Abstract: In Europe, beet western yellows luteovirus (BWYV) and beet mild yellowing luteovirus (BMYV) cause economically important diseases in oilseed rape (Brassica napus L.) and sugar beet (Beta vulgaris L.), respectively. The acronym BMYV is invariably described in the literature as a synonym of BWYV. However, our studies have shown that all luteovirus isolates from oilseed rape differed from those from sugar beet in host range, transmissibility by aphid vectors, and serological reactivity with monoclonal antibodies. BWYV and BMYV have different sequence data, and this has been exploited in using RT-PCR to differentiate between them. We have concluded that European luteovirus isolates pathogenic to the genus Brassica represent a separate virus, which, because it is non-pathogenic to the genus Beta, should no longer be designated 'beet' western yellows virus. We propose that the Brassica-infecting luteovirus should be renamed turnip yellows virus (TuYV), the name by which it was originally describved. 'BMYV' should be retained for luteovirus isolates pathogenic to sugar beet.
