Figure 1.
Survival of Chlamydomonas cells after irradiation by UV light as a function of the time in a light/dark cycle. Chlamydomonas cultures were plated onto agar medium and treated with equal amounts of UV light at different phases of a 12-h-light/12-h-dark cycle. Survival was measured as the colony-forming ability of cells following treatment as compared to that of cells that were not irradiated with UV light (modified from Nikaido and Johnson, 2000).

Figure 2.
Germination in different photoperiods in Chlamydomonas. A, Photoperiodic response curve. The germination efficiencies 10 d after mating are shown as a function of the light duration in light/dark cycles of 24 h total duration (white squares). Constant light (LL, filled square) represents cells continuously exposed to light for 24 h a day. B, Germination efficiencies in two different photoperiods (LD 12:12 versus LD 9:15) at different light fluences. Data are plotted as the total light fluence in a day, calculated as irradiance (light intensity, μE m−2 s−1) × (duration of light treatment in seconds). A and B, Germinated cells were counted at 10 d after mating, all data are shown with SEM (modified from Suzuki and Johnson, 2002).
