Multiallelic recognition: nonself-dependent dimerization of the bE and bW homeodomain proteins in Ustilago maydis

Article Abstract:

The multiallelic b mating-type locus encodes two homeodomain proteins bE and bW, with allelic differences in the N-terminal domains of the polypeptides. The b mating-type locus regulates the sexual and pathogenic development in the pathogenic plant fungus Ustilago maydis. The different alleles of bW and bE dimerize using the variable N-terminal domains. Biochemical interaction with immobilized proteins shows the nonself-dimerization of bW and bE.

Genetic analysis of biosurfactant production in Ustilago maydis

Article Abstract:

The dimorphic basidiomycete Ustilago maydis produces large amounts of surface-active compounds under conditions of nitrogen starvation. The mutants described allow a genetic analysis of glycolipid production in fungi for the first time.

Functional expression of human dihydroorotate dehydrogenase (DHODH) in pyr4 mutants of ustilago maydis allows target validation of DHODH inhibitors in vivo

Article Abstract:

The pyr4 gene encoding microchondrial dihydroorotate dehydrogenase (DHODH) is cloned from the basidiomycetous plant pathogen Ustilago maydis. It shows that pyr4 contains a functional mitochondrial targeting signal.
