A Coumarin Compound Derived From Zanthoxylum avicennae Reduces the Pathogenicity of Fusarium verticillioides by Directly Binding to and Inhibiting Glycoside Hydrolase 3 Activity

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Luvangetin, a coumarin compound from Zanthoxylum avicennae roots, affects the cell wall degradation capacity and pathogenicity of Fusarium verticillioides on maize. Integrated transcriptomic, proteomic and in vitro activity analyses revealed that it binds to three critical sites of the Fusarium glycoside hydrolase 3 family (GH3) β‐glucosidase ...
