Barley CI 16151 and fast-neutron-derived, immune-compromised mutants infected with the powdery mildew fungus (Blumeria graminis f. sp. hordei; isolate 5874)

Project description:Purpose: The powdery mildew fungus, Blumeria graminis, is an obligate biotrophic pathogen of cereals and has significant impact on food security (Dean et al., 2012). B. graminis f. sp. hordei (Bgh) is the causal agent of powdery mildew on barley (Hordeum vulgare L.). We sought to address the temporal regulation of membrane trafficking associated gene expression in barley-powdery mildew interactions. We created an isogenic panel of immune signaling mutants to address three main questions: (i) which Blumeria secreted proteins are differentially regulated in response to different compromised genotypes, (ii) which barley membrane trafficking genes are altered in response to pathogen attack, and (iii) how are these genes interacting across genotypes and infection stages.

Mapping barley genes to chromosome arms by transcript profiling of wheat-barley ditelosomic chromosome addition lines

Project description:We utilized the Barley1 Affymetrix GeneChip for comparative transcript analysis of Betzes barley, Chinese Spring wheat, and Chinese Spring–Betzes ditelosomic chromosome addition lines to physically map barley genes to their respective chromosome arm locations. We mapped barley genes to chromosome arms (1HS, 2HS, 2HL, 3HS, 3HL, 4HS, 4HL, 5HS, 5HL, 7HS, and 7HL) based on their transcript levels in the ditelosomic addition lines. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Hatice Bilgic.

A comparative transcriptome and chromatin modification analysis provides a resource for characterizing the regulatory roles of epigenetic modifications in hulless barley resistance response to powdery mildew

Project description:We generated ChIP-Seq data for two barley accessions with different resistance to powdery mildew. These data allowed us to explore the roles of epigenetic modifications in resistance response to powdery mildew at the first time. Our study opens the way for establishing the relationship between epigenetics and disease response in barley, and should inform future functional characterization of the regarding molecular basis. These data should also help researchers to exploit disease response-related genes for breeding application.

Transcription profiling of wild type and mutants of Sultan V barley plants

Project description:A large-scale time course expression profiling of wild type (Mla12/Rar1/Rom1) and mutants (mla12-M66, M82 (rar1-1), M100 (rar1-2) and rom1) of barley cultivar Sultan 5 was conducted to understand the molecular mechanisms of delayed powdery mildew resistance. Barley plants were inoculated with powdery mildew pathogen isolate 5874. First leaves of inoculated and non-inoculated plants were harvested at six time points after pathogen inoculation. The experiment was laid out in split-split-plot design with 180 experimental units (3 replications x 2 treatments (inoculated and non-inoculated) x 5 genotypes x 6 time points).

Transcription profiling of Arabidopsis eds1 mutant and NahG transgenics infection penetration success by the barley powdery mildew Blumeria graminis f. sp. hordei Bgh

Project description:Arabidopsis does not support the growth and asexual reproduction of the barley pathogen, Blumeria graminis f. sp. hordei Bgh). A majority of germlings fail to penetrate the epidermal cell wall and papillae. To gain additional insight into this interaction, we determined whether the salicylic acid (SA) or jasmonate (JA)/ethylene (ET) defence pathways played a role in blocking barley powdery mildew infections. Only the eds1 mutant and NahG transgenics supported a modest increase in penetration success by the barley powdery mildew. We also compared the global gene expression patterns of Arabidopsis inoculated with the non-host barley powdery mildew to those inoculated with a virulent, host powdery mildew, Erysiphe cichoracearum. Genes repressed by inoculations with non-host and host powdery mildews relative to non-inoculated control plants accounted for two-thirds of the differentially expressed genes. A majority of these genes encoded components of photosynthesis and general metabolism. Consistent with this observation, Arabidopsis growth was inhibited following inoculation with Bgh, suggesting a shift in resource allocation from growth to defence. A number of defence-associated genes were induced during both interactions. These genes likely are components of basal defence responses, which do not effectively block host powdery mildew infections. In addition, genes encoding defensins, anti-microbial peptides whose expression is under the control of the JA/ET signalling pathway, were induced exclusively by non-host pathogens. Ectopic activation of JA/ET signalling protected Arabidopsis against two biotrophic host pathogens. Taken together, these data suggest that biotrophic host pathogens must either suppress or fail to elicit the JA/ET signal transduction pathway.
