Diverse begomovirus-betasatellite complexes cause tomato leaf curl disease in the western India.

ABSTRACT: In the Indian sub-continent, tomato leaf curl disease (ToLCD) of tomato caused by begomoviruses has emerged as a major limiting factor for tomato cultivation. Despite the spread of this disease in the western India, a systematic study on the characterization of virus complexes with ToLCD is lacking. Here, we report the identification of a complex of begomoviruses including 19 DNA-A and 4 DNA-B as well as 15 betasatellites with ToLCD in the western part of the country. Additionally, a novel betasatellite and an alphasatellite were also identified. The recombination breakpoints were detected in the cloned begomoviruses and betasatellites. The cloned infectious DNA constructs cause disease on the tomato (a moderately virus-resistant cultivar) plants, thus fulfilling Koch's postulates for thes
