Abstract

The complete genome sequences of two monopartite begomovirus isolates (genus Begomovirus, family Geminiviridae) that occurred either alone or in mixed infection in sweet potato (Ipomoea batatas) plants collected in Waterpoort, South Africa, are presented. One of the isolates corresponds to sweet potato mosaic-associated virus (SPMaV; SPMaV-[ZA:WP:2011]), with which it shared 98.5 % nucleotide identity, whereas the second isolate corresponds to a new variant of sweet potato leaf curl Sao Paulo virus (SPLCSPV; SPLCSPV-[ZA:WP:2011]), with which it shared 91.4 % nucleotide identity. The phylogenetic and recombination relationships of these isolates to other monopartite Ipomoea-infecting begomoviruses were also investigated. SPLCSPV-[ZA:WP:2011] was found to be a natural recombinant of swepoviruses consisting of two distinct parental genomic sequences from SPLCSPV and sweet potato leaf curl Georgia virus (SPLCGV).
