FIG 1.

Calcineurin suppressor (CnSp) mutations in the cnbRΔ mutant background restore hyphal growth. (A) Growth of calcineurin suppressor mutants (CnSp1 to CnSp4) and cnbRΔ mutant on a YPD agar plate at 30°C for 4 days postinoculation. While the cnbRΔ mutant shows smaller yeast colonies, the CnSp mutants show larger hyphal colonies. (B) The Mucor WT (R7B), cnbRΔ mutant, or CnSp mutants were grown overnight in liquid YPD medium with shaking at 30°C. Micrographs show that the CnSp mutants exhibit hyphal growth like that seen with the WT (scale bar = 10 μm).
