Nucleotide sequence analysis of peanut stunt virus Rp strain suggests the role of homologous recombination in cucumovirus evolution.
The complete nucleotide (nt) sequence of peanut stunt virus Robinia strain (PSV-Rp) was determined and compared to other PSV strains and to representatives of the genus Cucumovirus. Nt sequence comparison showed 74.1-84.6% identity with the known PSV strains. Phylogenetic analysis revealed the different origin of the two genes encoded by RNA3. While the 3a gene clustered with PSV-W, the coat protein gene clustered with PSV-Mi. Recombination breakpoint analysis revealed two recombination points on RNA3. Based on these results, the establishment of a fourth PSV subgroup is proposed. This work revealed that homologous recombination occurred during the evolution of PSV.
