Fig. 3. Natural fluorescence emission.

A Time evolution of the fluorescence (x10⁻³ µmol photons m⁻² s⁻¹) emitted at two different spectral bands (λ > 645 nm, red line, and λ > 715 nm, black line) in a suspension of P. tricornutum (WT solid lines, DPH knockout dashed lines) illuminated with 430 nm light (30 µmol photons m⁻² s⁻¹) and B the corresponding power spectrum.
