Summary: The fruit agribusiness sector in Colombia, particularly avocado and mango, plays a significant role in terms of area planted and volume exported. Improving productivity, quality, and postharvest life of these fruits is crucial due to high losses. Biostimulants offer a potential solution to enhance fruit productivity and quality. This study evaluated the effect of preharvest application of biostimulants on yield and quality of avocados and mangos, showing positive results without compromising postharvest quality.

Summary: The study found that fruit size and weight decrease during cold storage, respiration rate and color variables differ between different maturity stages, and levels of soluble carbohydrates and organic acids vary with fruit maturity. Most amino acids decrease during cold storage, but some increase in 100% mature fruits.

Summary: The ripening behavior and role of ethylene in blueberry fruit are complex and controversial. This study investigated the changes in respiration and ethylene production, as well as the expression of related genes, in blueberry fruit during ripening. The results suggest that blueberry fruit display climacteric ripening behavior and functional ethylene signaling.

Summary: The objective of this study was to investigate the effects of temperature on ethanol vaporization rate and uptake rate of fruit species and cultivars, as well as the relationship between temperature, ethylene metabolism, and respiration rate of fruit. The study also aimed to evaluate the impact of temperature on the metabolites produced by fruit in response to ethanol treatment. The results showed that ethanol vaporization rate increased exponentially with temperature and had a linear relationship with time. Temperature and fruit species/cultivar influenced the ethanol uptake rate, with the highest uptake rate observed at 20 degrees C. Ethanol vapor uptake rate was positively correlated with respiration rate, indicating that fruit metabolism affects ethanol uptake rate. The temperature also affected the metabolites produced by fruit in response to ethanol treatment, with different patterns observed in different fruit species.

Summary: Germs associated with insect eggs play a crucial role in mediating interactions between host plants and herbivores. In this study, it was found that the egg-associated germs induced defensive responses in tomato, resulting in increased levels of tannins, flavonoids, amino acids, and salicylic acid. The presence of lactococcus sp., brevundimonas sp., and vagococcus sp. bacteria were responsible for these effects. The presence of tannins and flavonoids had negative effects on the pupal biomass of the oriental fruit fly, while metabolome analysis revealed that the fly mainly induced metabolic changes in carboxylic acid derivatives.

Summary: This study investigated the changes in ROS and their scavenging systems during nectarine fruit development and ripening and found a complex reprogramming of ROS-related transcriptome and metabolome. The activation of specific ethylene response factors and the accumulation of antioxidant compounds were observed at earlier fruit developmental stages, while a decrease in respiration rate and reduction of ERF1 genes led to higher accumulation of H2O2 at later stages. The study suggests that H2O2 may not only be a by-product of ROS-scavenging but also a signaling molecule during nectarine fruit ripening.

Summary: This study investigated the effects of 1-MCP on the postharvest storage of different varieties of pomegranate fruit. The results showed that 1-MCP treatment reduced peel browning and weight loss in soft-seed pomegranates. Furthermore, 1-MCP improved the color, texture, and sensory quality of the fruit. Therefore, 1-MCP has significant potential for use in postharvest preservation of pomegranates.

Summary: This study evaluated the chilling injury symptoms in soursop fruit when stored at low temperatures. The results showed that soursops stored at 9 degrees C did not develop normal color and firmness, while those stored at 14 degrees C behaved similarly to the control group. Additionally, soursops stored at 9 degrees C for 8 days showed substantial decreases in respiration, ethylene production, electrolyte leakage, and flavonoid content, while total phenolics increased.

Summary: The effects of 9-D1t-PhytoP on platelet activation and vascular cells were tested, along with possible interactions with platelets and the endothelial EP3 receptor. The results showed that 9-D1t-PhytoP has prothrombotic and wound-healing properties, and mimics the migration stimulus of PGE(2) in endothelial cells. Computational analysis revealed its potential as an EP3 agonist by forming a stable complex with the EP3 receptor.

Summary: Kitul (Caryota urens L.) inflorescences are widely used for sweet sap production in Asian countries and have potential antidiabetic properties. In this study, the methanol extract of the inflorescences was shown to reduce reactive species in pancreatic cells and inflammatory markers in stimulated macrophages. The extract also inhibited 5-lipoxygenase activity. These findings suggest that Kitul inflorescences may have pleiotropic mechanisms as an antidiabetic agent.

Summary: The by-products of grape winemaking process, such as grape stems, pomace, and wine lees, contain a diverse range of phytochemical compounds, notably polyphenols, which have health benefits. However, these by-products have negative impacts on the sustainability of the agro-food industry and the local environment. This study compares the polyphenolic profiles of these three residues and provides new knowledge on the role of yeast and lactic acid bacteria metabolism in diversifying the phenolic composition. The results show that grape stems have the highest diversity of polyphenols, followed closely by wine lees. Yeasts and LAB may play a key role in transforming phenolic compounds, resulting in new molecules with specific bioactivity features and improving the biological potential of these underexploited residues.

Summary: This study aimed to investigate the effects of exogenously foliar-applied salicylic acid (SA) on oxidative stress in rice. The concentrations of PhytoPs and PhytoFs in immature and mature grains of three different genotypes of rice were monitored, and their influence on grains per panicle and chalkiness was examined. The results showed that SA reduced oxylipin levels and increased rice yield.

Summary: Heat and nutritional stresses have a significant impact on the accumulation of harmful compounds in green leafy vegetables. The inoculation of plant growth-promoting bacteria (PGPB) combined with optimal nitrogen (N) levels under heat shock conditions can result in healthier and higher yielding crops. The results showed that overfertilization with 20 mM N was not beneficial, but reducing N levels and inoculating plants under heat stress improved productivity and increased the content of beneficial compounds.

Summary: In this study, Lavandula latifolia was subjected to drought stress and the antioxidant defense system was analyzed. The researchers found that the physiological parameters of the leaves changed under drought conditions and the response of the antioxidant defense to drought varied depending on the plant type. The concentrations of most polyphenols decreased, but rosmarinic acid showed some drought resistance. These findings provide valuable information for the selection of drought-tolerant cultivars.

Summary: Wine-making byproducts have negative impacts on the environment and industrial sustainability, but they can be utilized as sources of bioactive compounds. This study found that wine lees contain a high concentration of alkyl gallates, and the drying process reduces their concentration to some extent. Freeze-dried grape stems and pomace showed strong radical scavenging capacity and α-glucosidase inhibitory activity. These findings suggest potential valorization alternatives for these winery residues.
