Host transcriptional reprogramming across diverse strains of the rice bacterial leaf streak pathogen Xanthomonas oryzae pv.oryzicola

ABSTRACT: We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with 10 geographically diverse strains of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak. Results provide insight into the molecular basis of bacterial leaf streak, particularly the role of transcription activator-like effectors in the disease. Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation with 10 strains of Xanthomonas oryzae pv.oryzicola with three biological replicates for each compared to three replicates of mock inoculated O sativa as the control

TAL effectors and activation of predicted host targets distinguish Asian from African strains of the rice pathogen Xanthomonas oryzae pv. oryzicola while strict conservation suggests universal importance of five TAL effectors.

Xanthomonas oryzae pv. oryzicola (Xoc) causes the increasingly important disease bacterial leaf streak of rice (BLS) in part by type III delivery of repeat-rich transcription activator-like (TAL) effectors to upregulate host susceptibility genes. By pathogen whole genome, single molecule, real-time sequencing and host RNA sequencing, we compared TAL effector content and rice transcriptional responses across 10 geographically diverse Xoc strains. TAL effector content is surprisingly conserved ove ...[more]

Host transcriptional reprogramming in response to the rice bacterial blight pathogen Xanthomonas oryzae pv.oryzae constitutively expressing the X. oryzae pv. oryzicola TAL2a effector from the high copy vector pKEB31

Project description:We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with Xanthomonas oryzae pv. oryzae strain PXO99A heterologously expressing the Tal2a effector, the designer TAL effector dT280 which targets a sequence overlapping the predicted Tal2a binding sequence in UCH, or the Tal11b effector. Results provide insight into the genes differentially regulated in a Tal2a- and dT280-specific manner. Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation. Each leaf was considered a separate biological replicate.

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.

Expression data from infected (Xanthomonas oryzae pv. Oryzae (P10)) leaf in japonica rice (cv. Y73)

Project description:Previously, we successfully introduce the bacterial blight resistance trait from Oryza meyeriana into O. sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a progeny named Y73 was generated with recurrent parent O. sativa L. ssp. japonica cv. Dalixiang, and it shows high resistance to broad-spectrum of bacterial blight pathogens Xanthomonas oryzae pv. Oryzae (Xoo). However, the resistance mechanism of Y73 is remain undiscovered. To provide insights into the high resistance phenotype of these plants, we examined the transcriptome response in leaves of Y73 to the bacterial blight infection in this study. Xoo inoculated and mock inoculated rice plants were grown in growth room and the global analysis of gene expression events in rice leaves at 24 hours post inoculation (hpi) were analyzed using Affymetrix Rice GeneChip microarrays. We used microarrays to detail the global programme of gene expression underlying Xoo infection in rice Y73. To find out pathways and genes involved in its high and board-spectrum resistance, microanalysis were carried out on Y73 after Xoo infection at 24 hours post inoculation (hpi). Three independant replicates were perfomed for each treatments.

Xanthomonas oryzae pv. oryzicola (Indian Isolate) wild type and complented strains vs rpfF mutant grown under iron starved condition

Project description:Transcriptional profiling of DSF regulon under iron starvation in Xanthomonas oryzae pv. oryzicola (Xoc; BXOR1) using wild type, rpfF mutant and rpfF mutant with complementing plasmid pSC9. Cell-cell signalling mediated by quorum sensing molecule known as Diffusible signalling factor (DSF) is required for the virulence of Xanthomonas group of plant pathogens. The transcriptional profiling in this study is to elucidate the role of DSF in iron acquisition under the iron limitting environment which would lead to successful colonization and pathogenesis inside host.
