Abstract

Complete genomic sequences of nine isolates of sweet potato symptomless virus 1 (SPSMV-1), a virus of the genus Mastrevirus in the family Geminiviridae, were determined from sweet potato accessions from different countries and found to be 2,559-2,602 nucleotides in length. These isolates shared 97-100% genome sequence identity and had an unusual nonanucleotide sequence (TAAGATTCC) in a large intergenic region as well as an additional open reading frame, C3, which is conserved in dicot-infecting mastreviruses.
