Yeast cells lacking Swi4p and/or Swi6p show pleiotropic changes in morphology and form true hyphae. (A) Cells of strain BH190 (swi6Δ::URA3/swi6Δ::HIS1 swi4Δ::hisG/MET3::SWI4-ARG4) (a, b), BH185 (swi4Δ::URA3/swi4Δ::HIS1) (d to g), and BH420 (SWI4/SWI4 SWI6/SWI6 URA3+ HIS1+ ARG4+) (c) were incubated for the indicated times in repressing medium at 30°C, fixed, and then stained with DAPI and calcofluor. Arrowheads indicate subapical, unconstricted septa, thin arrows show the first septa positioned away from the bud neck, and thick arrows demonstrate the first septa at the bud neck. (B) Strain BH420 was incubated for 3.0 h in the presence of 10% serum at 37°C for comparison of hyphal characteristics. Bars = 10 μm.
