Summary: The study revealed that grape yield components are determined by complex polygenic factors, with certain SNPs showing additive effects on the phenotype. This suggests that superior grape cultivars with optimized fruit production can potentially be generated by pyramiding advantageous alleles from different genetic loci.

Summary: The balance between vegetative and reproductive growth in grapevines is crucial for grape quality and productivity. Field experiments showed that a decrease in sink availability significantly affected the physiological functionality of leaves, but only minimal effects were observed when only the grape bunches were removed.

Summary: Chimerism is the presence of multiple genotypes in a single individual, which has been used to understand plant development and is valuable in breeding new cultivars. The viticulture industry has benefited economically from chimeras, especially when they induce significant changes in wine characteristics. Chimeras that affect crucial agronomic traits, but have not been identified yet, are also important. The most stable type of chimera, periclinal chimera, can be propagated through cuttings. In this study, we used new generation sequencing, bioinformatics tools, and parental sequences to detect periclinal chimeras in 'Merlot' grapevine cultivar.

Summary: In perennial fruit species, such as grapevine, the phenomenon of somatic embryogenesis (SE) can lead to the formation of deformed embryos, for reasons that are still not well understood. In this study, the authors investigated cotyledonary embryos of grapevine cv. 'Chardonnay' with distinct morphologies to explore this issue. They found that normal cotyledonary embryos (NCEs) and elongated cotyledonary embryos (ECEs) had better-developed vasculature and shoot meristems compared to vitrified cotyledonary embryos (VCEs) and fused cotyledonary embryos (FCEs), but ECEs were less developed. The authors suggested that the morphological differences in these abnormal embryos were likely associated with changes in endogenous hormone levels, particularly indoleacetic acid (IAA) and abscisic acid (ABA). Comparative transcriptome analysis revealed significant differences in gene expression related to hormone signaling pathways in normal and abnormal cotyledonary embryos. Weighted gene co-expression network analysis identified co-regulated gene modules associated with SE, indicating the involvement of ERF family genes and other transcription factors (TFs) in regulating embryonic morphology. Furthermore, the authors found that specific protein kinases, small heat shock proteins (sHSPs), and TFs were closely associated with the formation of normal cotyledonary embryos. This study provides valuable insights into the genetic networks controlling cotyledon development during somatic embryogenesis, opening up new avenues for research on plant regeneration and functional genomics of malformed embryos.

Summary: Grapevine trunk diseases (GTDs) are complex and challenging to identify and eradicate. This study investigated the fungal community structure associated with GTDs symptomatic and asymptomatic grapevines. The results showed that symptomatic plants had a lower abundance but higher diversity of GTDs-associated fungi. The composition of fungal endophytic communities was significantly different according to the symptomatology and not affected by the cultivar.

Summary: In this study, yeast and bacterial isolates with antagonistic activity against Penicillium digitatum and P. italicum on citrus fruits were screened and identified. These isolates significantly reduced the incidence of green and blue mold caused by these pathogens on citrus fruits, and effectively prevented fungal infection during low-temperature storage. Moreover, they did not have any negative effect on fruit quality and shelf life. These selected isolates have multiple modes of action and show promise as biocontrol agents for postharvest green and blue molds of citrus fruits.

Summary: Fresh fruits and vegetables continue metabolic activity after harvest, leading to ripening, increased susceptibility to decay-causing fungi, and consequent loss and waste. Edible coatings can reduce waste, respect the environment, and benefit consumer health. They act as a protective agent, extending shelf life, and have the potential to control ripening and maintain nutritional properties of fresh produce.

Summary: Both chitosan (CTS) and chitooligosaccharide (COS) can regulate reactive oxygen species (ROS) homeostasis during wound healing of pear fruit by scavenging excessive H2O2 and improving antioxidant capacity. They increase NADPH oxidase and superoxide dismutase activities, promote O2.- and H2O2 production, enhance the activities of several enzymes, and elevate the levels of ascorbic acid and glutathione. In addition, they improve antioxidant capacity in vitro and maintain cell membrane integrity at fruit wounds. COS demonstrates superior performance over CTS.

Summary: Grapevines are a significant concern due to their potential risk to health and biodiversity. Therefore, it is crucial to control the distribution of agrochemicals to achieve high quality and sustainable viticulture. Field tests using a LIDAR-based prototype coupled with a commercial sprayer showed improved distribution performance and reduced incidences of grapevine diseases. This innovative sprayer, with its on/off control system, can effectively reduce chemical distribution and regulate vineyard fungal diseases, contributing to sustainable and high-quality production.

Summary: Postharvest fruit loss is caused by the absence of advanced handling and storage technologies and the presence of fungal pathogens. This study focused on the use of edible coatings derived from Origanum vulgare L. subsp. viridulum essential oil and Aloe arborescens Mill. gel to provide defense against fungal infections in papaya. The results showed that fruits coated with the combination of essential oil and gel had higher fungal contamination, while fruits coated with the hydrolate only showed better preservation of organoleptic characteristics with lower decay index. These findings suggest that the use of hydrolate can be a sustainable alternative to synthetic fungicides for extending the shelf life and maintaining the quality of papaya fruit.

Summary: This study found that preharvest chitooligosaccharide (COS) spray can alleviate chilling injury (CI) in muskmelon fruit by regulating membrane lipid metabolism and increasing antioxidant enzyme activity. The COS spray up-regulated the expression of CmPLA(2), promoting the release of unsaturated fatty acids and increasing the double bond index (DBI) value. It also down-regulated the expression of CmPLC and CmPLD, increased the levels of phosphatidylcholine (PC) and phosphatidylinositol (PI), and decreased the levels of phosphatidic acid (PA). Furthermore, the COS spray increased the activity of superoxide dismutase (SOD) and catalase (CAT), decreased O-2(-) and H2O2 levels, maintained cell membrane permeability, and reduced MDA levels in fruit during chilling, thereby alleviating CI.

Summary: This study tested the effectiveness of six natural compounds in controlling postharvest decay of strawberries. Chitosan-based coating compounds and citrus essential oil products were effective in controlling gray mold under cold storage conditions, while methyl jasmonate plant growth regulator and grapefruit seed essential oil products were more effective at room temperature. Humic acid and chitosan-based coating compounds were more effective in controlling Rhizopus rot under both cold storage and room temperature conditions.
