Evaluation plots for differentially expressed immunogenes. (A) Radial plots of t values, p values and logFC values for the differential expression test. The blue, red and green lines indicate t values, logFC values and p values, respectively. (B) Two-way hierarchical clustering of differentially expressed immunogenes. Rows represent genes and columns represent samples. Ctr-1, Ctr-2 and Ctr-3 were the control samples, and HPS-1, HPS-2 and HPS-3 were the Haemophilus parasuis-infected samples. (C) Comparisons of expression values of differentially expressed immunogenes between samples. The normalized MAS5 expression values were used here.
