Begomoviruses (family Geminiviridae) cause important diseases in many crops. In addition, many wild plants are reservoirs of begomoviruses, which are a potential menace for nearby crops. A novel begomovirus was isolated from a weed of the species Synedrella nodiflora (Compositae) exhibiting yellow vein symptoms in South India. This virus had a typical monopartite Old World begomovirus genome and was accompanied by a betasatellite. Sequence comparison revealed that this virus represents a new species in the genus Begomovirus. Recombination analysis showed that the novel begomovirus originated through recombination between the begomoviruses ageratum yellow vein Sri Lanka virus and tomato leaf curl Sri Lanka virus.
