Sažetak
In Europe, the mycovirus Cryphonectria hypovirus 1 (CHV-1) acts as a successful biological control agent of the chestnut blight fungus Cryphonectria parasitica. The hypovirus induces a hypovirulent phenotype by reducing parasitic growth and sporulation capacity of its fungal host. Hypovirulence is present in many chestnut-growing areas of Europe, either naturally or after biological control treatments. Studies of natural hypovirulence in C. parasitica populations over a period of more than 20 years revealed (1) a stable high prevalence of the hypovirus over time, (2) an equally stable diversity of fungal vegetative compatibility (vc) types, (3) no correlation between vc type diversity and CHV-1 prevalence, and (4) no differences in hypovirus diversity and virulence between fungal populations with high and low vc type diversity. The short-term dynamics of hypovirus infections was experimentally studied in chestnut forests with natural hypovirulence in North Macedonia, Croatia, and Switzerland. Cankers were artificially initiated with genetically defined, virus free C. parasitica strains and the developing cankers were repeatedly sampled over two growing seasons. Results showed that cankers initiated by common vc types became more efficiently hypovirus-infected than cankers initiated by rare vc types. Likewise, immigration of new C. parasitica haplotypes was more frequent in cankers of common vc types than of rare vc types. After two growing seasons, 70% of the cankers (between 61% to 81% per country) were hypovirus-infected. Most of these cankers showed a reduced growth compared to virus-free cankers demonstrating the efficiency of natural hypovirulence in these chestnut forests.
