TL;DR: The finding of ToLCBV in G. niveum plants with typical symptoms, signifying persistent natural infection, is a new record and the detected monopartite virus differed significantly from previously reported bipartite begomovirus causing leaf curl disease in tomato plants from nearby regions.
Abstract: Taken together, our finding of ToLCBV in G. niveum plants with typical symptoms, signifying persistent natural infection, is a new record. Although the possibility of a new viral genome created by DNA recombination remains to be explored, the detected monopartite virus differed significantly from previously reported bipartite begomovirus causing leaf curl disease in tomato plants from nearby regions (Reddy et al., 2005). Interestingly, the G. niveum identified ToLCBV DNA-A was associated with the ToLCBV betasatellite. This data contrasted with the detection of tobacco curly shoot virus (TbCSV) DNA-A (KP143684) being associated with tomato leaf curl virus (ToLCV) DNA-s (KP143683) in symptomatic tomato plants, grown in the same experimental field, during 2010 (Datta et al., unpublished). In conclusion, we report G. niveum as a natural host of ToLBCV and an interesting molecular epidemiology of begomovirus in this part of India.
