Isolation and characterization of a novel potyvirus tentatively named Ornithogalum virus 2.

摘要

A novel potyvirus, tentatively named Ornithogalum virus 2 (OV-2) because only its nucleotide sequence of the coat protein gene has been revealed, was isolated for the first time from Ornithogalum thyrsoides. OV-2 had a flexuous particle (700-740 nm in length) and was sap and aphid transmissible. The virus had a narrow host range; of 36 test plants in 12 families, only O. thyrsoides and O. dubium were infected. Because the virus caused characteristic stripe mosaic on O. thyrsoides, we propose Ornithogalum stripe mosaic virus (OrSMV), instead of OV-2 for the proper name of the virus.
