qRT-PCR assays in the engineered Synechocystis strains WT-INO1SS-ASPGI, WT-INO1SS-ASZWF, and WT-INO1SS-ASPFKA after providing the supplement of 2 mM theophylline. The error bar represents the standard deviation of three technical replicates for each sample. (A) Relative transcriptional level of pgi in WT-INO1SS and WT-INO1SS-ASPGI. (B) Relative transcriptional level of zwf in WT-INO1SS and WT-INO1SS-ASZWF. (C) Relative transcriptional level of pfkA in WT-INO1SS and WT-INO1SS-ASPFKA.
