The main determinant of pathogenicity in Ustilago maydis is the b-mating locus, where establishment of heterozygosity is sufficient to cause galls/tumors on maize plants. However, matings between haploids where one partner contains a mutation, in e.g., the smu1 gene, encoding a Ste20-like PAK kinase, often show reduced mating and pathogenicity compared to(More)
Dimorphic transitions between yeast-like and filamentous forms occur in many fungi and are often associated with pathogenesis. One of the cues for such a dimorphic switch is the availability of nutrients. Under conditions of nitrogen limitation, fungal cells (such as those of Saccharomyces cerevisiae and Ustilago maydis) switch from budding to pseudohyphal(More)
