Functional Role of RING Ubiquitin E3 Ligase VdBre1 and VdHrd1 in the Pathogenicity and Penetration Structure Formation of Verticillium dahliae.

ABSTRACT: Verticillium dahliae, a virulent soil-borne fungus, elicits Verticillium wilt in numerous dicotyledonous plants through intricate pathogenic mechanisms. Ubiquitination, an evolutionarily conserved post-translational modification, marks and labels proteins for degradation, thereby maintaining cellular homeostasis. Within the ubiquitination cascade, ubiquitin ligase E3 demonstrates a unique capability for target protein recognition, a function often implicated in phytopathogenic virulence. Our research indicates that two ubiquitin ligase E3s, VdBre1 and VdHrd1, are intrinsically associated with virulence. Our findings demonstrate that the deletion of these two genes significantly impairs the ability of V. dahliae to colonize the vascular bundles of plants and to form typical pe
