Sequence analysis of a soil-borne wheat mosaic virus isolate from Italy shows that it is the same virus as European wheat mosaic virus and Soil-borne rye mosaic virus.
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 with Soil-borne wheat mosaic virus (SBWMV) from the USA and with furovirus sequences recently published as European wheat mosaic virus (EWMV), from wheat in France, and Soil-borne 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 name Soil-borne cereal mosaic virus may resolve earlier ambiguities.
