Gene expression in rice roots in response to inoculation with rice blast fungus

Project description:Rice roots grown in hydroponic culture were inoculated with rice blast fungus and gene expression profiles were analyzed by microarray Roots of two isogenic lines of rice cv Nipponbare (blast-resistance gene: Pia or pia) were inoculated with rice blast fungus, P91-15B, carrying avirulence gene, AvrPia. Total RNA was isolated from crown roots, labeled with cy3, and probed with agilent rice oligoarray (4x44).

Transcriptome study of rice early response to rice blast fungus

Project description:Rice blast disease is a major threat to rice production worldwide, but the mechanisms underlying rice resistance to the causal agent Magnaporthe oryzae remain elusive. In this whole-genome transcriptome study of rice early defense response to M. oryzae, we applied Affymetrix Rice Genome Genechip to compare the compatible and incompatible rice-M. oryzae interactions in 24 hours post-inoculation. Leaf samples were harvested from three biological replicates of fungal- and mock-inoculated seedlings at 24 hours post-inoculation, from which RNA were extracted and analyzed with Genechip Rice Genome Array.

Positive roles for Osa-miR7695 in regulating defense responses against the rice blast fungus

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional regulators of gene expression in eukaryotes. In rice, miR7695 targets an alternatively spliced transcript of natural resistance-associated macrophage protein 6 (OsNramp6) encoding an iron transporter whose expression is regulated by infection with the rice blast fungus Magnaporthe oryzae. Rice plants grown under high iron supply showed blast resistance, which supports that iron is a factor in controlling blast resistance by still unknown mechanisms. Here, iron accumulated near M. oryzae appressoria, the sites of pathogen entry, and in cells surrounding infected regions of the rice leaf. Activation-tagged MIR7695 rice plants (MIR7695-Ac) exhibited enhanced resistance to M. oryzae infection. RNA-seq analysis revealed that blast resistance in MIR7695-Ac plants was associated with strong induction of defense-related genes, including pathogenesis-related and diterpenoid biosynthetic genes. Levels of phytoalexins during pathogen infection were higher in MIR7695-Ac than wild-type plants. Early phytoalexin biosynthetic genes, OsCPS2 and OsCSP4, were highly upregulated in rice plants grown under high iron supply. Our data indicate that miR7695 positively regulates rice immunity while establishing links between defense and iron signaling in rice. MiR7695-mediated regulation of OsNramp6 has great potential for the development of strategies to control rice blast disease.

The phosphorylation landscape of infection-related development by the rice blast fungus

Project description:Many of the world’s most devastating crop diseases are caused by fungal pathogens which elaborate specialized infection structures to invade plant tissue. Here we present a quantitative mass spectrometry-based phosphoproteomic analysis of infection-related development by the rice blast fungus Magnaporthe oryzae, which threatens global food security. We mapped 8,005 phosphosites on 2,062 fungal proteins, revealing major re-wiring of phosphorylation-based signaling cascades during fungal infection. Comparingme phosphosite conservation across 41 fungal species reveals phosphorylation signatures specifically associated with biotrophic and hemibiotrophic fungal infection. We then used parallel reaction monitoring to identify phosphoproteins directly regulated by the Pmk1 MAP kinase that controls plant infection by M. oryzae. We define 33 substrates of Pmk1 and show that Pmk1-dependent phosphorylation of a newly identified regulator, Vts1, is required for rice blast disease. Defining the phosphorylation landscape of infection therefore identifies potential therapeutic interventions for control of plant diseases.
