Identification of candidate non-host resistance genes for powdery mildew in barley

ABSTRACT: To identify the non-host responsive genes, a time-series based global expression profiling was performed in barley using Agilent chip. Seven-day-old barley plants of cv. Vada were inoculated with spore density of 50-80 conidia mm-2 of Bgh or Bgt, and the abaxial epidermis of inoculated primary leaves or from non-inoculated control leaves was peeled 6, 12, 24 and 74 h after inoculation. Total RNA was extracted by using the RNeasy plant mini kit with on-Column DNase digestion (Qiagen, Hilden, Germany), and hybridized to a 44K Agilent oligonucleotide custom array of barley.

Identification of candidate genes for nonhost resistance to powdery mildew in wheat

Project description:To identify the nonhost resistance genes, a time-series based global expression profiling was performed in wheat using Agilent gene expression 44K microarray array. Seven-day-old wheat plants of cv. Renan was inoculated with spore density of 50-80 conidia mm-2 of adapted (Bgt) or non-adapted (Bgh) powdery mildew pathogen, and the abaxial epidermis of inoculated primary leaves or from non-inoculated control leaves was peeled at 6, 12, 24 and 74 h after inoculation. Total RNA was extracted by using the RNeasy plant mini kit with on-Column DNase digestion (Qiagen, Hilden, Germany), and hybridized to a 44K Agilent oligonucleotide custom array of wheat.

Proteomics of non-host response in barley

Project description:Nonhost resistance, a resistance of plant species against all nonadapted pathogens, is considered the most durable and efficient immune system in plants. To increase our understanding of the response of barley (Hordeum vulgare L.) plants to infection by powdery mildew, Blumeria graminis f. sp. Tritici, we used quantitative proteomic analysis (LC-MS/MS). We compared the response of two genotypes of barley cultivar Golden Promise, wild type (WT) and plants with overexpression of phytoglobin (previously hemoglobin) class 1 (HO), which has previously been shown to significantly weaken non-host resistance. A total of 8804 proteins were identified and quantified, out of which the abundance of 1044 proteins changed significantly in at least one of the four comparisons (‘i’ stands for ‘inoculated’)- HO/WT and HOi/WTi (giving genotype differences), and WTi/WT and HOi/HO (giving treatment differences). Among these differentially abundant proteins (DAP) were proteins related to structural organization, disease/defense, metabolism, transporters, signal transduction and protein synthesis. More proteins changed in abundance in WT than in HO after inoculation and most DAP increased in abundance.

Transcription profiling by high throughput of Blumeria gramis during infection of Barley

Project description:The aim of this experiment was to investigate the transcriptomic variation within Blumeria graminis f. sp. hordei during infection of Barley. SOLiD RNA-seq data was generated for 6 samples, three from the epiphytic hyphae and three from the haustoria within the epidermis.

Transcription profiling of individual resistant and infected epidermalsingle cells of the susceptible barley line Pallas

Project description:Investigation of the interaction between barley and B. graminis. Individual resistant and infected epidermal cells of the susceptible barley line Pallas were easily distinguished by microscopy, and their contents collected in micro-capillaries. We hybridized 12 arrays with radioactively labeled material from these cell specific samples; 3 with material from resistant cells, 3 with material from infected cells, 3 with material from non-inoculated control cells, and 3 identical samples for technical replication. Pooling equal amounts of material from the 3 infected samples made these last 3 samples.

Piriformospora indica primes barley for systemic resistance against powdery mildew

Project description:Colonization of barley roots with the basidiomycete fungus Piriformospora indica enhances resistance against the leaf pathogen Blumeria graminis f.sp. hordei (Bgh). To identify genes involved in this mycorrhiza-induced systemic resistance, we used the Affymetrix Barley1 22K gene chip for leaf transcriptome analysis of P. indica-colonized and non-colonized barley plants 12, 24 and 96 hours post inoculation (hpi) with a compatible Bgh strain.

Transcription profiling by array of barley after inoculation with an adapted and a non-adapted Magnaporthe isolate or mock-inoculation to identify candidate genes for nonhost resistance against blast disease

Project description:In this experiment the transcriptome reprogramming in barley during host and nonhost interaction with Magnaporthe sp. was analyzed in a time-series approach. Seven days old barley plants of cv. Vada were mock-inoculated or inoculated with adapted Magnaporthe isolate TH6772 from rice or non-adapted isolate CD180 from Pennisetum. After 6, 12, 24 and 48 hours the abaxial epidermis was sampled. Total RNA was extracted using the RNeasy Plant Mini Kit with on-column DNase digestion (Qiagen, Hilden, Germany), and hybridized to Agilent 44k oligonucleotide arrays.

RNA-seq of enriched barley stomatal complexes versus total leaves

Project description:We intend to identify transporters and their regulators involved in barley stomatal movement as well as components of the ABA signaling pathway. We isolated epidermal peels where only stomatal guard cells and their subsidiary cells survived, while other epidermal cell were mechanically disrupted and sequenced the resulting RNAs. Thus we analyzed transcripts differentially expressed between the barley stomatal complex and total leaves. These data served as the first overview of genes expressed in the stomatal complex and for cloning of relevant transporters.

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 GeneChipM-BM-. 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 GeneChipM-BM-. Rice Genome Array hybridization. For transcript proM-oM-,M-^Aling experiments with powdery mildew, entire leaves were sampled from rice plantlets 2 weeks old (cv. Nipponbare). Treated and control (mock) rice leaves were collected 24 hours post inoculation. Three biological replicates for inoculated and control plants were extracted and analysed independently with the GeneChipM-BM-. Rice Genome Array.

Project description:In this experiment the transcriptome reprogramming in barley during host and nonhost interaction with Puccinia sp. was analyzed in a time-series approach. Ten days old barley plants of cv. Vada were mock-inoculated or inoculated with P. hordei (Ph), 1.2.1 isolate, or P. triticina (Pt), BRW96258 isolate. After 12, 24, 36 and 48 hours first leaves were sampled. Total RNA was extracted using the RNeasy Plant Mini Kit (Qiagen, Hilden, Germany), the Ambion TURBO DNA-free DNase Kit was used for DNA elimination, and RNA was hybridized to Agilent 44k oligonucleotide arrays.

Barley guard cell and subsidiary cell specific transcripts

Project description:We prepared RNA from total leaves and epidermal peels, containing living guard cells (GC) and subsidiary cells (SC) only. In the third sample we blended epidermal peels to mechanically destroy the SC, leading to a pure guard cells fraction. By RNAseq and substraction of GC from SC transcripts, we were able to reliably assign transcripts to the barley SCs and GCs.
