Transcriptional responses of Fusarium graminearum to plant cell wall substrates

ABSTRACT: 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.

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.

Role of fungal cellulases upon plant infection

Project description:Role of fungal cellulases upon Fusarium oxysporum infection. We obtained Fusarium oxysporum mutants, which cannot degrade cellulose capacity to observe their virulence. Cellulose degradation is not mandatory for Fusarium oxysporum to reach the plant vasculature system.

Proteomic analysis reveals metabolic versatility of Amycolatopsis sp. BX17: a strain native from milpa agroecosystem soil

Project description:Amycolatopsis sp. BX17 is an actinobacterium isolated from milpa soils that antagonizes the phytopathogenic fungus Fusarium graminearum. Metabolites secreted by the actinobacterium cultured in medium without glucose inhibited 100% the mycelial growth of F. graminearum RH1, while in medium supplemented with 20 g/L of glucose inhibition was 65%. With the aim of studying how the metabolism of strain BX17 is modulated by glucose, as the main carbon source, media with 0 and 20 g/L glucose were selected to analyze the intracellular proteins by quantitative label-free proteomic analysis.

Transcriptional profiling of biomass degradation-related genes during Herbivorax saccincola A7 growth on different carbon sources

Project description:Herbivorax saccincola A7 is an alkali-thermophilic lignocellulolytic bacterium that was known to possess a strong xylan degradation ability. They can utilize a wide range of carbon sources, however the response and regulation mechanisms to different carbon sources, in terms of genes expression, are still not identified. In this study, H. saccincola A7 was cultured with cellobiose, cellulose, xylan, cellulose-xylan mixture, and empty fruit bunch (EFB) as the sole carbon source. We carried out a comparative expression analysis, focusing on biomass degradation-related genes. The cellulosomal scaffolding proteins and cellulosomal enzymes of H. saccincola A7 were drastically induced when a cellulose-containing substrate was used as a carbon source. On the other hand, xylan induced only some non-cellulosomal enzymes that might be necessary for xylan degradation. The identification of the carbohydrate-sensing mechanism in H. saccincola A7 appeared a similar system as previously described in Clostridium thermocellum. The lignocellulose degradation ability of H. saccincola A7 may be controlled enzyme expression by cellulose-containing substrate, not by xylan. Thus, recognition in the existence of cellulosic substrates is effective in enhancing a high xylan degradation ability in H. saccincola A7.

RNA-seq Analysis of FlbD-, AbaA-, and WetA-dependent Genes in Fusarium graminearum Z-3639

Project description:Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops, such as wheat, barley, and maize. Conidiogenesis had been intensively studied in Aspergillus nidulans and regulatory pathway genes have been known to regulate conidiogenesis in stage specific manner. We reported the functional analyses of flbD, abaA, and wetA orthologs in F. graminearum. To understand genome-wide transcriptional profiling of conidiation, we employed RNA-seq of the wild-type Fusarium graminearum Z-3639 and each gene deletion mutants with three time courses (0 h, 6 h and 12 h after induction of conidiogenesis). AbaA experiment: 6 samples examined: 0 h, 6 h and 12 h after induction of conidiogenesis of Fusarium graminearum Z-3639 wild type and ΔabaA(ΔabaA::gen) mutant strains WetA experiment: 3 samples examined: 0 h, 6 h and 12 h after induction of conidiogenesis of Fusarium graminearum ΔwetA(ΔwetA::gen) mutant strains flbD experiment: 3 samples examined: 0 h, 6 h and 12 h after induction of conidiogenesis of Fusarium graminearum ΔflbD(ΔflbD::gen) mutant strains

Genome-wide expression profiling reveals transcriptional reprogramming in Fusarium graminearum by FgV1-DK21 virus infection

Project description:Using a 3′-tiling microarray covering the whole F. graminearum genes, we carried out genome-wide expression analyses of F. graminearum infected with FgV-DK21 (Mycovirus) at two different time stages (36 h and 120 h). Our study is the first report which elucidated the global alternation of the prominent cellular pathways in fungal host by FgV1-DK21 virus infection. A total of 12 chips were used for microarray. At 36 h and 120 h, total RNAs were extracted from virus free Fusarium and virus infected Fusarium with three biological replicates.

Molecular pathogenetic study of Fusarium head blight in highly resistant, resistant and susceptible common wheat (Triticum aestivum L.)

Project description:Fusarium graminearum (F.g) is responsible for Fusarium head blight (FHB), which is a destructive disease of wheat that accumulates mycotoxin such as deoxynivalenol (DON) and makes its quality unsuitable for end use. Several FHB resistant varieties development is going on world-wide. However the complete understanding of wheat defence response, pathogen (Fusarium graminearum) disease development mechanism and the gene crosstalk between organisms is still unclear. In our study focused to analyse pathogen (F. graminearum) molecular action in different Fusarium head blight resistance cultivars during the disease development. To understand the Fusarium graminearum pathogen molecular reaction, microarray gene expression analysis was carried out by using Fusarium graminearum (8 x 15k) Agilent arrays at two time points (3 & 7 days after infection) on three wheat genotypes (Japanese landrace cv. Nobeokabouzu-komugi - highly resistant, Chinese cv. Sumai 3 - resistant and Australian cv. Gamenya - susceptible), which spikes infected by Fusarium graminearum ‘H-3’strain. During the disease development the pathogen biomass as well as the expression of Trichothecene biosynthesis involved genes (Tri genes) in three wheat cultivars was determined. In our material no relation between fungus biomass and the disease symptoms were observed, however, it showed relation with fungus virulence factors expression (Tri genes). For the first time, we report the nature of Fusarium graminearum gene expression in the FHB-highly resistant cv. Nobeokabouzu-komugi during the disease development stage and the possible underlying molecular response.
