ABSTRACT
Cauliflower mosaic virus (CaMV) is a double-stranded DNA (dsDNA) pararetrovirus capable of cell-to-cell movement presumably through intercellular connections, the plasmodesmata, infected plant. This likely mediated by specific viral protein encoded gene I locus. Here we report that purified binds RNA and single-stranded (ssDNA) but not dsDNA regardless nucleotide sequence specificity. The binding highly cooperative, affinity for 10-fold higher than ssDNA. CaMV replicates reverse transcription 358 homologous to entire genome. We propose 35S may be involved in as an intermediate transported plasmodesmata RNA-gene complex.
