Colony phenotypes of C. albicans strains. Wild-type and mutant strains were grown on YPS agar for 3 days (25°C) or 2 days (37°C), and colonies were photographed. Strains were grown in an atmosphere of 0.2% O₂ containing 6% CO₂ (- O₂ + CO₂) or lacking CO₂ (- O₂ - CO₂) or under 20% oxygen (normoxia) containing 6% CO₂ (+ O₂ + CO₂). In addition, cells were grown embedded in YPS agar under air. Strains used were CAF2-1 (wild-type [wt]), CCS3 (sch9), CCS4 (sch9[SCH9]), CCS5 (sch9[-]), CCS6 (rim15), IIHB6 (tpk1), and TPO7.4 (tpk2).
