Figure 5

Isolated mutants in the schematic signal transduction of the photoprotective response in green algae. Light color (BL: blue light and UV: ultraviolet light)-dependent photoprotective signal transduction mediated by photosynthesis (depicted as chloroplast) and photoreceptors (PHOT: phototropin and UVR8) are shown. Two possible transcription factors (TF-X and TF-Y) are drawn as red boxes. The thickness of each arrow represents the extent of predicted signaling contributions. The predicted site (or area indicated by gray dashed boxes) of the mutants obtained in this study are indicated as yellow stars.
