Figure 3.
Time course of CCM-related transcript expression in severely Ci-limited Synechococcus cells and induction of a high-affinity CCM. A through C, Relative abundance of a subset of CCM-related transcripts as determined by real-time PCR. Symbols represent the extent of induction or repression after the shift to low Ci at each time point as a percentage of the high-Ci amount (set at 100%) ± se for three separate measurements. D, Maximum photosynthetic rate (Vmax) and K0.5(Ci) for cells collected at each time point. Similar data were obtained from a replicate experiment (data not shown). Note the break in the y axis in part C. The scale is exponential after the break in C.
