Non-photochemical quenching (NPQ) of <i>aureo1a-15</i> (grey triangles) and <i>aureo1a-50</i> (white circles) <i>P. tricornutum</i> cultures depending on the incident light intensity in the measuring cuvette; corresponding WT data of Schellenberger Costa et al.

Mean values are shown with standard deviation (n = 9). The maximum NPQ of each culture condition was tested for the occurrence of significant differences between WT and aureochrome 1a silenced using a one-way ANOVA followed by a Holms-Sidak pair-wise comparison test with the WT as control group. Significant differences are marked with asterisks (<i>p</i><0.05).
