Ultrathin sections of diseased tissue contained enveloped, filamentous virus-like particles that measured 64 nanometers by 126-4000 nanometers. These lengths are unique for plant viruses. Unexpectedly, the spider mite, Petrobia letens, which has never been reported to be a vector of a pathogen, was found totransmit the causal agent from diseased plants to healthy barley, while noninfective mites failed to do so unless they were allowed prior access to diseased tissueCollection: AGRIS Collection
