The complete genome sequences of two monopartite begomovirus isolates (genus Begomovirus, family Geminiviridae) present in a single sweet potato (Ipomoea batatas) plant collected in So Paulo, Brazil, are presented. Based on the current taxonomic criteria for the genus Begomovirus, one of the isolates was shown to represent a novel species, tentatively named Sweet potato leaf curl Sao Paulo virus (SPLCSPV). The other isolate represented a new strain of sweet potato leaf curl virus, named sweet potato leaf curl virus-Sao Paulo (SPLCV-SP). The full genome sequence of the SPLCSPV isolate shared the highest nucleotide identity (87.6%) with isolates of sweet potato leaf curl Spain virus (SPLCESV). Phylogenetic and recombination analyses were used to investigate the relationships of these isolates to other monopartite Ipomoea-infecting begomoviruses.
