LC-MSMS of Hordeum vulgare epidermis containing haustoria from Blumeria graminis f.sp. hordei

Project description:Blumeria graminis f.sp. hordei is an obligate biotrohic fungal pathogen causing powdery mildew in barley. As for other biotrophic fungi, haustorial structures are at the centre of the biotrophic interaction and molecular exchanges, delivering fungal effectors or virulence factors, and taking nutrient from the host. Haustoria are originiated by the fungus, following successful penetration of the initial penetration peg through the plant cell call. Haustorial structures mainly of fungal origin, but they are surrounding by a plant component, the extrauhaustorial membrane and matrix (EHM and EHMx) forming the extrahuastorial complex (EHMc). The plant protein make-up of the plant extrahaustorial components remained unexplored, and this is a first study trying to describe plant proteome associated with haustoria using samples enriched for these structures. Therefore, proteomes of haustoria enriched samples from the epidermis of barley leaves infected with Blumeria graminins f.sp. hordei, the causing agent of barley powdery mildew, were compared to infected epidermis and un-infected epidermis to identify haustoria associated plant proteins. Haustoria were enriched from infected epidermis by digesting epidermal cell walls with cell wall degrading enzymes prior to enrichment for haustorial structures. Proteins identified in these samples were compared to infected and uninfected epidermis samples using a non-targeted label free semi-quantitation method.

Small RNA sequencing of Barley CI 16151 and fast-neutron-derived, immune-compromised mutants infected with the powdery mildew fungus (Blumeria graminis f. sp. hordei (Bgh); 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. Molecular Plant Pathology 13 (4): 414-430. DOI: 10.1111/j.1364-3703.2011.00783.x). Blumeria graminis f. sp. hordei (Bgh) is the causal agent of powdery mildew on barley (Hordeum vulgare L.). We sought to identify small RNAs (sRNAs) from both barley and Bgh that regulate gene expression both within species and cross-kingdom.

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.

Genetic regulation of barley gene expression in response to the powdery mildew fungus, Blumeria graminis f. sp. hordei (Bgh)

Project description:Expression analysis was performed on total RNA from the Q21861 and SM89010 barley lines, and 75 derived doubled haploid progeny, with CI 16137 included as an internal Mla1 allele control. Samples were blocked by time-point and completely randomized within each block. For each sample, seven day old seedlings were inoculated with Blumeria graminis f. sp. hordei (Bgh) isolate 5874 (AVRa1, AVRa6, AVRa12), and first leaves were collected at 16 and 32 hours after inoculation (HAI). ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Roger Wise.

Rice gene global expression during nonhost interaction with Blumeria graminis f. sp. hordei (Bgh)

Project description:Powdery mildew is a very common plant disease and only few plants are immune. Host interactions have been identified and characterized for the pathosystems barley-B. graminis f. sp. tritici (Bgt) and wheat-B. graminis f. sp. hordei (Bgh), whereas no data are reported about powdery mildew and nonhost plants, such as rice. On the other hand rice nonhost resistance is widely unexploited and only few expression data are available. To characterize rice response during nonhost interaction with Bgh, a global expression analysis was performed by using the GeneChip® Rice Genome Array. To describe rice gene expression profiles during nonhost interaction, 2 week-old rice plantlets were inoculated with Bgh. Treated (inoculated) and control (mock) samples were collected 24 hours post-inoculation for GeneChip® Rice Genome Array hybridization.
