RNA-seq Analysis of FlbD-, AbaA-, and WetA-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. 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

RNA-seq analysis of transcriptomes at 1 day after sexual induction in Fusarium graminearum strains

Project description:Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops, such as wheat, barley, and maize. To dissect molecular mechanisms for initial stage of perithecia development, we compared transcriptomes of fungal cultures harvested from F. graminearum wild-type strain Z-3639, abaA, and fpo1 at 1 day after sexual induction. 9 samples examined: Fungal cultures harvested from Fusarium graminearum wild-type strain Z-3639, abaA, and fpo1 at 1 day after sexual induction.

RNA-seq analysis of FHS1-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. Fhs1 contains a Zn(II)2Cys6 fungal-type DNA-binding domain and localized to nuclei , suggesting that Fhs1 is a transcription factor required for hydroxiurea. 6 samples examined: 24 h after inoculation of Fusarium graminearum wild-type Z-3639 and fhs1 (Îfhs1::GEN) strains in complete media

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 transcriptomes at 5 day after sexual induction in Fusarium graminearum strains

Project description:Fusarium graminearum (teleomorph Gibberella zeae) is a prominent pathogen that infects major cereal crops, such as wheat, barley, and maize. To dissect molecular mechanisms of small non-coding RNA-mediated gene regulation during ascospore production, we compared transcriptomes of fungal cultures harvested from F. graminearum wild-type strain Z-3639 and RNAi component mutants at 5 days after sexual induction.

RNA-seq analysis of FSS1-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. 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
