Analysis of the regulation of the Ustilago maydis proteome by dimorphism, pH or MAPK and GCN5 genes

► Ustilago maydis proteome map was most representative in the pH range of 5-8. ► Ustilago maydis can form filaments in vitro in response to acidic pH. ► Constitutive yeast and mycelia mutants (CL211 and GP25, respectively) ► Dimorphic related proteins and mutants related proteins were detected.
