Tomato leaf curl Bangalore virus (ToLCBV): infectivity and enhanced pathogenicity with diverse betasatellites.
Genomic components of a begomovirus isolated from tomato plants showing leaf curl and stunting symptoms in farmer's fields at Hessarghatta village near Bangalore, India, were cloned by rolling-circle amplification. The virus was identified as a variant of strain C of the species Tomato leaf curl Bangalore virus and designated as Tomato leaf curl Bangalore virus-C[India:Hessarghatta:2008], ToLCBV-C[IN:Hess:08]. The betasatellite isolated from these samples belongs to the betasatellite species Tomato leaf curl Bangalore betasatellite. ToLCBV-C[IN:Hess:08] induced severe symptoms in Nicotiana benthamiana and Solanum lycopersicum plants when co-inoculated with the cognate betasatellite, Tomato leaf curl Bangalore betasatellite-[India:Hessarghatta:2008], ToLCBB-[IN:Hess:08] and with two other non-cognate betasatellites, Cotton leaf curl Multan betasatellite-[India:SriGanganagar:2002] and Luffa leaf distortion betasatellite-[India:Luffa:2004].
