NPQ development in WT and the <i>Dde</i> transformants of <i>Phaeodactylum tricornutum</i>.

<p>Cells were grown at low light (45 µmol photons⋅m⁻²⋅s⁻¹) before the experiment. (A) and (B) show the respective NPQs as a function of light intensity for a 5 min light exposure, while in (C) and (D) NPQ was measured as a function of time at an irradiance of 450 µmol photons⋅m⁻²⋅s⁻¹. Values are averages ± standard deviation (SD) of three to four measurements.
