Alterations in kernel proteome after infection with Fusarium culmorum in two triticale cultivars with contrasting resistance to Fusarium head blight

Project description:Triticale was used as a model to recognize new components of molecular mechanism of resistance to Fusarium head blight (FHB) in cereals. Fusarium-damaged kernels of two lines distinct in levels of resistance to FHB were applied into a proteome profiling using two-dimensional gel electrophoresis (2-DE) to create protein maps and mass spectrometry to identify the proteins differentially accumulated between the analyzed lines. The 2-DE analysis indicated a total of 23 spots with clear differences in a protein content between the more resistant and more susceptible triticale lines after infection with F. culmorum. A majority of the proteins were involved in a cell carbohydrate metabolism, stressing the importance of this protein group in a plant response to Fusarium infection. The increased accumulation levels of different isoforms of plant beta-amylase were observed for a more susceptible triticale line after inoculation. The more resistant line was characterized by a higher abundance of alpha-amylase inhibitor CM2 subunit.

Genome-wide expression profiling of Fusarium graminearum in response to azole fungicide treatment

Project description:In this study, a newly developed 8x15K Fusarium graminearum Agilent microarray was applied to analyze transcriptional responses to azole fungicide treatment. Comparative statistical analysis of expression profiles from treated versus untreated fungal liquid cultures uncovered 1058 genes that were significantly differentially expressed. Among the 596 genes with significantly increased transcript levels, analyses using GeneOntology and FunCat annotations detected the ergosterol-biosynthesis pathway genes as the most significantly responding category, providing statistical confirmation of the mode-of-action of azole fungicides. Transcriptional profiling of 54 genes, which encode ABC transporters in F. graminearum, suggested that several of these might be involved in reducing intracellular fungicide concentration. In addition, several genes encoding transcription factors with similarity to yeast genes known to co-ordinate fungicide responses exhibited significant differential expression. Hybridization was performed with cRNA samples either derived from three independent untreated or three independent azole-treated liquid cultures (12 h at 5 mg/l tebuconazole).

The effect of Fusarium culmorum infection and deoxynivalenol (DON) application on proteome response in barley cultivars Chevron and Pedant

Project description:The effect of an artificial infection with Fusarium culmorum and an application of deoxynivalenol (DON) on barley spikes of cultivars Chevron and Pedant during flowering was investigated at grain mid-dough stage 10 days after pathogen inoculation (10 dai). Proteomic analysis using a two-dimensional differential gel electrophoresis (2D-DIGE) technique coupled with LC-MS/MS was used to investigate the quantitative or qualitative differences between the experimental variants.

Differential transcription network analysis for Fusarium head blight disease of barley in combination with drought stress

Project description:For improvement of stress and disease resistance of barley, this global transcriptomic study focuses on how drought conditions affect Fusarium head blight (FHB) severity in spring barley. In general, drought-stress prior to Fusarium culmorum infection reduced FHB-susceptibility. This study gives evidence, that FHB-severity and strength of drought responses is variety-dependent under complex stress situations.

Metabolomic Aspects of Conservative and Resistance-related Elements of Response to Fusarium culmorum in the Grass Family

Project description:BACKGROUND: Fusarium head blight (FHB) is a serious fungal disease of crop plants due to substantial yield reduction and production of mycotoxins in the infected grains. The breeding progress in increasing resistance with maintaining a high yield is not possible without a thorough examination of the molecular basis of plant immunity responses.METHODS: LC-MS based metabolomics approaches powered by three-way ANOVA and differentially accumulated metabolites (DAMs) selection, correlation network and functional enrichment were conducted on grains of resistant and susceptible to FHB genotypes of barley and wheat as well as model grass Brachypodium distachyon (Bd) still poorly known at metabolomic level.RESULTS: We selected common and genotype-specific DAMs in response to F. culmorum inoculation. Immunological reaction at metabolomic level was strongly diversified between resistant and susceptible genotypes. DAMs common for all tested species from porphyrins, flavonoids and phenylpropanoids metabolic pathways were highly correlated and reflects conservativeness in FHB response in Poaceae family. Resistant related DAMs belonged to different structural classes including tryptophan derived metabolites, pirimidines, amino acids proline and serine as well as phenylpropanoids and flavonoids. Physiological response to F. culmorum of Bd was close to barley and wheat genotypes however, metabolomic changes were strongly diversified. CONCLUSIONS: Combined targeted and untargeted metabolomics provides comprehensive knowledge about significant elements of plant immunity with potential of being molecular biomarkers of enhance resistance to FHB in grass family. Thorough examination of Bd21 metabolome in juxtaposition with barley and wheat diversified genotypes facilitate their setting as model grass for plant-microbe interaction.
