Prenylated Isoflavonoids-Rich Extract of Erythrinae Cortex Exerted Bone Protective Effects by Modulating Gut Microbial Compositions and Metabolites in Ovariectomized Rats.

Flavonoids, found in a wide variety of foods and plants, are considered to play an important role in the prevention and treatment of osteoporosis. Our previous studies demonstrated that Erythrina cortex extract (EC) rich in prenylated isoflavonoids exerted bone protective effects in ovariectomized (OVX) rats. The present study aimed to investigate the interactions of gut microbiota with the EC extract to explore the underlying mechanisms involved in its beneficial effects on bone.

Functional Characterization of the Novel Laminaripentaose-Producing β-1,3-Glucanase GluB and Its Biocontrol of .

Fungal cell wall synthesizing enzymes or remodeling enzymes represent key factors for the interaction of plant pathogen and antifungal agents, which are regarded as potential biocontrol agents. In this study, a novel endo-β-1,3-glucanase from was expressed and characterized. The expression of GluB was significantly upregulated after 2 days of liquid culture and 48 h after infection, indicating that it may be involved in cell wall reconstitution.

Preparation of Active Chitooligosaccharides with a Novel Chitosanase CoA and Their Application in Fungal Disease Protection.

Enzymes that degrade fungal cell walls and the resulting oligosaccharides are promising weapons to combat plant fungal disease. In this study, we identified a novel endo-chitosanase, CoA, from sp. A7-Y.

Identification and fine-mapping of a genetic locus underlying soybean tolerance to SMV infections.

Soybean mosaic virus (SMV) is a major pathogen causing yield loss. Developing soybean plants tolerant or resistant to SMV is important for mitigating the adverse effects of the viral infection. However, most studies have focused on the resistance to normal SMV strains.
