Brachiaria piligera and Sorghum verticilliflorum are natural hosts of two different strains of Sugarcane mosaic virus in Australia
Australasian Plant Pathology 22 (3), 94-97
Abstract: In 1985 and 1986, during an outbreak of mosaic in sugarcane in the Isis district of Queensland, B. piligera (hairy arm grass) with mosaic symptoms was found infected with the sugarcane strain of sugarcane mosaic potyvirus (SCMV-SC). This is the first report of SCMV-SC naturally infecting a host other than sugarcane in Australia. S. verticilliflorum (wild sorghum) with mosaic symptoms in the Isis and nearby coastal districts was always infected by Johnsongrass mosaic potyvirus (JGMV), except at 1 site in Bundaberg where the sabigrass strain of SCMV (SCMV-Sabi), which does not infect sugarcane, was found. This is the first report of SCMV-Sabi occurring in wild sorghum and in a district distant from Gatton where infected sabigrass normally occurs.
