Fig. 1: Growth comparison of the WT and ∆kaiA strains of Cyanothece 51142 in nitrogen-deficient media.

Self-sustained endogenous rhythms of ~24 h are reflected in growth under CL(a). Rhythm imposed by 12:12 LD cycles (b). The CL curve is an average of three independent runs of the WT and 5 independent runs of the mutant. The LD curve is an average of 3 independent runs of the WT and the mutant. Black bars represent dark phase of growth.
