Agrobacterium tumefaciens, a bacterial plant pathogen, when transformed with plasmid constructs containing greater than unit length DNA of tomato leaf curl geminivirus accumulates viral replicative form DNAs indistinguishable from those produced in infected plants. The accumulation of the viral DNA...
