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:OsEDS1 is a key regulator of SA-mediated immunity in plants. The OsEDS1 knockout mutant (Oseds1) was characterized and shown to have increased susceptibility to Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), suggesting the positive role of OsEDS1 in regulating rice disease resistance. To identify differentially regulated downstream of Oseds1, we performed transcriptome deep sequencing (RNA-seq) of wild type (ZH11) and Oseds1 inoculated with Xanthomonas oryzae pv. Oryzae (PXO99A).

Project description:Xanthomonas oryzae pv. oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc) are important bacterial pathogens of the worldwide staple and grass model, rice. Xoo invades rice vascular tissue to cause bacterial leaf blight, a serious disease of rice throughout the world. Xoc colonizes the parenchyma tissue to cause bacterial leaf steak, a disease of emerging importance. We have designed oligonucleotide probes (50-70-mers) represented 2,858 Xoo genes and 1,816 Xoc genes annotated by The Institute for Genomic Research (TIGR). To validate the Xo arrays, self-hybridization samples and tests of the non-specific hybridization using randomly spotted oligonucleotides corresponding to the hygromycin phosphotransferase gene (hph), and blank spot and of the correlation coefficient between biological replicates as well as between duplicate spots revealed that the data generated from our oligo array were highly reliable and consistent. To demonstrate application of Xo array, we performed expression profiling experiments on arrays hybridized with RNA of Xoo and Xoc grown in the two different nutrient-condition media. Several sets of genes involved in bacterial movement, chemotaxis, and hrp genes differentially express in response to different treatment. Due to comprehensive views of microarray study, extended biological events of plant-bacteria interaction was described. This publicly available microarray for Xanthomonas oryzae (Xo) is an enabling resource for a large and international community of scientists to better understand not only Xo biology but also many other Xanthomonas species that cause significant losses on crops.

Project description:Xanthomonas oryzae pv. oryzae strain PXO99A, so called Xoo, is disable to infect in rice cultivar carrying Xa21 gene. A set of experiments indicated that Ax21 is quorum sensing factor in PXO99 strain. To observe fine-tuned details how Ax21 controls expression of PXO99 in response to change of cell population density, transcriptional profiling analysis was perform by using published two channel oligo Xo microarray platform (Seo et al.,2008 BMC microbiology).

Project description:ABA deficient mutant Osaba1-1 exhibits great resistance to Xanthomonas oryzae pv. oryzae (Xoo) infection. To investigate gene expression profile changes at whole genome level between Osaba1-1 and wild-type (Nipponbare) rice during Xoo infection, we employed microarray expression profiling as a discovery platform.

Project description:Xanthomonas oryzae pv. oryzae (Xoo) causes the bacterial leaf blight of rice, which leads to as much as 50% yield losses. To understand the landscape of virulence mechanisms, we constructed in planta transcriptional profiling of Xoo KACC10331 using RNA-seq. Three in planta transcriptome of Xoo KACC10331 derived from infected rice leafs were compared to three in vitro data from rich media. To obtain differentially expressed genes, we used the DEGseq package with MA-plot-based method in the R statistical environment and identified 2,094 transcripts that were significantly altered.

Project description: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 RaxR is not only required for AvrXa21 activitiy, it also plays roles in regulatory functions, for example, pathogenicity, motility, and stress tolerance. Then, we generated knock out mutants of RaxR regulon members to validate regulatory functions of RaxR and to extend other biological impacts of RaxR beyond the Xoo AvrXa21 activity. The combined interpretation from array analysis and mutant functional validation presents the complexity of regulatory pathways between AvrXa21 activity and other biological activities in Xoo.
