RNA-seq analysis of FSS1-dependent genes in Fusarium graminearum Z-3639

ABSTRACT: Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops, such as wheat, barley, and maize. FSS1 contains a Zn(II)2Cys6 fungal-type DNA-binding domain and localized exclusively to nuclei responding to sodium, suggesting that FSS1 is a TF required for sodium tolerance. By RNA-seq and genetic studies, we found a P-type ATPase pump (FgENA5) that is under control of FSS1 and is responsible for phenotypic defects of fss1 mutants. The wild-type, fss1 deletion, fss1 overexpression mutant strains were incubated in potato dextrose broth (PDB) with or without 1 M NaCl supplementation for an hour. 6 samples examined: 1 h after inoculation of Fusarium graminearum wild-type, Δfss1(Δfss1::gen), and fss1 overexpression mutant (fss1::gen-Pef1a-fss1) strains in potato dextrose broth with or without 1 M NaCl supplementation

RNA-seq Analysis of RFX1-dependent Genes in Fusarium graminearum Z-3639

Project description:Fusarium graminearum is a major pathogen of Fusarium head blight in wheat, barley, and rice, as well as ear rot and stalk rot in maize. Regulatory Factor X (RFX) transcription factors are well-conserved in animals and fungi, but their functions are diverse, ranging from DNA-damage response to ciliary gene regulation. We investigated the role of the sole RFX transcription factor, RFX1, in F. graminearum. Deletion of rfx1 resulted in multiple defects in hyphal growth, conidiation, virulence, and sexual development. Deletion mutants of rfx1 were more sensitive to various types of DNA damage than the wild-type strain. Septum formation was inhibited and micronuclei were produced in the rfx1 deletion mutants. The results of the neutral comet assay demonstrated that disruption of rfx1 function caused spontaneous DNA double-strand breaks. To understand regulatory mechanisms of rfx1 in F. graminearum, we obtained and analyzed genome-wide transcription profiles generated from the RNA-sequencing data of the wild-type and M-NM-^Trfx1 strains. RNA-sequencing-based transcriptomic analysis revealed that RFX1 suppressed the expression of many genes, including genes for the repair of DNA damage. 2 samples examined: mycelia harvested 24 h after inoculation of wild-type conidia in complete medium; mycelia harvested 32 h after inoculation of M-NM-^Trfx1 conidia in complete medium

RNA-seq analysis of Fusarium graminearum Z-3639 in heat stress

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 ÂºC) and in high temperature condition (37 ÂºC) 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 ÂºC) and in high temperature condition (37 ÂºC) for 15 min.

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

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.

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.
