Summary of R. padi transmission and virion detection following membrane feeding of different cereal yellow dwarf virus-RPV preparations used for RT-PCR and TEM evaluations.

aPurified virus that was used for RT-PCR and TEM analysis was tested for transmissibility using aphid transmission assays. Number of plants infected/total number of plants inoculated; total percent infection indicated.bNumber of aphids with detectable amount of viral RNA/total number of aphids tested.cNumber of aphids with virus in the HG cell/total number of aphids evaluated.
