Figure 1. Regulation and conservation.

Scatter plot of all pairwise log₂ fold changes for the 859 gTUs orthologous between Synechocystis 6803 (x-axis) and 6714 (y-axis). The coordinates of each point resemble the pairwise log₂ fold change between a pair of conditions in one strain compared with the corresponding pair of conditions in the other. Some extreme examples are annotated. For iutA, encoding the TonB-dependent ferric siderophore receptor the regulation is conserved with maximum expression in -Fe and no expression in any of the other conditions. For gdbH, the maximum differences in fold changes between Synechocystis 6803 and 6714 appeared for 15°C/42°C, 15°C/stat. phase and 15°C/-C. For cmpR, the maximum difference in fold changes was detected for -C/HL. See Figure 2 and Table S1 for details about the expression patterns and the annotation of the mentioned genes; HP, hypothetical protein.
