Project description:Fusarium graminearum and F. verticillioides are devastating cereal pathogens with very different life history and ecological characteristics. F. graminearum is homothallic, and sexual spores are an important component of its life cycle, responsible for disease initiation. F. verticilloides is heterothallic, and produces only modest numbers of fruiting bodies, which are not a significant source of inoculum. To identify corresponding differences in the transcriptional program underlying fruiting body development in the two species, comparative expression was performed, analyzing six developmental stages. To accompany the transcriptional analysis, detailed morphological characterization of F. verticillioides development was performed and compared to a previous morphological analysis of F. graminearum. Morphological development was similar between the two species, except for the observation of possible trichogynes in F. verticillioides ascogonia, which have not been previously reported for any Fusarium species. Expression of over 9000 orthologous genes were measured for the two species. Functional assignments of highly expressed orthologous genes at each time-point revealed the majority of highly expressed genes fell into the M-bM-^@M-^XM-bM-^@M-^Xunclassified proteinsM-bM-^@M-^YM-bM-^@M-^Y category, reflecting the lack of characterization of genes for sexual development in both species. Simultaneous examination of morphological development and stage-specific gene expression suggests that degeneration of the paraphyses during sexual development is an apoptotic process. Expression of mating type genes in the two species differed, possibly reflecting the divergent roles they play in sexual development. Overall, the differences in gene expression reflect the greater role of fruiting bodies in the life cycle and ecology of F. graminearum versus F. verticillioides. mRNA were sampled and compared from six time points across sexual reproduction in two Fusarium species

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: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

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 Δrfx1 strains. RNA-sequencing-based transcriptomic analysis revealed that RFX1 suppressed the expression of many genes, including genes for the repair of DNA damage.
