Abstract excerpt
Four regions covering 1247 nucleotides of the RNA genome of 20 isolates of a Vitivirus, Grapevine virus B (GVB), from three countries were analyzed. All the regions in these isolates varied in sequence as compared to the published GVB sequence. Of these, the intergenic region varied the most, with 73.2% nucleotide sequence homology, while ORF4 encoding coat protein varied the least when compared both at...
