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.

Summary. -A one-step immunocapture real-time RT-PCR (IC-real-time RT-PCR) was developed for efficient detection of barley stripe mosaic virus (BSMV) in barley seedlings. The novel detection system was designed using a primer set targeting the conserved region in the triple gene block 2 (TGB2) to expand its capacity to detect all BSMV strains. This assay was evaluated for its efficiency in detecting BSMV in barley seedlings. Using the immunocapture sample preparation, real-time RT-PCR was able to detect BSMV in samples, which were indicated as negative by ELISA. The sensitivity of detection in the real-time RT-PCR was as low as 50 fg/µl of total viral RNA under optimal reaction conditions. This level of sensitivity indicated that the one-step IC-realtime RT-PCR developed in the present study could be used for routine plant and seed health assays.
