The first complete genome sequence of an isolate of Tobacco necrosis virus D (TNV-D; genus Necrovirus,family Tombusviridae) was that of a bean isolate from England. The complete nucleotide sequence of another
TNV-D isolate, an Hungarian isolate from tobacco plants (TNV-DH), revealed a similar genomic organization.
The single-stranded positive-sense RNA genome of TNV-D is about 3.8 kb in size and contains six open reading frames(ORFs).
