Project description:The plant pathogenic fungus Fusarium graminearum (Fgr) creates economic and health risks in cereals agriculture. Fgr causes head blight (or scab) of wheat and stalk rot of corn, reducing yield, degrading grain quality and polluting downstream food products with mycotoxins. Fungal plant pathogens must secrete proteases to access nutrition and to breakdown the structural protein component of the plant cell wall. Research into the proteolytic activity of Fgr is hindered by the complex nature of the suite of proteases secreted. We used a systems biology approach comprising genome analysis, transcriptomics and label-free quantitative proteomics to characterise the peptidases deployed by Fgr during growth. A combined analysis of published microarray transcriptome datasets revealed seven transcriptional groupings of peptidases based on in vitro growth, in planta growth, and sporulation behaviours. An orbitrap MS/MS proteomics technique defined the extracellular proteases secreted by Fusarium graminearum.

Project description:We report a complete transcriptomic study of Fusarium graminearum in response to glucose, cellulose, xylan and cell wall fragments with a whole genome microarray from febit. Fusarium graminearum was cultured at 25 °C on minimal M3 medium with glucose, birch wood xylan, carboxy methyl cellulose or hop cell wall as sole carbon source at a concentration of 10 g/L. Microarray experiments were achieved with a Geniom device (febit biomed, Germany). Each of the four tested condition was tested with two biological and two technical replicates.

Project description:Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops, such as wheat, barley, and maize. To dissect cellular responses toward heat stress in the plant pathogenic fungus F. graminearum, we compared transcriptomes of the fungal cultures incubated in normal temperature condition (25 ºC) and in high temperature condition (37 ºC) for 15 min. 6 samples examined: 24 h-old mycelia from complete medium (CM) of Fusarium graminearum wild-type Z-3639 were incubated in normal temperature condition (25 ºC) and in high temperature condition (37 ºC) for 15 min.

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

Project description:Mitogen-activated protein kinases (MAPKs) are fundamental components of the plant immune system. MAPK cascades are activated by microbial elicitors and effectors, such as microbe-associated molecular patterns (MAMPs) and damage-associated molecular patterns (DAMPs). The activation of MAPKs plays essential roles in early and late responses associated with plant defense and innate immunity. In the present experiment, we investigated the role of HvMPK3 in the resistance of barley (Hordeum vulgare) against Fusarium graminearum. The proteomes of TALEN-induced MPK3 knock-out lines of barley (HvMPK3 KO) were compared with wild types 24 h after the treatment with F. graminearum. Results explain the resistance of HvMPK KO lines to the pathogen.

Project description:Salicylic acid (SA) is one of the key signal molecules in regulating plant resistance to diverse pathogens. It is predominantly associated with resistance against biotrophic and hemibiotrophic pathogens, and triggering systemic acquired resistance (SAR) in Arabidopsis. However, whether and how SA directly affects Fusarium graminearum and how SA influences the defence efficiency of wheat against fusarium head blight (FHB) are still poorly understood. Previous experiments have shown that the growth of F. graminearum mycelia and the germination of spores were significantly inhibited, and eventually stopped by increasing amounts of SA in both liquid and solid media cultures. Co-inoculation of SA and Fg spores has led to reduced FHB symptoms in the very susceptible Triticum aestivum cultivar ‘Roblin’. To better understand the effect of SA on F. graminearum mycelial growth, we have compared the expression profiles of SA-treated and untreated F. graminearum liquid cultures after 8 and 24 h of treatment, using an F. graminearum custom-commercial microarray. The microarray analysis suggests that F. graminearum can metabolize SA through two pathways, the gentisate and catechol pathways that are present in many fungal species. Additional experiments have confirmed the capacity of F. graminearum to metabolize SA. Our results demonstrate that, although F. graminearum has the capacity to metabolize SA, SA has a significant and direct impact on F. graminearum through a reduction in efficiency of germination and growth at higher concentrations.
