title: Bean yellow mosaic virus subgroup; search for the group specific sequences in the 3' terminal region of the genome.
abstract: In order to examine relationships among viruses of the bean yellow mosaic subgroup of the Potyvirus genus, several isolates of bean yellow mosaic virus (BYMV) and clover yellow vein virus (C1YVV) were compared by amino acid sequence of the coat protein and nucleotide sequence of the 3' terminal non-coding region. The sequence comparisons showed that BYMV and C1YVV were distinct viruses but had close affinity to each other (85-95% homology among isolates of a virus but 70-77% homology between viruses), justifying establishment of the BYMV subgroup. There was an oligonucleotide consensus sequence present in the 3' terminal non-coding region of all potyviruses examined. This consensus sequence divided the potyviruses into three groups whose significance is not clear.
