| phylogenetic relationships of closely related potyviruses infecting sweet potato determined by genomic characterization of sweet potato virus g and sweet potato virus 2. | complete nucleotide sequences of sweet potato virus g (spvg) and sweet potato virus 2 (spv2) were determined to be 10,800 and 10,731 nucleotides, respectively, excluding the 3'-poly(a) tail. their genomic organizations are typical of potyviruses, encoding a polyprotein which is likely cleaved into 10 mature proteins by three viral proteinases. conserved motifs of orthologous proteins of viruses in the genus potyvirus are found in corresponding positions of both viruses. pairwise comparisons of i ... | 2012 | 22562225 |
