| Abstract: | The complete sequence of the two RNAs of a furovirus isolate from durum wheat in Italy was determined. Sequence comparisons
and phylogenetic analysis were done to compare the Italian virus withSoilborne wheat mosaic virus (SBWMV) from the USA and with furovirus sequences recently published asEuropean wheat mosaic virus (EWMV), from wheat in France, andSoilborne rye mosaic virus (SBRMV), from rye and wheat in Germany. Over the entire genome, the Italian isolate RNA1 and RNA2 had respectively 97.5%
and 98.6% nucleotide identity with EWMV, 95.5% and 85.8% with SBRMV-G and 70.6% and 64.5% with SBWMV. The Italian isolate
was therefore clearly distinct from SBWMV The European isolates all appear to belong to the same virus and the nameSoilborne cereal mosaic virus may resolve earlier ambiguities. |
