Project description:To investigate the role of iron excess in rice immune responses to Magnaporthe oryzae infection. Gene expression profiling analysis were performed using data obtained from RNA-seq of rice plants grown in differential iron supply and challenged with Magnaporthe oryzae spores.
Project description:This SuperSeries is composed of the following subset Series: GSE8517: Magnaporthe oryzae gene expression during biotrophic invasion of rice using version 2 of the Agilent Magnaporthe grisea Array (G4137B). GSE8518: Rice gene expression during biotrophic invasion by the rice blast fungus Magnaporthe oryzae using the Agilent Rice Array (G4138A). Keywords: SuperSeries Refer to individual Series
Project description:In order to understand the mechanisms of Drought induced susceptibility (DIS) we’ve conducted a dual RNAseq experiment on rice infected tissues by Magnaporthe oryzae. At 4 days post inoculation tissues have been collected on mock inoculated and M. oryzae inoculated plants. Rice were conducted under two type of water regime: DIS Drought during three days before inoculation, NoDIS no drought before inoculation. RNAseq was conducted both on rice and fungal RNA.
Project description:We report that rice inoculated with Magnaporthe oryzae at different temperatures and analysis of the whole genome expression to shed light on temperature-mediated rice disease resistance.
Project description:In this study, using a novel dual RNA-seq approach we monitored the global transcriptional changes in real time of Xanthomonas oryzae pv. oryzicola and rice during infection. Our transcriptome maps of Xoc strains infecting rice provide mechanistic insights into the bacterias adaptive responses to the host niche, with modulation of central metabolism being an important signature. The study also uncovers that infected rice responds by substantial alteration of the cell wall, stress and structural proteins.
Project description:Magnaporthe oryzae is the causative agent of the rice blast, the most relevant rice disease worldwide. To date expression analysis on rice infected with Magnaporthe oryzae have been carried out only with the strains FR13 (leaf) and Guy 11 (root). However different strains of Magnaporthe are present in the environment leading to different rice responses at molecular level. To gain more insight on the unknown molecular mechanisms activated by different Magnaporthe strains during rice defense, a global expression analysis was performed by using the GeneChip® Rice Genome Array. To identify rice genes differentially regulated upon infection by Magnaporthe isolates, inoculation with different strains were performed and samples were collected 24 hours post infection.
Project description:The Ca2+/calcineurin signaling pathway is a central conduit regulating growth, development, and virulence of fungal pathogens infecting plants and human. We have analyzed global gene expression profiles during Ca2+ treatment in the rice blast fungus, Magnaporthe oryzae. An immunosuppressive drug, FK506, and the knock-out mutant of a transcription factor, MoCRZ1, were included to analyze calcineurin- and/or CRZ1-dependent gene expression, respectively. About 1,400 genes were up or down regulated by Ca2+ treatment, while about 200 genes seemed to be up-regulated in a calcineurin/CRZ1-dependent manner.
Project description:We report that the homeobox trasncription factor called HOX7 controls hyphae-associated genes, autophagy and cell cycle related genes necessary for appressorium development in the rice blast fungus Magnaporthe oryzae. We also report that the ste transcription factor MST12 regulates gene functions involved in septin reorientation.

To identify rice genes differentially regulated upon infection by Magnaporthe isolates, inoculation with different strains were performed and samples were collected 24 hours post infection. RNA were obtained from leaf samples after inoculation of rice 2 week-old plantlets with the following strains: rice isolates Magnaporthe oryzae FR13 and CL367, non-adapted strain BR32, isolated from wheat, and Magnaporthe grisea BR29 isolated from crabgrass. Treated and control (mock) rice leaves (cv. Nipponbare) were collected 24 hours post inoculation. Three biological replicates for each interaction type and the corresponding mock were extracted and analysed independently with the GeneChip® Rice Genome Array.
