The cartoon summarizes how light dark-changes in the environment, the circadian clock, and feeding cycles influence translation. Arrows and text colored red are based on data from animals, while those in green stem from plants, and those in black apply in both kingdoms. Strikingly, a separation of translation into mRNAs that are preferentially translated at night or during the day is common in both kingdoms, and the functional annotations also partially overlap. Mt, mitochondrial protein; Ribi ribosome biogenesis proteins; Fe, iron. For details see text.
