Confluent dishes of BSC40 cells were infected with the Dts38 helper virus and co-transfected with wild-type genomic DNA (“WT Genome”) and the indicated PCR product. After a 4 day incubation at 37°C in the presence of IBT, dishes were stained with crystal violet. In this and some other experiments, plaques appearing in the control dish (“WT genome”) probably represent IBT resistant viruses, most likely arising from spontaneous IBT resistance alleles present in the wild type virus genomic DNA used in co-transfection experiments.
