The complete sequence of a UK strain of black raspberry necrosis virus.

The complete nucleotide sequence of a UK strain of the sadwavirus Black raspberry necrosis virus (BRNV) was obtained by amplification and sequencing of virus RNA from infected plants grown in a raspberry plantation in Aylth, Scotland. The RNA1 was 7,572 nucleotides (nt) in size and RNA2 was 6,350 nt in size, each excluding the 3' poly-A tail. The RNA1- and RNA2-encoded polyproteins are predicted to be processed into (RNA1) a protease cofactor, an RNA helicase, the VpG, a 3C-like protease, an RNA-dependent RNA polymerase and an AlkB protein, and (RNA2) a movement protein and two capsid proteins.
