FIG. 6.

Ultrastructural morphologies of mutant viruses. Electron micrographs of Vero cells infected at an MOI of 5 with different viruses and processed for electron microscopy at 16 hpi are shown. Enlarged sections of each micrograph are included as insets in each panel. ΔUL20 (constructed previously) is the mutant virus that has the entire UL20 gene deleted (25). UL20ctgctg is the mutant virus containing two ATG-to-CTG codon initiation mutations six bases apart. Nucleus (n), cytoplasm (c), and extracellular space (e) are marked.
