Project description:Purpose: To explore the mechanism of Frenolicin B could control the Fusarium Head Blight on Wheat. Methods: Fusarium graminearum were inoculated into PDB broth and cultivated 36 hours. After that, Frenolicin B was added in the broth of Fusarium graminearum, and the same volumes of methanol were served as the control. Then incubated together 6 hours.
Project description:To investigate the inhibition metabolism of EB1 in Fusarium graminearum, F.graminearum wild type grown in YPD broth. Then harvested F.graminearum hyphae reacted with EB1 during 1, 2, 4h.
Project description: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
Project description:Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes) and developing seeds. This study compare the gene expression profile in wheat spikelets (spk 2) inoculated with either water (mock treatment) or a pathogenic strain of Fusarium graminearum (WT); spikelets 2 were inoculated 24 hrs after a neighbour spikelet (spk 0) was treated with either water or F. graminerum mutant strain Tri6Δ or NoxABΔ. Spikelets 2 were sampled 8 and 24 hrs after the second treatment.
Project description:In this study, an in vitro antifungal growth experiment showed that the inhibitory rate of the MCF broth on pathogenic fungi (Fusarium oxysporum f. sp. lycopersici, Botrytis cinerea, Trichothecium roseum, and Colletotrichum gloeosporioides) was less than that of B. amyloliquefaciens culture fermentation (BCF). Moreover, the content and gene expression of lipopeptide antibiotics was also lower than that in the BCF group. However, the pot experiments based on irrigation with appropriately diluted fermentation broth showed that the biocontrol effect of MCF on tomato Fusarium wilt was significantly higher than that of TCF (T. longibrachiatum culture fermentation) and BCF, and was approximately 15.79% higher than that of the BTF group which made by mixing equivalent amounts of BCF and TCF. In MCF broth, two microorganisms antagonized and coexisted, and the growth of T. longibrachiatum was inhibited. Using transcriptomic methods, we speculated that MCF can up-regulate the expression of genes related to carbon and nitrogen metabolism, oxidation–reduction activity, sporulation, environmental information response and chemotaxis, and biosynthesis of secondary metabolites of B. amyloliquefaciens, which might enhance the nutrient substances metabolism and competitiveness, survival ability, colonisation, and adaptability to the environment to increase its biocontrol potential.

Project description:We performed ChIP-seq of histone modifications and RNA-seq in WT and kmt6 mutant Fusarium graminearum grown in high and low nitrogen conditions.
Project description:Fungal effectors play important roles in inciting disease development on host plants. We identified an effector (Secreted in Xylem4, SIX4) in an Arabidopsis infecting isolate (Fo5176) of the root-infecting fungal pathogen Fusarium oxysporum and demonstrated this effector is required for full virulence. To explore the role of Fo5176_SIX4 we use whole transcriptome profiling of root tissues from plants overexpressing this effector (35sSIX4) versus wild-type (Col-0) plants after F. oxysporum infection. We grew both WT and 35sSIX4 plants for four weeks in soil. After four weeks the plants were infected with Fusarium oxyporum isolate Fo5176, trays covered with a plastic dome and incubated at 28C. There were four independent replicates of each treatment and each replicate contained root tissue from 20 plants. Each replicate (8 in total) was harvested 4 days post inoculation and the resulting RNA was used for hybridization to an Affymetrix ATH1 chip.
Project description:We performed genome-wide transcriptome analyses of the Fusarium fujikuroi wild type (WT) in comparison to deletion mutants of the histone methyltransferase genes SET2 and ASH1 The results show that the two methyltransferases control large sets of genes involved in primary and secondary metabolism due to the modifications of the chromatin structure (methylation of histone 3 lysine 36)
