| sequence diversity of readthrough proteins of soybean dwarf virus isolates from the midwestern united states. | 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. phyl ... | 2009 | 19360376 |
