Transcription profiling of RaxR-regulon members of Xanthomonas oryzae pv. oryzae PXO99A

ABSTRACT: Xanthomonas oryzae pv. oryzae strain PXO99A, so called Xoo, is disable to infect in rice cultivar carrying Xa21 gene. Disrupted mutant of raxR gene, response regulator of two-component regulatory system (TCS), in Xoo was previously shown to partially retrieve back the bacterial capability to establish in Xa21 rice. RaxR was shown to mediate the expression of other rax gene operon members and also its expression is changed dependent on cell population density. In this study, we investigated the regulatory mechanisms mediated by RaxR using whole-genome transcriptional profiling analysis in comparison of (i) PXO99R (PXO99 strain lacking RaxR) vs. PXO99, (ii) PXO99Rox (PXO99 strain overexpressing RaxR) vs. PXO99, and (iii) PXO99Rox vs. PXO99R. As a result of array analysis, we revealed that Ra
