Abstract excerpt
The high mutation rates of RNA virus replication generate genetically diverse virus variants in infected hosts. However, the effects of mutations on viral fitness and adaptability remain understudied in fungal-virus pathosystems. In this study, a novel hypovirus (single-stranded positive-sense RNA genome, family Hypoviridae), designated Valsa pyri hypovirus 1-α (VpHV1-α), and two of its shorter, less prevalent...
