Genes with putative light-sensing and signaling functions differentially expressed between dark:light and exponential:stationary conditions. (A) The expression patterns of light-sensing and signaling genes during diurnal growth. Genes are in rows and growth time points are in columns. Yellow and blue cells show higher and lower expression ratios during the experiment. Only genes with gene/condition associations by ANOVA at P < 0.01 or higher are shown (aqua boxes). See Fig. S9 for expression of all known photoreceptors. The multicolored bar indicates the following classes of genes: blue, putative photoreceptors and photolyases and green, PAS/PAC domain-containing genes. (B) Model for putative light-sensitive regulation of cell states by photoreceptors. Cellular states (interior labels) are hypothetically driven by the sensory and regulatory activities of differentially expressed photoreceptors (purple text).
