Fig. 2. Microscopic appearance of wild-type and swm1 mutant cells during growth at 38°C. Diploid wild-type (YPA24) or swm1 mutant (YPA207) cells were grown for 8 hours at the restrictive temperature on YEPD medium, washed and stained with Calcofluor. Photographs of differential interference contrast microscopy or Calcofluor-stained cells are shown. Arrowheads indicate the position of thickened septa.
