Sažetak
The mycovirus Cryphonectria hypovirus 1 (CHV-1) infects the ascomycete fungus Cryphonectria parasitica, the causal agent of chestnut blight, an introduced disease of Castanea sativa in Europe. CHV-1 reduces the virulence of C. parasitica against its host tree – a property used in the biological control of the pathogen. The hypovirus is transmitted between fungal strains of the same vegetative compatibility (vc) type, but only at reduced rates between strains of different vc types. The aim of this study was to test the efficiency of naturally occurring hypoviruses to infect virulent C. parasitica strains in the field. For this, a common field experiment was conducted in chestnut coppice forests in Switzerland, Croatia, and Macedonia. The main results of the experiment can be summarized as follows: (1) Natural hypoviruses infected virulent cankers of common vc types faster and more efficiently than cankers of rare vc types, (2) Hypovirus infection significantly reduced canker growth in Switzerland and Macedonia, but not in Croatia, and (3) Virus infection was associated with the immigration of new C. parasitica genotypes into the cankers. The study demonstrates that CHV-1 is an efficient natural biological control agent of chestnut blight in many regions of Europe.
