Summary.
The complete nucleotide sequence of Beet black scorch virus (BBSV) was determined. The BBSV genome is composed of 3641 nucleotides and has similar organization with Tobacco necrosis virus D of 61% nucleotide identity. The 5′-proximal open reading frame (ORF) encodes a putative 23 kDa protein and a 82 kDa protein by reading-through of an amber termination codon. Three small ORFs located in the center of the genome may encode for a 4.2 kDa protein and two 7 kDa proteins. The 3′-proximal ORF encodes a 24.5 kDa protein equivalent in mass to the viral coat protein. Considering biological and molecular similarities with TNV, it is concluded that BBSV is a new member of the genus Necrovirus.
