Sweetpotato Viruses Cause Disease in Sweet Potato and Related Ipomoea spp.: Fulfilling Koch’s Postulates for a Divergent Group in the Genus Begomovirus

Sweet potato (Ipomoea batatas) and related Ipomoea species are frequently infected by monopartite begomoviruses (genus Begomovirus, family Geminiviridae), known as sweepoviruses. Unlike other geminiviruses, the genomes of sweepoviruses have been recalcitrant to rendering infectious clones to date. Thus, Koch’s postulates have not been fullfilled for any of the viruses in …
