Gene expression during early infection of the susceptible spring wheat cultivar Roblin with Fusarium graminearum, the major causal agent of fusarium head blight in wheat

ABSTRACT: Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes). This study compare the gene expression profile in wheat spikelets from the very susceptible spring wheat cultivar Roblin inoculated with water (H2O) or Fg.

Gene expression during priming-induced resistance to fusarium head blight in wheat as revealed by two distinct mutants of Fusarium graminearum

Project description:Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes) and developing seeds. This study compare the gene expression profile in wheat spikelets (spk 2) inoculated with either water (mock treatment) or a pathogenic strain of Fusarium graminearum (WT); spikelets 2 were inoculated 24 hrs after a neighbour spikelet (spk 0) was treated with either water or F. graminerum mutant strain Tri6Δ or NoxABΔ. Spikelets 2 were sampled 8 and 24 hrs after the second treatment.

RNA profiling of Fusarium head blight-resistant wheat addition lines containing the Thinopyrum elongatum chromosome 7E

Project description:Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affecting the flowering heads (or spikes). A FHB resistance locus has been identified on the chromosome 7E of the wild wheat relative Thinopyrum elongatum (Th.e.). That chromosome (7E) or a long arm fragment of it (7EL) have been transferred as additions in the wheat background 'Chinese Spring' (CS). The two addition lines are resistant to FHB while 'Chinese Spring' is moderately susceptible to it. The mechanism of resistance is not known. The analysis of this work is published in the Canadian Journal of Plant Pathology (Wang et al, 2010). We used the wheat microarray to determine the global expression profil in inoculated spikelets of the addition and parental lines, after water or Fg treatment, with samplings at 2 and 4 days after inoculation (DAI).

Project description:Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes) and developing seeds. This study compares the gene expression profile of heads from the susceptible cultivar Roblin after inoculation with either water (W) or the disarmed Fg strain tri6Δ (T6). Tri6 is a global transcription regulator affecting the trichothecene biosynthesis pathway.

Differential transcriptome analysis of two wheat genotypes in their response to Fusarium head blight

Project description:Fusarium Head Blight (FHB) is a disease of wheat and other cereal crops, where, among other species, Fusarium graminearum infects the wheat inflorescence. Microarrays were used to observe differential gene expression in FHB-challenged spikes of the two European winter wheat genotypes Dream (moderately resistant) and Lynx (susceptible). Plants were either inoculated with the Fusarium graminearum strain IFA 65 (IFA Tulln) (500 macroconidia/floret) or were as control plants mock treated with desalted water. The inocula were injected into four spikelets at early anthesis and spikelets were later on collected at 32 and 72 h after inoculation. Four plants were sampled per genotype/treatment/sampling date. Total RNA was extracted from collected spikelets, and microarray analysis was performed using the Affymetrix Wheat GeneChip.
