Abstract
High-throughput sequencing of two trees with apple decline revealed the presence of three bunya-like viruses: apple rubbery wood-associated viruses 1 and 2 (ARWaV-1, ARWaV-2) and citrus concave gum-associated virus (CCGaV), which previously had only been observed in citrus trees. The apple and citrus CCGaV isolates shared over 97% sequence identity. A global collection of apple trees was screened by RT-PCR for these viruses. Twenty-seven of 30 trees were infected with one or more bunya-like virus. Sequence data revealed some diversity among isolates but no geographic grouping. Additional work will be needed to determine if any of these viruses contribute to apple decline.
