The complete nucleotide sequence of Beet black scorch virus (BBSV), a new member of the genus Necrovirus

Y Cao et al. Arch Virol. 2002 Dec.

Abstract

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.
