Switching frequencies of the white-gray-opaque tristable switching system in <i>C. albicans</i>.

<p>Gr, gray; Op, opaque; Wh, white. Colonies (strain BJ1097) were grown under the conditions indicated in the figure. Colonies were counted for switching frequency calculations. (A) Switching frequencies in air at 25°C for 5 days. (B) Switching frequencies in air at 37°C for 4 days. (C) Switching frequencies in 5% CO₂ at 25°C for 5 days.
