Summary: This study explores the potential of using high-pressure processing (HPP) and a natural kiwifruit pectin methylesterase inhibitor (PMEI) to produce cloud-stable orange-based juice during chilled storage. The addition of kiwifruit PMEI greatly improves the cloud loss caused by pectin demethylation. The results show that orange-kiwifruit mixed juice and kiwifruit puree maintain cloud stability throughout 28 days, while orange juice experiences cloud loss after 3 days.

Summary: Pectin is an important polysaccharide in plants that can be degraded by pectin methylesterase (PME) to release methanol. Butyrivibrio bacteria play a key role in pectin degradation and methanol production in the rumen. Studying the crystal structure and catalytic mechanism of PMEs has potential applications in reducing methane emissions.

Summary: Pectin modification and degradation are crucial for plant development, but the mechanisms behind it are not well understood. This study explored the function of pectin in early pollen development. By overexpressing the OsPME1 gene, which encodes pectin methylesterase, rice lines with reduced pectin methyl esterification were generated. These lines showed abnormal phenotypes in anther and pollen development, especially in the pollen mother-cell stage.

Summary: The study identified two novel enzymes, VdPG2 and VdPME1, from the fungal plant pathogen Verticillium dahliae, which play different roles in degrading pectin during pathogen attack on plants. These enzymes may induce plant defense responses by releasing different types of oligogalacturonides (OGs).

Summary: This study characterized the pectin methylesterase inhibitor gene family in seven Rosaceae species and identified three genes that regulate pollen tube growth in pear. Quantitative real-time PCR analysis revealed that these genes are increasingly expressed during pear pollen tube growth. The results suggest that pectin methylesterase inhibitor regulates pollen tube growth by changing the distribution of methylesterified pectin in the apex.

Summary: In this study, the combined treatment of calcium chloride and pectin methylesterase was found to be effective in maintaining the firmness and inhibiting weight loss of raspberry fruit during postharvest storage. The treatment maintained the structure of the cell wall and reduced the activities of cell wall-degrading enzymes. Moreover, it increased the content of chelate-soluble pectin and maintained free water content.

Summary: Cell wall mechanical strength is partially controlled by pectin methylesterification, which involves the action of pectin methylesterases (PMEs). In this study, the rupture of the lettuce endosperm cap during seed germination was shown to be caused by cell rupture rather than cell separation. The status of pectin methylesterification and PME activities changed during seed germination, with the endosperm cap having lower PME activities and higher pectin methylesterification compared to the radicle. Tissue-specific pectin methylesterification and PME activities were found to play a role in lettuce seed germination.

Summary: This study demonstrates the potential of graphitic carbon nitride nanosheets (g-C3N4 NSs) in alleviating cadmium (Cd) toxicity to soybean by promoting plant growth, reducing oxidative damage, and enhancing root cell wall (RCW) components to retain Cd and prevent its migration. g-C3N4 NSs also reversed Cd-induced chlorosis and improved photosynthetic efficiency in soybean seedlings.

Summary: Dicranopteris linearis is a hyperaccumulator plant of rare earth elements, and silicon plays a role in REE detoxification. The study found that Si supply can alleviate the damage caused by REE stress and increase the expression of pectin-related genes, pectin polysaccharide concentration, and methylesterase activity. Si-modified cell walls have higher REE retention capacity, and the [Si-pectin] matrix increases the accumulation capacity of pectin-REE. These findings lay the foundation for the development of phytotechnological applications using D. linearis in REE-contaminated sites.

Summary: Hydroponic experiments demonstrated that inoculation of arbuscular mycorrhizal fungi significantly improved the growth of rice under cadmium stress, while reducing cadmium accumulation in plants. The levels of pectin and hemicellulose in root cell wall increased after fungal inoculation, along with higher lignin content. Further research is needed to understand the mechanisms of cadmium fixation in root cell wall components.

Summary: A variety of useful microorganisms, including Metschnikowia pulcherrima, live on the surface of grapes. This particular yeast secretes a beta-glucosidase that can release aromatic compounds during fermentation processes. The synthesis of an exocellular beta-glucosidase was demonstrated in this study, and the optimal conditions to maximize its effectiveness were determined. The enzyme showed high activity at 28 degrees C and pH 4.5, as well as tolerance to glucose, fructose, ethanol, and methanol. Furthermore, its activity was enhanced by calcium ions and low concentrations of ethanol and methanol. The impact of terpene content in wine was also investigated. Due to these characteristics, beta-glucosidase is a promising candidate for use in enology.

Summary: Beta-glucans are polymeric dietary fibers used as thickeners, stabilizers, and fat substitutes in foods. Their functional and technological properties depend on their origin, molecular weight, and structure, which can be influenced by various physical treatments. In addition to their technical qualities, beta-glucans have numerous beneficial impacts on human health, such as cholesterol lowering and hypoglycemic effects for people with type 2 diabetes mellitus (T2DM). This paper provides insights into the properties of beta-glucans and the effects of different treatments, as well as reviewing the latest research on beta-glucans as a functional ingredient for T2DM.

Summary: This study evaluated the effect of fertilization techniques and grafting on polyphenol oxidase (PPO) activity and colorimetric parameters in cultivated eggplants. Fertilization alone significantly increased PPO activity, while fertilization combined with grafting decreased PPO activity. There was a significant positive correlation between PPO activity and the a* values of the eggplants. Additionally, eggplant slices exposed to room temperature for 60 minutes showed a significant increase in PPO activity and color parameters.

Summary: Chlorophylls, responsible for the green color in plants, have high antioxidant activity and potential health benefits, including anti-inflammatory, anti-cancer, and anti-obesity properties. The by-products from food production, rich in chlorophyll content, can be considered environmental pollutants if not utilized as a source of bioactive compounds. This paper discusses the stability of chlorophylls under different treatments and reviews the latest research on their extraction from a sustainable perspective.

Summary: In this article, the link between regular wine consumption and human health is explored. The concept of regular wine consumption originated from Alvise Cornaro's teachings in the 16th century, where he advocated for wine to be consumed regularly. Wine played a central role in medieval society, being consumed in large quantities and used as a medicine. While moderate wine consumption has been linked to health benefits, any level of alcohol intake is now recognized as harmful. The modern wine industry is addressing this issue by producing wines with reduced alcohol content. However, wine continues to be consumed for pleasure and its social role.

Summary: This study evaluated the antioxidant activity and inhibitory effects on enzymes related to non-communicable diseases of white and red spent grape pomace (SGP), as well as the impact of storage on these bioactivities. The results showed that some of the bioactivities were not preserved after distillation, but improved after 1 month of storage. The phenolic profile remained stable during storage while the inhibition of α-glucosidase (AG) was enhanced. These findings confirm the remaining bioactivity of SGP, demonstrating its potential use in the food industry.
