Transcriptome analysis of rice ABA deficient mutant Osaba1-1 and wild-type before and 72h after Xanthomonas oryzae pv. oryzae (Xoo) infection

ABSTRACT: 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.

Transcriptome analysis of rice ABA deficient mutant Osaba1-1 and wild-type before and 72h after Xanthomonas oryzae pv. oryzae (Xoo) infection

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. Osaba1-1 and wild-type rice plants about 6.5 leaf stage were used in this experiment. For Xoo inoculation, tips (about 3cm) of the fifth and sixth fully expanded leaves were cut off, and then immersed into Xoo (PXO99 strain) inoculum (suspended in sterile distilled water containing 10mM MgCl2, OD≈0.5) immediately for about fifteen seconds. Inoculated rice leaves were collected (approximately 2 cm leaf fragment from the inoculation site) at 0h and 72h post inoculation. Three independent replicate samples were collected at each time point for microarray.

Transcriptome Profiling of Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola on two different medias

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.

Xanthomonas oryzae pv. oryzae (Indian Isolate): Wild type vs. rpfF mutant

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.

Transcriptome profile of rice genotypes ZH11 and Oseds1 by inoculation with Xanthomonas oryzae pv. oryzae

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).

RNA-seq analysis of in planta condition-dependent genes in Xanthomonas oryzae pv. oryzae KACC10331

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.

Time-resolved genome-wide pathogenic gene expression analysis of the plant pathogen Xanthomonas oryzae pv. oryzae (Xoo) via RNA-Seq

Project description:Host-pathogen interactions, in particular during the early stages of infection, are important for the fate of both the invading pathogen and host. In pathogens, these interactions activate diverse pathogenic signals to cause disease in the host and evade the inevitably activated immune responses of the infected host. In this study, we used in vitro assay system and RNA-seq to analyze the time-resolved genome-wide gene expressions of Xanthomonas oryzae pv. oryzae (Xoo) evoked by the interactions with rice leaf extracts. RNA-seq analysis was carried out with samples of 7 different time points within 1 h. The RNA-seq data were verified by qRT-PCR. The in vitro system successfully initiated the pathogenic signals in Xoo cell culture. Many pathogenicity-related genes were expressed within 15 min. The hrpG gene was transcribed at maximum level within 10 min, and hrpX gene expression reached maximum level in 15 min. Chemotaxis and flagellar biosynthesis-related genes and cyclic-di-GMP synthesizing genes having GGDEF motif, were down-regulated until 10 min and after then up-regulated. Genes related to iron uptake and two component systems of phoB-phoR, phoP-phoQ, and pmrA-pmrB were up-regulated before 5 min. Data of multiple time points enabled non-linear regression fit of the time-resolved expression data, with which we newly developed the continuous time-resolved heat map to help the comparison of gene expression profiles. Essentiality of the transcriptionally up-regulated genes was also analyzed by the pathogenicity assay using the Xoo knockout strains, which showed not necessarily all the up-regulated genes were required for pathogenicity. the time-dependent, 0, 5, 10, 15, 30, 45, and 60 min, transcriptome analysis of genome-wide Xanthomonas oryzae pv. oryzae genes from the pathogenic interactions with RLX via RNA-Seq
