Abstract
Three viruses were found from gloriosa (Gloriosa rothschildiana), cultivated at Chiba in 1979-1980, showing leaf symptoms of fleck, stripe mosaic or mottling. A rhabdovirus, ca. 69×316nm, having helical nucleocapsid with a pitch of 4.5nm, was consistently detected in dip and thin-sectioned preparations from the fleck plants. Nucleus of infected cells was characterized by the development of nuclear viroplasms. It suggested that the virus is a rhabdovirus of nuclear multiplication type. As such rhabdovirus has been so far undescribed in Liliaceae, the virus was designated as gloriosa fleck virus (GlFV). A potyvirus, ca. 13×760nm, accompanying cytoplasmic inclusions was detected from stripe mosaic or mottling plants. The virus was transmitted only to gloriosa by sap inoculation, and identified to be gloriosa stripe mosaic virus (GSMV) reported in Germany. Cucumber mosaic virus (CMV) was also detected mainly from the plants showing mottling symptoms.
