Summary: This study found that Hyp-O-polysaccharides isolated from transgenic Arabidopsis suspension culture have similar structural features to AGPs isolated from tobacco. It also confirmed the presence of a previously identified β-1,6-linkage on the galactan backbone in AGP fusion glycoproteins expressed in tobacco. Furthermore, AGPs expressed in Arabidopsis suspension culture have differences in terminal-rhamnosyl residues and glucuronosylation compared to those expressed in tobacco suspension culture, suggesting the presence of distinct glycosyl transferases and minimum AG structures for type II AG functional features.

Summary: The emulsifying capacity (EC) of proteins, measured by a sudden drop in electrical resistance with the addition of oil to a protein solution, is influenced by protein concentration. A linear relationship was found between conductivity and final protein concentrations, indicating conductivity's sensitivity to protein electrolytes. The conductivity test described allows for accurate determination of protein EC, and may be used by the food industry to compare emulsifying properties of protein ingredients.

Summary: Arabinogalactans (AGs) are structural polysaccharides of the plant cell wall, associated with proteins forming arabinogalactan proteins (AGPs) that play important roles in plant growth, cellular differentiation, signaling, and microbe interactions. In beneficial plant-microbe interactions, AGPs attract symbiotic fungi or bacteria, promote infectious structure development, and activate plant defense mechanisms. Pathogenic and beneficial fungi and bacteria can produce enzymes to degrade AGs from AGPs, impacting plant-microbe interactions.

Summary: This study investigated the role of proteins and polysaccharides in the bioleaching of spent coin cells (SCCs). The results showed that both proteins and polysaccharides play an important role in the bioleaching process, with proteins mainly concentrated in tightly bound EPS (TB-EPS) and polysaccharides in loosely bound EPS (LB-EPS). The binding rate of Mn and Li to EPS was positively correlated with the protein and polysaccharide content, and the principal functional groups involved in Mn and Li binding were O-H and carboxyl.

Summary: To ensure high-quality water, toxic pollutants must be removed. Currently, various sorbents are used for water purification. Modified polysaccharides are efficient sorption materials. This study presents a new environmentally friendly method for modifying larch hemicellulose-arabinogalactan with polybasic carboxylic acids to obtain composite materials. The synthesized derivatives were characterized using various physicochemical methods, and it was found that the modified samples had promising potentials as drug carriers, sorbents, and water treatment agents due to their high sorption capacity and developed mesoporous surface.

Summary: The Sphaeralcea angustifolia plant is used in Mexican traditional medicine for its anti-inflammatory and gastrointestinal protection properties. Scopoletin, tomentin, and sphaeralcic acid have been identified as the compounds responsible for the immunomodulatory and anti-inflammatory effects of this plant. Hairy roots from S. angustifolia were explored for biosynthetic stability and capacity to produce new compounds, and they were found to produce scopoletin, sphaeralcic acid, stigmasterol, beta-sitosterol, iso-sphaeralcic acid, and 8-methyl-iso-sphaeralcic acid. The extract from SaTRN7.1 hairy root line showed a gastroprotective effect on an ulcer model in mice induced with ethanol.

Summary: This review focuses on the origin of coffee, its agroindustrial position in Mexico and the world, and its biological effects on human health. Coffee originated in Ethiopia and was used in Arab countries as food and a fermented beverage for its stimulating effect. The Coffea genus comprises more than 100 species, with C. arabica and C. canephora being the most well-known. Commercially, C. arabica is the main variety for production and consumption, while C. canephora is mainly used as a base for instant coffee. The main consumers are the United States and countries of the European Union, with Brazil and Vietnam being the main producers. Mexico ranks tenth in coffee production, with Chiapas as the major producer and Guerrero known for its organic and specialty coffee. Coffee beans contain phenolic compounds, such as chlorogenic acids and caffeine, which contribute to its aroma, bitterness, and astringency. The main biological effects of chlorogenic acids are antioxidant, anti-inflammatory, and antidiabetic, while caffeine is a neurostimulator.

Summary: This study established in vitro cultures from B. karatas seeds and determined their total phenolic content. Different scarification treatments were tested to promote seed germination. The seeds were also cultured on MS media containing different concentrations of BA and 2,4-D. The results showed that exposing the seeds to H2SO4 resulted in a higher germination percentage. In vitro cultures significantly reduced the germination time compared to field data. The highest callus induction percentage was obtained in adult specimens and plants germinated in vitro in MS media containing BA and 2,4-D. The phenolic content was highest in mature fruits of B. karatas, while the lowest was recorded for callus and leaves of in vitro seedling. These findings contribute to programs for the sustainable use and conservation of this ethnobotanically important species.
