title: Detection of European mountain ash ringspot-associated virus-specific RNA and protein P3 in the pear leaf blister mite Phytoptus pyri (Eriophyidae).
abstract: The means by which European mountain ash ringspot-associated virus (EMARaV), a minus-strand ssRNA virus and the type member of the genus Emaravirus, is naturally spread, is unknown. In attempts to identify an EMARaV vector, galls induced by the eriophyid mite Phytoptus pyri were frequently found on infected leaves. By immunofluorescence microscopy, the presence of EMARaV nucleocapsid protein P3 was demonstrated in P. pyri individuals collected from diseased plants. Furthermore, RT-PCR analysis of entire P. pyri individuals revealed the presence of both viral genomic ss(-)RNAs and antigenomic ss(+)RNAs, suggesting that P. pyri might be a candidate vector of EMARaV.
