First report of Panicum mosaic virus in buffalo grass (Stenotaphrum secundatum) from Australia

摘要

Panicum mosaic virus (PMV) was identified from Stenotaphrum secundatum (buffalo grass or St Augustine grass) showing leaf mosaic symptoms, from New South Wales. The isometric virions were decorated by antibodies to PMV by immunosorbent electron microscopy. The coat protein gene was 85% and 90% identical, at the nucleotide and amino acid levels, respectively, to the published sequence of PMV. This represents the first record for PMV for Australia, and the first outside North America.
