Abstract
) are essential for ROCC. In contrast, its protein kinase and true late genes are not. We show that, unexpectedly, the viral lytic amplification is not required for chromatin compaction but is required for its margination. We propose a two-step model for ROCC: first, global chromatin compaction occurs as a cellular response to the initiation of viral DNA synthesis; then, the accumulation of newly synthesized, histone-free viral DNA leads to cellular chromatin margination. Taken together, our findings provide insights into a process contributing to the productive phase of five families of viruses.
