Biochemical characterization of wood decay and metabolization of phenolic compounds by causal fungi of grapevine trunk diseases.

ABSTRACT: Grapevine trunk diseases, such as Esca, Botryosphaeria dieback, and Eutypa dieback, are caused by various Ascomycota and Basidiomycota fungi that colonize wood and form internal lesions. Basidiomycota fungi, such as Fomitiporia species, are associated only with the trunk disease Esca, and are wood-decay fungi. Variation in the extent of lesion development among the fungal pathogens reflects a combination of fungal virulence and host susceptibility. To evaluate factors that may affect lesion development, we compared in vitro wood-decay abilities and tolerance of host secondary metabolites (cell-wall and soluble phenolic compounds) of four fungi that cause trunk diseases: Eutypa lata (Eutypa dieback), Fomitiporia polymorpha (Esca), and Diplodia seriata and Neofusicoccum parvum (Botryosphaeri
