Summary: The karst carbon sink caused by rock outcrops affects the physiological processes of plants by enriching bicarbonate in the soil. This study compared the water use efficiency of Lonicera japonica and Parthenocissus quinquefolia under different rock outcrop habitats, and found that Lonicera japonica was more adaptable to karst environments.

Summary: The study introduced a new design strategy that endowed the adhesive with high-efficiency self-healing performance through abundant dynamic hydrogen bonds, and gave good mechanical properties to energetic composite materials (ECMs) by strong adhesion. The synthetic energetic adhesive could completely recover all mechanical properties within a short time after breaking at room temperature, indicating good energy level and promising applications in improving weapon system security.

Summary: Chemotherapy can have toxic effects on cancer treatment. Targeted drug delivery systems, such as hydrogels, play an important role in reducing treatment-related toxicities. In this study, a hydrogel was prepared using a plant extract as a crosslinker. The hydrogel showed high swelling behavior and in vitro biodegradability. It exhibited pH-responsive Doxorubicin release and demonstrated anticancer effects on breast cancer cell lines. This study suggests that the hydrogel has potential for combination and cancer therapy studies.

Summary: Detailed analysis of carrot pomace fiber remaining after commercial juice extraction revealed that enzyme-treated pomace contained branched, unsaturated, partially acetylated and methylated rhamnogalacturonan I (RG-I) with arabinogalacto-oligosaccharide side chains, as well as other oligosaccharides. Enzymatic treatment decreased molecular weight and increased water solubility of the fiber. Insoluble and total dietary fiber increased during the year, while soluble dietary fiber remained relatively constant. The structure of carrot pomace fiber changed between harvests and its susceptibility to enzymatic degradation increased. The diversity of RG-I structures was greatest in the enzyme-treated pomace harvested in September. These findings suggest that carrot pomace fiber has potential as a low viscosity food ingredient and may possess various health benefits.

Summary: This study elucidated the intracellular signaling pathways involved in macrophage activation by REP-I polysaccharide purified from radish leaves. REP-I enhanced the expression and secretion of immune-related factors in macrophages. The effects were mediated by phosphorylation of MAPK and NF-κB pathways, with different pathways involved in the secretion of different factors. The study also revealed the involvement of pattern recognition receptors in the effects of REP-I.

Summary: In this study, Zhang et al. (2022) used various techniques to investigate the role of KNAT3 and KNAT7 transcription factors in the synthesis of mucilage pectin in Arabidopsis. They identified a group of genes regulated by these factors that coordinate the formation of specific pectic domains.

Summary: The structure of REP-I, a polysaccharide fraction from radish leaves, has been determined to contain various monosaccharides, with RG-I as the main component. The main chain consists of repeating [->2)-Rhap-(1->4)-GalpA-(1->] linkages, and there are three side chains present. REP-I's immunostimulatory activity may be attributed to this RG-I structure.

Summary: In recent years, there has been increasing interest in RG-I pectin isolated by low-temperature alkaline extraction methods due to its significant health benefits. However, research on other applications of RG-I pectin is still limited. This study provides a comprehensive overview of the sources, extraction methods, fine structure, and various applications of RG-I pectin in physiological activities, emulsions, gels, etc. The review not only serves as a valuable reference for future research on RG-I pectin, but also offers essential insights for individuals new to this field.

Summary: We experimentally confirmed the possibility of creating composite protein-polysaccharide hydrogels as delivery vehicles for antitumor RNase binase. The gel matrix, based on non-degrading RG and fibrin, does not require cytotoxic chemical cross-linking agents or divalent cations. By encapsulating the therapeutic enzyme binase in liposomes made from uncharged lipids, its prolonged release with preserved activity can be achieved.

Summary: This study evaluated the cell adhesion of four cultivars of tomato fruit and analyzed the cell walls to determine the contribution of pectic and hemicellulosic polysaccharides to fruit softening and altered cell adhesion. The results showed that Heinz 1706 and Money Maker were harder than Micro Tom and Ailsa Craig at both green and red ripe stages. Additionally, it was found that the content and branching degree of RG-I were associated with increased cell adhesion and reduced cell wall porosity, thus maintaining fruit firmness.
