- Abstract
A potyvirus tentatively named Ornithogalum virus 3 (OV-3) was successfully isolated by single-aphid transmissions from O. thyrsoides mix-infected with OV-3, Ornithogalum mosaic virus (OrMV) and Ornithogalum stripe mosaic virus (OrSMV). OV-3, a flexuous, rod-shaped particle of ca. 690 nm, was sap and aphid transmissible. The virus had a narrow host range and caused necrotic mosaic on O. thyrsoides under cold conditions. We therefore propose the name Ornithogalum necrotic mosaic virus (OrNMV) for OV-3. A synergistic increase in symptom severity was apparent on O. thyrsoides mix-infected with OrSMV/OrNMV, but not with either OrMV/OrNMV or OrMV/OrSMV.
