Figure 5.

The effect of clinostating on the fluence rate-response curves (461 nm) for phototropism of the white mutants C171 and C213 (no octahedral crystals). Same experimental conditions as in Figure 3. ●, No clinostating. ○, With clinostating. For symbols without error bar, the se was smaller or equal to the size of the symbol. The solid lines connecting the experimental points represent the fits to the hyperbolic function: y = ax/(x + b) + cx/(x + d) (Eq. 1).
