GlcNAc induction of hyphal growth in the hxk1Δ and h-d mutants. Cells were grown in synthetic medium containing 50 mm galactose plus the indicated concentration of GlcNAc for 2 h at 37 °C. The hxk1Δ and h-d strains were stimulated by GlcNAc at all concentrations tested to form elongated hyphae similar to the wild type. Strains used were the wild-type control (DIC185), hxk1Δ (AG736), and h-d (AG738) mutant. Bar, 10 μm.
