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

ABSTRACT: 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.

Fusarium head blight (FHB) disease adversely affects grain quality and final yield in small-grain cereals including barley. In the present study, 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 (BBCH 73) 10days after pathogen inoculation (10 dai).

affy_brachy_2011_11-Transcriptomics analysis of DON and Fusarium graminearum response in Brachypodium distachyon

Project description:affy_brachy_2011_11 - affy_brachy_2011_11 - Fusarium graminearum is the causal agent of Fusarium head blight (FHB) of small-grain cereals, including wheat. Besides direct grain losses, this disease is of major concern because of the production by the pathogen of mycotoxins which are hazardous to animals, thus making the grain unfit for food or feed. Major mycotoxins produced by the fungus are trichothecens, including deoxynivalenol (DON). In our laboratory, we use Brachypodium distachyon as a model plant for cereals because of its amenability (short life cycle, numerous genomic and genetic resources, ...). We have recently shown that F. graminearum does induce head blight symptoms on this species and that DON is produced on infected spikes. We have also evidenced that a F. graminearum strain unable to produce DON exhibits reduced virulence on B. distachyon spikes, as previously shown on wheat. The aim of this project is to analyse and compare the plant response to DON producing and non-producing strains of F. graminearum. This analysis will allow to decipher the mechanisms of detoxification set up by the plant and also more specific responses due to the impact of the mycotoxin on plant metabolism and physiology. -Three conditions on B. distachyon spikes: 1-Mock inoculation (Tween 20 0,01%) 2-Inoculation by a F. graminearum wild-type strain 3-Inoculation by a F. graminearum mutant strain, unable to produce DON Spikes were point inoculated with 3ul of either Tween 20 0.01%, wild-type strain or mutant strain (300 spores) and incubated for 96 hours. Six inoculated spikes were collected and pooled for each condition and biological replicate. Three independent biological replicates were conducted. 9 arrays - Brachypodium; normal vs disease comparison,time course

Transcriptome-based comparison of the infection response in maize silks between Fusarium graminearum and Ustilago maydis

Project description:In this study, RNA-seq based comparative transcriptome analysis was used to study the response between Fusarium graminearum and Ustilago maydis to different growth conditions. RNA-seq libraries were generated from fungal filaments growing in culture (complete medium) and from infected maize silk. This data set contains the data for the Fusarium graminearum and Ustilago maydis medium growth condition.

RNA-seq-based analysis of the pathogen-induced defense transcriptome in Arabidopsis

Project description:Pathogen infection triggers transcriptional reprogramming in host plants, however we still know little about the dynamics of the pathogen-induced defense transcriptome. The goal of this study was to investigate the dynamic reprogramming of the defense transcriptome in response to Fusarium oxysporum infection in Arabidopsis using RNA-seq technology and to provide a comprehensive analysis of genes underlying the innate immune response against the fungal pathogen. Our results suggest that the Arabidopsis transcriptome is reprogrammed to co-ordinately express multiple positive and negative regulators following pathogen infection to modulate defense gene expression and disease resistance. Our study identified a number of novel genes responsive to pathogen infection and provided a rich source of pathogen responsive genes for further functional characterization. Four samples (M1DPI, M6DPI, F1DPI and F6DPI; M=mock treated; F=Fusarium oxysporum infected; DPI=day post inoculation) were sequenced to identify pathogen responsive genes in each time point. Each sample was sequenced once, i.e. without biological replicate.

Deoxynivalenol affects the gene expression of A549 lung epithelial cells

Project description:Deoxynivalenol (DON) is an important Fusarium toxin of concern for food safety. The inhalation of powder contaminated with deoxynivalenol is possible and may cause lung toxicity. In this study, we investigated the gene expression profile of A549 cells treated with 0.2 microg/mL deoxynivalenol by microarray analysis. In total, 16 genes and 5 noncoding RNAs were significantly affected by deoxynivalenol treatment.

Genome-wide gene expression analysis of Fusarium graminearum isolate PH-1 in spores and mycelium

Project description:Using RNA-Seq data from the mycelium of Fusarium graminearum, we found weakly expressed regions on all of the four chromosomes that exactly matched with non-conserved regions. Comparison of gene expression between two different developmental stages (spores and mycelium) showed that the expression of genes in conserved regions is stable, while gene expression in non-conserved regions is much more influenced by developmental stage. Examination of gene expression in two developmental stages (spores and mycelium). Three biological replicates were performed for each stage.

Gene expression in non-perfused liver samples from endotoxemic Sus scrofa in context of deoxynivalenol contaminated diets

Project description:It has been proposed that chronic exposure to deoxynivalenol modulates hepatic gene expression and that sensivity to xenobiotics like deoxynivalenol is modulated by inflammation. We used microarrays to evaluate whether chronic deoxynivalenol exposure influences the hepatic gene expression of Sus scrofa in vivo and whether interaction between chronic deoxynivalenol exposure and systemic inflammation occur.

Structural dynamics in the evolution of SARS-CoV-2 spike glycoprotein: HDX-MS analysis of the spike of alpha, beta, delta and omicron variants - in apo state and in complex with the ACE2 receptor

Project description:The spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mediates binding to the ACE2 receptor and subsequent membrane fusion. It exists in a range of conformations, including a closed state unable to bind the ACE2 receptor, and an open state that does so but displays more exposed antigenic surface. Spikes of variants of concern (VOCs) acquired amino acid changes linked to different opening probabilities, increased SARS-CoV-2 virulence and immune evasion. Here, using hydrogen-deuterium exchange mass spectrometry (HDX-MS), we analyzed the spike of the original Wuhan isolate, G614 mutant, spike of alpha, beta, delta and omicron VOCs and the isolated ancestral receptor binding domain (RBD) - in apo state and in complex with the ACE2 receptor. We identified changes in spike dynamics that we associated with the transition from closed to open conformation, to ACE2 binding, and to specific mutations in VOCs. We show that the RBD-associated subdomain plays a role in spike opening, whereas the NTD acts as a hotspot of conformational divergence of VOC spikes driving immune evasion. Alpha, beta and delta spikes assume predominantly open conformations and a strong ACE2 binding increases the dynamics of their core helices, priming spikes for fusion. Conversely, substitutions in omicron spike lead to predominantly binding-incompetent closed conformations, presumably enabling it to escape antibodies. At the same time, its core helices show characteristics of being pre-primed for fusion even in the absence of ACE2. These data inform on SARS-CoV-2 evolution and omicron variant emergence.
