Fig. 2. Diel oscillations of pigments and pigment-related transcripts.

a Molecular structure of investigated pigments and respiratory quinones associated with the photosystem. b Time-of-day average of fold change relative to 18:00 h (local time) of chloro- and carotenoid pigments, quinones, as well as transcripts associated with the metabolism of the pigment and quinone molecules. Error bars represent the standard deviation of averaged values for each time of day (n ≥ 6). Molecular structures and pigment and quinone data are colored according to compound group. If colors for transcripts match those of pigments or quinones, transcripts are related to the metabolism of the respective molecule.
