TranscriptomicsRNAseq of Ustilago maydis strain AB31 and AB31_delta_Num1
To elucidate the role of Num1 (Um01682) in Ustilago maydis, the transcriptome of wild type and Num1 deletion mutants was determined by RNAseq after b-heterodimer induction

TranscriptomicsUstilago maydis gene expression after growth on hydrophobic surface plus/minus hydroxy fatty acids
Infection-related development of phytopathogenic fungi is initiated by sensing and responding to plant surface cues. This response results in the formation of specialized infection structures, so-called appressoria. To unravel the program inducing appressoria in the biotrophic smut fungus Ustilago m...

ProteomicsMaize plant infection by Ustilago maydis is regulated by the fungal sulfur metabolism
The infection process is characterized by the simultaneous production of metabolites by both the pathogen and the host. Recently, it has been discovered that molecules generated during sulfur metabolism, mainly hydrogen sulfide (H₂S), play a key role in regulating which organism will prevail during ...

TranscriptomicsTranscription factor Rbf1 is the master regulator for b-mating type controlled pathogenic development in Ustilago maydis
This SuperSeries is composed of the following subset Series: GSE18750: Controlled expression of compatible and incompatible combinations of Ustilago maydis b-mating type locus genes bE and bW GSE18754: Effect of rbf1 deletion during controlled expression of of Ustilago maydis b-mating type locus gen...

TranscriptomicsAn Ustilago maydis gene involved in H2O2 detoxification is required for virulence
The fungus Ustilago maydis is a biotrophic pathogen of corn. In its genome we have identified an ortholog of YAP1 from Saccharomyces cerevisae which regulates the oxidative stress response in this organism. yap1 mutants of U. maydis displayed higher sensitivity to H2O2 than wild type cells and their...

TranscriptomicsGene expression in aerial hyphae in response to rep1 deletion in Ustilago maydis
The rep1 gene of the maize pathogen Ustilago maydis encodes a pre-pro-protein that is processed in the secretory pathway into 11 peptides. These so-called repellents form amphipathic amyloid fibrils at the surface of aerial hyphae. Strains in which the rep1 gene is inactivated (M-bM-^HM-^Frep1 strai...

ProteomicsQuantitative Analysis of Ustilago maydis Secretome in Wild-Type and Δrow1 Strains
In this project, we conducted a quantitative analysis of secreted proteins during the initial stages of the pathogenic program in Ustilago maydis. We utilized the AB33 strain, which contains the compatible bE2/bW1 genes controlled by the nitrate-inducible nar1 promoter. Consequently, in nitrogen-ric...

TranscriptomicsMaize tumors caused by Ustilago maydis require organ-specific genes in host and pathogen
Two-organism transcriptome profiling of infected seedling, adult leaf, and tassel demonstrated that both the host and pathogen exhibit organ-specific expression programs. Phenotypic screening of U. maydis mutants deleted for suites of secreted protein genes and maize growth mutants demonstrated org...

TranscriptomicsMaize gene expression during infection with Ustilago maydis strains SG200Dpit1 and SG200Dpit2
Ustilago maydis is a basidiomycete fungus that causes smut disease in maize. Most prominent symptoms of the disease are plant tumors, which can be induced by U. maydis on all aerial parts of the plant. We identified two linked genes, pit1 and pit2, which are specifically expressed during plant colon...
