Project description:In the phytopathogenic Basidiomcete Ustilago maydis, sexual and pathogenic development are tightly connected and controlled via the b-mating type locus. The b-mating type locus encodes two homeodomain transcription factors, bE and bW, which form an active heterodimeric complex when they are derived from different b-alleles. Rbf1 encodes a zinc-finger transcription factor that is expressed upon formation of an active bE/bW heterodimer. To identify gene regulated by rbf1 independently from b, the b mating type locus was replaced by a copy of rbf1 under control of the arabinose-inducible crg1 promoter (strain CP27). Samples were taken 5h after induction of rbf1 gene expression. Strain JB2, carrying a deletion of the b-locus, was used as control.

The b-mating type locus encodes two homeodomain transcription factors, bE and bW, which form an active heterodimeric complex when they are derived from different b-alleles. Rbf1 encodes a zinc-finger transcription factor that is expressed upon formation of an active bE/bW heterodimer. To analyse the dependency of b and rbf1, changes in gene expression were monitored in strain AB31 (Brachmann et al., 2001, Mol Microbiol 42, 1047-1063) and in the derivative AB31Δrbf1 in which rbf1 was deleted. AB31 harbours the active combination bE1 and bW2 under the control of the arabinose-inducible crg1 promoter. Samples were taken 3h, 5h and 12h after induction of bE/bW gene expression. Strain AB32, which harbors the incompatible bE2 and bW2 combination, was used as control.

Strain AB32, which harbors the incompatible bE2 and bW2 combination, was used as control. Strains were grown to an OD600 of 0.4-0.6 at 28°C in liquid array medium: 6.25% (w/v) salt solution, 30 mM L-glutamine, 1% (w/v) glucose, pH 7.0 (filter-sterilized). For induction of the bE and bW genes, cells were inoculated in liquid array medium containing 1% (w/v) arabinose instead of glucose as a carbon source. For induction, cells were washed once with inducing medium; time point 0 h of the time course experiments corresponds to the first contact with inducing medium. Experiments were performed in two biological replicates for each time point.

Project description:Controlled expression of compatible and incompatible combinations of Ustilago maydis b-mating type locus genes bE and bW
| PRJNA123839 | ENA
Project description:In the phytopathogenic Basidiomcete Ustilago maydis, sexual and pathogenic development are tightly connected and controlled via the b-mating type locus. The b-mating type locus encodes two homeodomain transcription factors, bE and bW, which form an active heterodimeric complex when they are derived from different b-alleles. To identify genes regulated by the bE/bW transcription factor, changes in gene expression were monitored during a 12-h time course (0h, 1h, 2h, 3h, 5h, 12h) in strains AB31 and AB33 that harbor the active combination bE1 and bW2 under the control of the arabinose-inducible crg1 promoter and the nitrate-inducible nar1 promoter, respectively (Brachmann et al., 2001, Mol Microbiol 42, 1047-1063). Induction of bE1/bW2 in these strains results in a filament that resembles the infectious dikaryotic hypha formed after fusion of compatible sporidia. Strains AB32 and AB34, which harbor the incompatible bE2 and bW2 combination, were used as controls.
