Comparison of the gene expression patterns (the {\overline{\mathit{R}}}_{\mathit{r}}values) in three mutant viruses. The{\overline{R}}_r values of the us1-, ep0- and vhs-null mutants were visualized in a heatmap presentation. The expression profile of the us1-KO virus is similar to that of the vhs-KO, i.e. complementary to that of the ep0-KO virus.
