Controlled expression of compatible and incompatible combinations of Ustilago maydis b-mating type locus genes bE and bW

ABSTRACT: 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 th
