摘要：
The complete nucleotide (nt) and deduced amino acid (aa) sequences of the C (common) and CRS (chlorotic ringspot) Argentine strains of SuCMoV have been determined. The SuCMoV-C RNA genome consists of 9,965 nt, whereas indels within the P1 coding region of SuCMoV-CRS make its genomic length 15 nt shorter. Nucleotide and aa sequence identities between the polyproteins of the C and CRS strains of SuCMoV were 92.3 and 95.6%, respectively. Pairwise comparisons between the polyproteins of the C and CRS strains of SuCMoV and the viruses of the Potato virus Y (PVY) subgroup revealed identities of 66.5-66.9% at the nt level and 69.7-69.8% at the aa level. These results and phylogenetic analyses show that although SuCMoV strains cluster together with the potyviruses belonging to the PVY subgroup, SuCMoV should be considered a member of a distinct species in the genus Potyvirus.
