Cereal yellow dwarf virus RPV - (CYDV-RPV)
This virus was previously regarded as a strain/serotype of the Barley yellow dwarf viruses (BYDVs), but is now assigned to the Cereal yellow dwarf viruses in the genus Polerovirus. It is widely distributed and infects cereals as well as grasses, in particular wheat, oats and barley. Like the other viruses resembling the BYDVs, the symptoms are characterized by yellowing and dwarfing. Characteristically, the flag leaf is also yellow. The virus can cause epidemics, resulting in significant losses. Planting resistant cultivars is the most common management option for the disease.
As indicated by the ending "RPV", CYDV-RPV is mainly transmitted by the aphid Rhopalosiphum padi in a persistent, circulative, non-propagative manner. It has been also referred to the "Rhopalosiphum padi virus". However, there is an insect pathogen with the same name, an unrelated picorna-like virus (from the family Dicistroviridae), see the Rhopalosiphum padi virus (entomopathogen).
