First report of soil-borne wheat mosaic virus (SBWMV)-infecting triticale in Poland.
The virus in naturally infected, stunted triticale plants was identified as soil-borne wheat mosaic virus (SBWMV). The infected plants were collected in the Southern Wielkopolska region (Western Poland). Molecular analysis including RT-PCR, and sequencing of the complete coding sequence of coat protein gene, was performed. The sequence of the Polish isolate of SBWMV (SBWMV-Pol1) shared 100, 99 and 98% identities with the corresponding regions of De1 (AF519799), OKL-1 (X81639) and US-Nebraska (L07938) isolates of SBWMV, respectively. Phylogenetic analyses showed that the Polish isolate, SBWMV-Pol1, clustered together with other SBWMV isolates. This is the first report of the occurrence of SBWMV in Poland and the second of its presence in Europe.
