Figure 5From: The ICP22 protein selectively modifies the transcription of different kinetic classes of pseudorabies virus genesComparison of the gene expression patterns (the R ¯ r values) in three mutant viruses. The 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.Back to article page
