Numbers of differentially expressed genes. A Summary of differentially expressed transcripts responding to Salmonella inoculation (2 dpi/d0, 7 dpi/d0, 7 dpi/2 dpi), or expression showing time effect. B Comparison of differentially expressed gene counts in LS/PS animals as reported by Huang et al. . These genes were identified using the linear mixed model, and the false discovery rate (FDR) was controlled at less than 0.05, with the fold change between time points required to be higher than 1.5 or less than 0.67.
