Figure 1

Response to 20 °C–25 °C temperature gradient in the wild type Chlamydomonas cells grown at 25 °C. (A) Top view of cell suspension in trough taken 20 min after cell suspension was placed under the temperature gradient. (B) Cell density along the length of the trough, divided into five sections. Cell density was obtained by gray scale and normalized to the average value at time = 0 min. The density was obtained 0 to 20 min after incubation in the 20 °C–25 °C temperature gradient. Note that larger and smaller gray values (brighter and darker images) indicate less and more cells, respectively, and that the axis is inverted. (C) Time course of the changes in thermotactic index, using data shown in (B).
