The MAP kinase Kpp2 regulates mating and pathogenic development in <i>Ustilago maydis</i>

Abstract excerpt

In the phytopathogenic fungus Ustilago maydis, fusion of compatible haploid cells is a prerequisite for infection. This process is genetically controlled by the biallelic a locus, encoding pheromone precursors and receptors. These are presumed to be coupled to a heterotrimeric G protein and a MAP kinase cascade, leading to activation of the HMG domain transcription factor Prf1. Here, we have demonstrated that...
