Project description:To test whether non-coding RNAs play roles in regulating response to powdery mildew infection and heat stress in wheat, by using Solexa high-throughput sequencing and computational analysis and experimental approach we cloned the small RNAs and identified 125 putative long npcRNAs from wheat leaves infected by preponderant physiological strain Erysiphe graminis f. sp. tritici (Egt) or by heat stress treatment. Among long non-coding RNAs, some were precursors of small RNAs such as microRNAs and siRNAs, two long npcRNAs were identified as signal recognition particle (SRP) 7S RNA variants, and three were characterized as U3 snoRNAs. Wheat long npcRNAs showed tissue dependent expression patterns and were responsive to powdery mildew infection and heat stress.

Wheat long npcRNAs showed tissue dependent expression patterns and were responsive to powdery mildew infection and heat stress. Examination non-coding RNAs of 2 near isogenic lines 8866 (Susceptible) and Pm30 (Resistant) in response to powdery milew and two genotypes CK (insensitive) and TAM107 (insensitive) to heat. CK and TAM107 represent the same material in different treatments (no heat stress or 1hour after heat stress).

Project description:We used two wheat genotypes, the susceptible wheat cultivar ‘8866 ’(S) and its near isogenic line with single powdery mildew resistance gene ‘pm30’ (R), to investigate gene expression changes in response to powdery mildew infection by using Wheat Genome Array

Project description:We used two wheat genotypes, the susceptible wheat cultivar ‘8866 ’(S) and its near isogenic line with single powdery mildew resistance gene ‘pm30’ (R), to investigate gene expression changes in response to powdery mildew infection by using Wheat Genome Array wheat young leveas of near isogenic lines before or 12 hours after powdery mildew infection were selected for RNA extraction and hybridization on Affymetrix microarrays.The leaf samples were harvested from three independent biological replicates, and the leaves without inoculation were regarded as control.

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.

Project description:Powdery mildew, caused by the fungus Blumeria graminis (DC) Speer, is one of the most important foliar diseases of cereals worldwide. It is an obligate biotrophic parasite, colonising leaf epidermal cells to obtain nutrients from the plant cells without killing them. Syringolin A (sylA), a circular peptide secreted by the phytopathogenic bacterium Pseudomonas syringae pv. syringae, triggers a hypersensitive cell death reaction (HR) at infection sites when sprayed onto powdery mildew infected wheat which essentially eradicates the fungus. The rational was to identify genes whose expression was specifically regulated during HR, i.e. genes that might be involved in the switch of compatibility to incompatibility.<br>Powdery mildew-infected or uninfected plants were treated with syringolin two days after infection and plant material for RNA extraction was collected at 0.5, 1, 2, 4, 8, 12 hours after treatment (hat), resulting in an early (2 and 4 hat) and late pool (8 and 12 hat). Plant material that was uninfected prior to syringolin treatment was collected 8 and 12 hat (late pool of uninfected plant material), and 1 hat, respectively.

Project description:We performed RNA-sequencing of Golovinomyces orontii-infected Arabidopsis leaves of wild type, the double or triple mutants of AtMLKLs to examine the role of AtMLKLs in response to the powdery mildew fungus.

Project description:The edr1 mutant of Arabidopsis thaliana displays enhanced resistance to the powdery mildew Golovinomyces cichoracearum, resulting in cell death and an absence of visible disease symptoms. To better characterize and understand the defense response of edr1, a time course of early signaling responses was performed after inoculation with powdery mildew and compared to the responses of wild-type Col-0. These time points represent early stages in the infection process, before any signs of susceptibility or resistance are visible.

Project description:To identify genes involved in susceptibility, genechip hybridization experiments were performed in order to examine genes differentially expressed upon inoculation of resistant and susceptible wheat cultivars with powdery mildew. Some genes were identified which were just expressed in the susceptible host both after mock-inoculation and pathogen infection. Also, a total of 2693 transcripts were differentially expressed (fold change≥2) in Yumai 13 in response to powdery mildew as compared to itself, comprising 1464 and 1229 up- and down-regulated genes respectively.
