Transcription profiling of wild type and loss-of-function mutants of Mla1 and Mla6 powdery mildew resistant allele barley plants

Project description:A parallel expression profiling of wild-type and loss-of-function mutants of Mla6 and Mla1 powdery mildew resistance alleles was conducted using Barley1 GeneChip. Barley plants were inoculated with powdery mildew isolate 5874 and first leaves were harvested at 6 time points after pathogen inoculation. This experiment was conducted in split-split-plot experimental design with 3 replications.

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.

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).

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.

Arabidopsis pen3 mutant and wild type Col-O comparison under host inoculation, nonhost inoculation and no inoculation.

Project description:Arabidopsis is a host to the fungal powdery mildew pathogen, Erysiphe cichoracearum, and a nonhost to Blumeria graminis f.sp. hordei, the powdery mildew pathogenic on barley. A screen for mutants that allowed increased entry by this inappropriate or nonhost pathogen on Arabidopsis led to the identification of PEN3. While pen3 mutants permitted both increased penetration and increased hyphal growth by B. g. hordei, they were unexpectedly resistant to E. cichoracearum. This resistance was correlated with the appearance of chlorotic patches and was salicylic acid-dependent. Consistent with this observation, microarray analysis revealed that the salicylic acid defense pathway was hyper-induced in pen3 relative to wild type following inoculation with either E. cichoracearum or B. g. hordei. The pen3 phenotypes result from a loss of function of AtPDR8, a ubiquitously and highly expressed ATP binding cassette transporter. PEN3 protein tagged with green fluorescent protein localized to the plasma membrane in uninfected cells. In infected leaves, the protein concentrated to high levels at infection sites and surrounded fungal penetration pegs. We hypothesize that PEN3 may be involved in exporting toxic substrates to sites of infection and that accumulation of these substrates intracellularly in the pen3 mutant may secondarily activate the salicylic acid pathway.
