Transmission of Cryphonectria Hypovirus 1 (CHV1) to Cryphonectria radicalis and In Vitro and In Vivo Testing of Its Potential for Use as Biocontrol Against C. parasitica.

ABSTRACT: Cryphonectria hypovirus 1 (CHV1) is successful in controlling Cryphonectria parasitica, the causal agent of chestnut blight, but little is known regarding its transmission to other fungi, for example the European Cryphonectria radicalis. In this study, CHV1 was transmitted (circa 200,000-800,000 copies/microliter) to seven C. radicalis isolates from infected C. parasitica. Reverse transmission to virus-free C. parasitica (European 74 testers collection) was achieved, although it was less successful (250-55,000 copies/µL) and was dependent on the vegetative compatibility (VC) group. In C. radicalis, the virus infection led to colony colour change from pink to white and smaller colonies, dependent on the virus concentration. The virus was concentrate
