Regulation of fliTX transcription in Xanthomonas oryzae pv. oryzae. a β-galactosidase activity assay. Activities of the fliS promoter in Xoo strains were detected. The experiments were repeated three times, independently. b qRT-PCR analysis of genes in fliS operon and fliA in Xoo strains. The data represents the relative expression level of genes in PXO99A, ∆fliA, ∆fleQ and ∆rpoN2. The error bar represents standard deviations from three biological repeats
