| الوصف: | Severe symptoms of cotton leaf curl disease (CLCuD) are caused by the association of a single-stranded circular DNA satellite (betasatellite) with a helper begomovirus. In this study, we analyzed 40 leaf samples (primarily cotton with CLCuD symptoms and other plants growing close by) from four sites between New Delhi and the Pakistan/India border, using rolling-circle amplification (RCA) and PCR. In total, the complete sequences of 12 different helper viruses, eight alphasatellites, and one betasatellite from five different plant species were obtained. A recombinant helper virus molecule found in okra and a novel alphasatellite-related DNA from croton are also described. This is the first report of the presence of both DNA components (helper virus and betasatellite) associated with resistance-breaking CLCuD in India, and it highlights the need for further work to combat its damage and spread. |
