  • a Temperature sensitivity of progeny from mutant by AH12 cross.

  • b D, dominant; R, recessive; based on phenotype of swo/wild-type diploid.

  • c Based on ability of 1 m sucrose to restore wild-type growth on solid medium at semipermissive (37°) or restrictive temperature (42°) relative to growth at the same temperature without sucrose; see Figure 1.

  • d Based on ability of 0.1 mg/ml Calcofluor to inhibit growth relative to wild type at permissive temperature (30°). None of the swo mutants was resistant to Calcofluor at 0.25 mg/ml (data not shown); see Figure 1.

  • e Isolated independently in screens for hypercellular mutants (hypA; Kaminskyj and Hamer 1998) and polarity defective mutants (podA; S. D. Harris, personal communication).
