In the phytopathogenic fungus  Sporisorium scitamineum , sexual mating between two compatible haploid cells and the subsequent formation of dikaryotic hyphae is essential for infection. This process was shown to be commonly regulated by a mitogen-activated protein kinase (MAPK) and a cAMP/PKA signaling pathway in the corn smut fungus  Ustilago maydis  but remains largely unknown in  S. scitamineum . In this study, we identified a conserved putative MAP kinase Kpp2 in  S. scitamineum  and named it as SsKpp2. The  sskpp2 Δ mutant displayed significant reduction in mating/filamentation, which could be partially restored by addition of cAMP or tryptophol, a quorum-sensing molecule identified in budding yeast. Transcriptional profiling showed that genes governing  S. scitamineum  mating or tryptophol biosynthesis were significantly differentially regulated in the  sskpp2 Δ mutant compared to the WT, under mating condition. Our results demonstrate that the MAP kinase SsKpp2 is required for  S. scitamineum  mating/filamentation likely through regulating the conserved pheromone signal transduction pathway and tryptophol production.
