摘要： Recently, the importance of the Geminiviruses infecting cereal crops has been appreciated, and they are now being studied in detail. Barley and wheat strains of Wheat dwarf virus are recorded in most European countries. Information on complete sequences of isolates from the United Kingdom, Spain, and Austria are reported here for the first time. Analysis revealed that their sequences are very stable. Recombination between strains was recorded only for the barley strain. We identified several defective forms of the barley strain from barley and wheat, which do not influence symptom expression. Sequences of barley isolates infecting wheat were obtained that did not differ from the isolates from barley. Based on specific features of the SIR of the barley strains, it is suggested that they are assigned to one of the two proposed new clusters, A1 or A2.
