    MAP Kinase and cAMP Signaling Pathways Modulate the pH-Induced Yeast-to-Mycelium Dimorphic Transition in the Corn Smut Fungus Ustilago maydis

    Acid pH induces the yeast-to-mycelium transition in haploid cells of Ustilago maydis. We tested two signal transduction pathways known to be involved in dimorphism for roles in acid-induced filamentation. In wild...

    Use of PCR to detect infection of differentially susceptible maize cultivars using Ustilago maydis strains of variable virulence

    Ustilago maydis was specifically detected in infected maize plants by means of the polymerase chain reaction (PCR) using oligonucleotides corresponding to a specific region downstream of the homeodomain of the b...

    Carboxin-Resistant Mutant of Ustilago maydis Is Impaired in Its Pathogenicity for Zea mays

    We analyzed the pathogenicity of chitin synthetase (chs) disruptants of Ustilago maydis obtained with the carboxin-resistant or the hygromycin-resistant cassettes. We found that only chitin synthetase (chs) muta...
