Abstract: | The distribution of two UK strains of barley yellow mosaic virus has been studied and both have been transmitted experimentally by Polymyxa graminis. cDNA hybridization studies support the suggestion that the strains should be considered distinct viruses. Oat mosaic and oat golden stripe (OGSV) viruses also occur in the UK. OGSV is a furovirus related to wheat soil-borne mosaic furovirus: it has particles of two lengths and a bipartite genome. |
