BASIDIN as a New Protein Effector of the Phytopathogen Causing Witche's Broom Disease in Cocoa.

The fungus secretes protein effectors that manipulate the physiology of the host plant, but few effectors of this fungus have had their functions confirmed. We performed functional characterization of a promising candidate effector of . The inoculation of rBASIDIN at 4 µmol L in the mesophyll of leaflets of caused symptoms of shriveling within 6 h without the presence of necrosis.
