Figure 4From: Whole-genome analysis of pseudorabies virus gene expression by real-time quantitative RT-PCR assayClustering of genes on the basis of the effects of PAA on gene expression. Horizontal bars show the PRV genes ranked on the basis of Ri-PAA values in an increasing sequence. Early and late gene clusters were separated by a set of genes labeled as E/L using arbitrarily given threshold values.Back to article page
