Fig. 1From: The QseB/QseC two-component system contributes to virulence of Actinobacillus pleuropneumoniae by downregulating apf gene cluster transcriptionEffect of qseBC deletion on the transcription of apf gene cluster. RT-qPCR analysis of transcription levels of genes in the apf gene cluster in WT S4074, ΔqseBC and CΔqseBC strains. mRNA levels were normalized to 16S rRNA gene for each strain. Data are shown as mean ± SD (N = 3). *P < 0.05Back to article page
