Project description:Goals: Comparing the infection between Ustilago maydis SG200 with the wild-type strain FB1xFB2 previously published Methods: Comparative RNASeq analysis between U. maydis SG200 and U. maydis FB1xFB2 at three timepoints (axenic, 2dpi, 12dpi) Results: The RNASeq analysis in SG200 identifies differences in gene expression with FB1xFB2. These differences could be the result of a unequal contribution of each nuclei to transcription. Further analysis identified a set of differentially transcribed genes.

Project description:Ustilago maydis is a plant-pathogenic fungus that establishes a biotrophic relationship with its host Zea mays. The biotrophic interaction is initiated upon host penetration, and involves expansion of the host plasma membrane around hyphae, which is thought to facilitate the exchange of nutrients and virulence factors. Transcriptional regulators involved in the establishment of an infectious dikaryon and penetration into the host have been identified, however, regulators involved in the post-penetration stages remained to be elucidated. In the study we report the identification of an Ustilago maydis forkhead transcription factor, Fox1, which is exclusively expressed during biotrophic development. Deletion of fox1 results in reduced virulence and impaired tumour development in planta. Δfox1 hyphae induce plant defences including the overproduction and accumulation of H2O2 in and around infected cells. This oxidative burst acts as an intercellular signal, which elicits a specific host defence response phenotypically represented by the encasement of proliferating hyphae in extensions of the plant cell wall. Maize microarrays experiments were performed to identify genes involved in the observed plant defence responses on leaf tissue infected with U. maydis strain SG200∆fox1 4 dpi.

Project description:Investigation of whole genome gene expression level in Pseudozyma antarctica T-34, compared to Ustilago maydis UM521. To clarify the transcriptomic characteristics of Pseudozyma antarctica under the conditions of high MEL production, a DNA microarray of both the strains, Pseudozyma antarctica T-34 and Ustilago maydis UM521 was prepared and analyzed the transcriptomes. A DNA chip study using mRNA from the cultures of Pseudozyma antarctica T-34 and Ustilago maydis UM521 demonstrated the gene expression level of each strain.

Project description:The fungal pathogen Ustilago maydis establishes a biotrophic relationship with its host plant maize. Hallmarks of the disease are large plant tumors in which fungal proliferation occurs. Plants have developed various defense pathways to cope with pathogens. We used microarrays to detail the global programme of gene expression during the infection process of Ustilago maydis in its host plant to get insights into the defense programs and the metabolic reprogramming needed to supply the fungus with nutrients. Experiment Overall Design: In three independent experiments plants were infected with the solopathogenic U. maydis strain SG200. Samples from infected leaves were taken at 12 and 24 hours post infection, as well as 2, 4 and 8 days post infection. Samples from uninfected control plants were taken at the same time points.

Project description:The dimorphic fungus Ustilago maydis transits from unicellular sporidia to multicellular mycelium and accomplish its life cycle in planta with teliospore formation. Mutations in either of telomerase core subunits, trt1 or ter1 cause deficiencies or inability to produce galls and teliospores when crossed to a wild-type strain. Here, the global transcriptome analysis of two ter1Δ survivor strains of U. maydis is reported. It revealed the deregulation of many telomerase-deleted response (TDR) genes previously reported in other telomerase-negative fungi, as the DDR and stress response genes, cell cycle, subtelomeric and some telomere proximal genes. Interestingly, other differentially expressed genes (DEGs) found in those ter1Δ survivors were pathogenic lifestyle factors, plant-pathogen crosstalk, iron uptake, meiosis, and melanin synthesis. The studied survivors were phenotypically comparable, yet they exhibited DEGs between them. Our global results suggest the teliospore formation in U. maydis controlled by key genes of pathogenic lifestyle and meiosis
