![]() parasitica is not clarified and could be also exert its function together with other enzymes such those of the glyoxylate cycle that have been found to be involved in the virulence of Candida (Lorenz and Fink 2001). However the biological function of laccase in the virulence of C. parasitica containing the European type of dsRNA. Many reports (Mayer, 1987 Rigling, Heiniger, Hohl 1989 Rigling, Alfen 1991 1993) suggested that transmissible hypovirulence may be associated with laccase production in the fungus as it was reported that laccase production is reduced in hypovirulent strains of C. Knowledge of the vc types and their geographic distribution in an area are crucial for successful application of biological control (Anagnostakis et al. Many vegetative compatibility (vc) types have been recorded in Europe (Bissegger et al., 1997 Robin et al. Hypovirus has a cytoplasmatic origin and the transmission of hypovirulence from strain to strain of the fungus is restricted by a genetic system of vegetative compatibility. The method is widely applied in many European countries. The application of a hypovirulent strain around developing lesions may enable these lesions to recover and can convert the virulent strain into a hypovirulent strain. In the past, this fungus had a great impact on the European chestnut (Castanea sativa Mill.) and on the American chestnut (Castanea dentata (Marsh.) Borkh.) completely devastating American chestnut forests.Hypovirulent strains of the fungus occur in nature due to infection of the fungus with a double-stranded RNA virus and they are used for a natural disease control. The fungus forms a canker and attacks the stem and branches of chestnut, progressively weakening the tree and resulting in death of branches or entire tree. The Asian fungus Cryphonectria parasitica is mainly found on members of the Fagaceae and well known as the chestnut blight fungus (Adamíková et al.
