Bioinformatics analysis of fliTX in Xanthomonas oryzae pv. oryzae. a Schematic diagram of the region including fliTX in the genome of PXO99^A. Open arrows indicate length, location and orientation of the ORFs. The short lines below the arrows indicate the location and length of RT-PCR products. The lower element shows the RT-PCR analysis of RNA isolated from PXO99^A. RT-dependent amplification of DNA fragments suggested that the fliS, fliTX and flgZ were transcribed in one operon. The lowest element shows the fliTX was in-frame deleted in ∆fliTX. b Sequence alignment of FliTX was performed using DNAMAN software. The amino acid sequences of FliT were obtained from the National Center for Biotechnology Information (NCBI) website. E. coli: Escherichia coli strain MG1655; S. typhimurium Salmonella typhimurium LT2 strain; P. fluorescens: Pseudomonas fluorescens strain F113; X. oryzae: Xanthomonas oryzae pv. oryzae strain PXO99^A. The amino acid residues highlighted with black means the homology level is 100%
