid esters. The up-regulation of a gene involved in volatile metabolism was also observed. These changes may impact the grape quality and defense against B. cinerea.

Summary: This study evaluated the effect of cold plasma treatment on the inactivation of Botrytis cinerea and preservation of grape quality. The results showed that short-time cold plasma treatment was effective in inhibiting gray mold and reducing microbial load. However, long-time cold plasma treatment caused tissue damage and decreased quality indicators. Overall, short-time cold plasma treatment can effectively inactivate B. cinerea and preserve grape quality.

Summary: Proteases are important in plant defense systems, playing crucial roles in establishing hypersensitive responses, priming, signaling, and recognition events through complex proteolytic cascades. However, the contribution of proteases to pathogen defense in grapevine remains poorly understood.

Summary: Machine Learning (ML) techniques are used to convert Big Data into valuable information for agri-environmental applications, such as predictive pest modeling. This study focuses on optimizing the Touzeau model, a correlation model between temperature and L. botrana development, using data-driven ML models. Field observations and 30 GB of weather data were combined to train the ML models and make predictions on pest flights. The results show that ML models outperform the Touzeau model, with the best-performing model being an artificial neural network with four layers.

Summary: This article provides an updated review of monitoring, modeling, and management tools for the European grapevine moth (EGVM), a primary pest of vineyards. It analyzes various management strategies, including insecticide-based control, insecticide resistance, side-effects of pesticides, cultural control, sterile insect technique, pheromone-mediated control strategies, biological control, and area-wide control programs. The article also outlines significant challenges for future research on EGVM and sustainable control implementation.

Summary: The European grapevine moth is a species that can feed on over forty plant species, but grapevine is its preferred crop globally. It has recently spread to Chile, Argentina, and California, and there are concerns about its possible further expansion in other regions of the Americas. In this study, we provide an updated review of its taxonomy, morphology, biology, ecology, genomics, geographic distribution, and invasiveness. We also outline significant challenges for future research on bio-ecology and invasion biology, which are crucial for prevention and management strategies.

Summary: This study used whole-genome resequencing to elucidate different aspects of the recent evolutionary history of grapevine, supporting a model in which a central domestication event was followed by postdomestication hybridization with local wild genotypes. The research found a strong introgression signature in modern wine varieties across Western Europe, with a subset of Iberian grapevine varieties showing large introgression tracts. The analysis demonstrated how regions under selection in wild populations from the Iberian Peninsula were preferentially passed on to the cultivated varieties through gene flow.

Summary: Understanding alternative pathogen control methods is crucial in organic phytosanitary management of vineyards. This study evaluated the efficacy of seven biofungicides and a novel fungicide composed of chitosan and riboflavin in preventing and treating Botrytis Bunch Rot (BBR) in grapevines. The biofungicides significantly reduced the growth of B. cinerea, but their effectiveness varied in different grapevine berries. Two biofungicides, Aureobasidium pullulans and Melaleuca alternifolia oil, showed high control effectiveness. The new experimental formulation CH-RF demonstrated promising results and warrants further research for B. cinerea control.

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: 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: The study compared the cold tolerance of different generations of European grapevine moth pupae and found that the third-generation diapausing pupae exhibited the highest levels of cold tolerance and the lowest supercooling point. The research suggested a relationship among supercooling point depression, cold tolerance enhancement, and diapause development.
