Sweet potato is one of the most important vegetables in the world, being one of the main sources of nutrients in some countries. Despite being considered a resistant plant, it hosts several pathogens, mainly viruses. Previously, most viruses reported in the crop had a genome composed of RNA, however, in recent years DNA viruses have been highlighted. Among them are the species belonging to the genus Badnavirus (family Caulimoviridae). Therefore, the aim of the present study was to identify the presence of viral species belonging to the genus Badnavirus in sweet potato leaf samples collected in the main producing regions of the city of Pelotas-RS. Through the PCR amplification it was possible to detect 48 positive samples among the 303 samples tested, using degenerate and specific primers for species of the genus. A chosen sample used for analysis with other pairs of specific primers, in order to achieve genome sequences. However, it was not possible to obtain the complete genome sequence, only partial. The generated fragments showed an identity between 72 to 87% when compared to the complete genome of the isolates SPV-A (FJ560943.2) and SPV-B (FJ560944.1), thus demonstrating the great variability that exists between them. Further, studies will carried out in order to obtain the complete sequence of the genome, to better understand the action of the virus on the plant.
