Nucleotide sequence analyses of genomic RNAs of Peanut stunt virus Mi, the type strain representative of a novel PSV subgroup from China.

The complete nucleotide sequence of Peanut stunt virus strain Mi (PSV-Mi) from China was determined and compared to other viruses of the genus Cucumovirus. The tripartite genome of PSV-Mi encoded five open reading frames (ORFs) typical of cucumoviruses. Distance analyses of four ORFs indicated that PSV-Mi differed sufficiently in nucleotide sequence from other PSV strains of subgroups I and II to warrant establishment of a third subgroup of PSV.
