Fuz1, a MYND domain protein, is required for cell morphogenesis in Ustilago maydis.

Abstract: Ustilago maydis is a Basidiomycete fungus that exhibits a yeast-like nonpathogenic form and a dikaryotic filamentous pathogenic form. Generation of these two forms is controlled by two mating type loci, a and b. The fungus undergoes additional morphological transitions in the plant that result in formation of a third cell type, the teliospore.
