Interpretive Summary: Infection of soybean plants by viruses can reduce the quantity and quality of seeds harvested. While Soybean mosaic virus was long considered the most widespread and damaging virus in soybean in North America, other viruses, including a growing list of newly discovered viruses, have been shown in the last decade to be more prevalent and damaging to soybean. In this study, an additional new virus of soybean was isolated from an Ohio soybean field, molecularly characterized and provisionally named Soybean Putnam pararetrovirus. While all previously described viruses of soybean in North America have had RNA genomes, Soybean Putnam pararetrovirus has a DNA genome. The distribution of the virus in soybean growing regions, its mode(s) of transmission and impacts on soybean yields remain to be determined. The results of this study will be of interest to scientists who are studying soybean diseases and their management.

Technical Abstract: We report the complete genome sequence of Soybean Putnam pararetrovirus (SPPRV), a new pararetrovirus isolated from a soybean field in Putnam County, Ohio, USA. Comparison of SPPRV with other plant-infecting pararetroviruses places it in the genus Caulimovirus of the family Caulimoviridae.
