Figure 3. Getting the message: signaling pathways important for the day-night transition.

Figure 3.

The signaling pathways effective during the day-to-night transition consist of environmental sensing via RpaB and its cognate histidine protein kinase NblS, circadian status via RpaA, intracellular redox and energy status through changes in concentrations of NADPH and ATP and redox state of the plastoquinone (Pq) pools, chromosome compaction, and nucleotide signaling molecules such as ppGpp and cyclic-di-AMP (synthesized by RelA and CdaA, respectively).
