Phytopathogenic fungi normally secrete large amounts of CWDEs to enhance infection of plants. In this study, we identified and characterized a secreted glycosyl hydrolase 5 family member in (SsGH5, Glycosyl Hydrolase 5). was significantly upregulated during the early stages of infection. Knocking out did not affect the growth and acid production of but resulted in decreased glucan utilization and significantly reduced virulence. In addition, expressing SsGH5 became more susceptible to necrotrophic pathogens and basal immune responses were inhibited in these plants. Remarkably, the lost virulence of the mutants was restored after inoculating onto transgenic . In summary, these results highlight that suppresses the immune responses of through secreting SsGH5, and thus exerts full virulence for successful infection.

Antarctic snow harbors diverse microorganisms, including pigmented algae and bacteria, which create colored snow patches and influence global climate and biogeochemical cycles. However, the genomic diversity and metabolic potential of colored snow remain poorly understood. We conducted a genome-resolved study of microbiomes in colored snow from 13 patches (7 green and 6 red) on the Fildes Peninsula, Antarctica.

Natural products and their derivatives are precious resources with extensive applications in various industrial fields. Enzymatic glycosylation is an efficient approach for chemical structure diversification and biological activity alternation of natural products. Herein, we reported a stereoselective glycosylation of complex natural product glycosides catalyzed by two carbohydrate-active enzymes (CAZys).

is the causative agent of Chagas disease, a neglected tropical disease, and one of the most important parasitic diseases worldwide. The first genome of was sequenced in 2005, and its complexity made assembly and annotation challenging. Nowadays, new sequencing methods have improved some strains' genome sequence and annotation, revealing this parasite's extensive genetic diversity and complexity.

Phenylethanoid glycosides (PhGs) are widely occurring secondary metabolites of medicinal plants with interesting biological activities such as antioxidant, anti-inflammatory, neuroprotective, antiviral, hepatoprotective, immunomodulatory, etc. They are characterized by a structural core formed by a phenethyl alcohol, usually tyrosol or hydroxytyrosol, attached to β-D-glucopyranose via a glycosidic bond. This core is usually further decorated by attached phenolic acids or another saccharide.

The antifungal targets of the new fungicide -(naphthalen-1-yl)-phenazine-1-carboxamide (NNPCN) are still incomplete, limiting its application. To identify potential new targets of NNPCN and facilitate target hunting, a suite of techniques was employed to conduct experiments on . Nine potential targets were identified, exhibiting strong binding affinity to NNPCN, as indicated by binding free energies below -100.
