Histopathological investigations on roots naturally diseased by infection with Ganoderma boninense suggest that the fungus is a vascular pathogen. Infection of the xylem vessels preceded the appearance of the pathogen in surrounding cells. The pathogen caused severe plugging of the vessels which may account for the symptoms of impairment of water uptake in infected palms. No evidence of a host reaction by formation of tyloses to restrict fungal movement was observed in infected vessels. The pathogen was not tissue specific and was present in all tissue types at the advanced stage of pathogenesis

Abstract

Histopathological investigations on roots naturally diseased by infection with Ganoderma boninense suggest that the fungus is a vascular pathogen. Infection of the xylem vessels preceded the appearance of the pathogen in surrounding cells. The pathogen caused severe plugging of the vessels which may account for the symptoms of impairment of water uptake in infected palms. No evidence of a host reaction by formation of tyloses to restrict fungal movement was observed in infected vessels. The pathogen was not tissue specific and was present in all tissue types at the advanced stage of pathogenesis
