FIG. 6.
Bioluminescence rhythms of per mutants. (A) Representative bioluminescence rhythms of the wild-type, per-1, and per-4 strains. The bioluminescence rhythms were monitored under LL at 17°C on HSM agar. (B) Period length of bioluminescence rhythm in per mutants. Data points and bars represent means ± standard deviations.
