Abstract
When callus tissue was cultured from leaf pieces taken from a Nicotiana tabacum cv. Xanthi nc. plant systemically infected with tomato golden mosaic virus (TGMV), TGMV-specific DNA persisted for up to 6 months in culture. Analysis of TGMV-specific intracellular DNA forms indicated a decrease in double-stranded relative to single-stranded forms and an increase in sub-genomic relative to genomic single-stranded DNA species in the callus tissue compared to those in the original leaf explant. The implications of the results with regard to TGMV replication are discussed
