Abstract

We determined the complete or partial nucleotide sequences of eight Sweet potato feathery mottle virus (SPFMV) isolates and compared them with 12 other partial SPFMV sequences. The genome organization of the isolate Bungo (strain group C) was very different from those of isolates in the russet crack, ordinary (O), and east Africa groups. 10-O appeared to be a recombinant of isolates S and O, with a recombination site within the P1 gene. This study will help to provide a better understanding of the taxonomy and biology of SPFMV and how these features relate to virulence.
