Sažetak
Chestnut blight is a disease caused by the fungus Cryphonectria parasitica which can be controlled by Cryphonectria hypovirus 1, CHV1. In this study, three-lateral interactions of chestnut, fungus and hypovirus were studied. It was found that genotypes of the fungus and virus as well as chestnut genotype are important for successful biocontrol. Further, we found out that marrons, chestnut cultivars, are especially vulnerable to chestnut blight and recover with much lower frequency than naturally growing chestnut. However, there is a difference in susceptibility of naturally growing trees as well, and certain hypovirulent fungal strains harboring specific virus isolates are more or less efficient against disease depending on chestnut genotype. Furthermore, as opposed to previously published results that imply higher virulence of French than Italian CHV1 subtypes towards chestnut blight fungus, our results reveal that some virus isolates of Italian subtype have equal effect on fungal host as strong French isolate CHV1/EP713.
