Project description:Transcription profiling of the DSF regulon in Xanthomonas oryzae pv. oryzae (Xoo) using wild type and the rpfF mutant. Cell-cell signaling mediated by the quorum sensing molecule known as Diffusible Signaling factor (DSF) is required for virulence of Xanthomonas group of plant pathogens. DSF in different Xanthomonas and the closely related plant pathogen Xylella fastidiosa regulates diverse traits in a strain specific manner. The transcriptional profiling performed in this study is to elucidate the traits regulated by DSF from the Indian isolate of Xanthomonas oryzae pv. oryzae, which exhibits traits very different from other Xanthomonas group of plant pathogen. In this study, transcription analysis was done between a wild type Xanthomonas oryzae pv. oryzae strain and an isogenic strain that has a mutation in the DSF biosynthetic gene rpfF.
Project description:The molecular mechanisms underlying infection of rice host system with compatible M. oryzae isolates at 12, 24, 48 and 72 hours post innoculation (hpi) are investigated in the study. In addition, the identification of highly commonly upregulated genes by both isolates of M. oryzae may be useful candidates for M.oryzae inducible promoter characterization We used microarrays to detail the global programme of gene expression underlying M. oryzae infection during compatible host-pathogen interaction
Project description:Transcriptional profiling of Oryza sativa japonica Nipponbare roots after 14 days post infection with Xanthomonas oryzae pv. oryzae strain PXO99 , the goal is to understand the transcriptomic response of rice roots to colonization by bacterial pathogen
