Persistence of Cryphonectria hypovirus 1 in Cryphonectria parasitica might be affected by the transfer between the different vegetative compatibility types of the host
Phytopathogenic fungus Cryphonectria parasitica, causing agent of chestnut blight, severely devastated sweet chestnut forests in Europe. This fungus is a host of the virus Cryphonectria hypovirus 1, which is a natural biocontrol agent of this pathogen. Hyphal anastomosis is a frequent way of virus transmission between fungal strains. The persistence of anastomosis is regulated by vegetative compatibility (vc) system of the fungus. The most efficient virus transmission occurs between mycelia of the same vc type, but it becomes difficult between mycelia that belong to different vc types. In laboratory conditions, we transferred various virus strains into various fungal isolates belonging to different vc types. The persistence of the virus in the acceptor mycelia was determined by vc types of both, the virus‐donor and virus‐acceptor mycelia in cases when they belonged to different vc types. We hypothesize that the loss of the virus is caused by unsuccessful adaptation of the virus to the new host of different vc type. These in vitro results do not necessarily implicate similar scenario in the natural conditions, but they support observation in nature, where it was found that calli (healed cankers formed under the influence of hypovirulent fungus) often lose viruses with time.
