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.

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
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.

Project description:Using a 3'-tiling microarray covering the whole F. graminearum genes, we carried out genome-wide expression analyses of both a wild type and a FgVelB deletion strainn of F. graminearum at a sexual stage (3 days after perithecial induction on carrot agar) Our study is the first report elucidating regulatory pathways controlled by FgVelB in Fusarium graminearum.
Project description:Using a 3′-tiling microarray covering the whole F. graminearum genome, we carried out genome-wide expression analyses of F. graminearum strains deleted for MAT1-1 or MAT1-2 locus, or overexpression the MAT1-2-1 gene during the sexual devleopment Our study is the first report which elucidated the putative target genes of the mating type genes in Fusarium graminearum during sexual development

A total of 4 chips were used for microarray. Total RNAs were extracted from perithecia and/or ground mycelia formed on carrot agar cultures of a self-fertile wild-type and a self-sterile FgVelB-deleted strain of F. graminearum with two biological replicates.
