Abstract

The amino acid sequence diversity of readthrough proteins (RTPs) of 24 dwarfing isolates of Soybean dwarf virus (SbDV) from Wisconsin and Illinois was analyzed. The RTP, a minor component of viral capsids, has a significant role in specificity of aphid transmission of luteovirids. Among the isolates, nucleotide sequence identities ranged from 95 to 100%. The predicted amino acid sequences differed at 56 amino acid positions in the 54 kDa RTD compared to only five positions in the 22 kDa CP. Phylogenetic analysis of both amino acid and nucleotide sequences showed three distinct clusters of SbDV isolates.
