Abstract
The complete nucleotide sequence of the genomic RNA of beet mild yellowing virus, isolate 2ITB, is reported. The RNA consists of 5722 nucleotides and contains six long open reading frames which conform to the arrangement characteristic of Subgroup 2 luteoviruses. The three 3′-proximal open reading frames, which encode the viral coat protein, a putative movement protein and the Readthrough Domain, are highly homologous to the corresponding genes of beet western yellows luteovirus while the three 5′-proximal open reading frames are more closely related to the corresponding genes of cucurbit aphid borne yellows luteovirus. The sequence data thus indicate that beet mild yellowing virus should be considered a distinct virus rather than a strain of beet western yellows virus.
