Rhopalosiphum padi virus (RhPV) is a member of ''
Dicistroviridae'' family, which includes
cricket paralysis virus (CrPV), ''Plautia stali'' intestine virus and
''Drosophila'' C virus. Its
5'UTR
The 5′ untranslated region (also known as 5′ UTR, leader sequence, transcript leader, or leader RNA) is the region of a messenger RNA (mRNA) that is directly upstream from the initiation codon. This region is important for the regulation of t ...
region contains an
internal ribosome entry site (IRES) element with a cross-kingdom activity. It can function efficiently in mammalian, plant and insect translation systems.
Testing of R. padi aphids collected from different sites in Sweden revealed the presence of RhPV in wild aphid populations for the first time in Europe. Virus could be detected in several life stages of R. padi, including sexual individuals and eggs, establishing an over-wintering route for the virus.
