Changes of the accumulation of low carbon signature metabolites in cells of the wild type (WT) and the PII mutant (ΔglnB) of Synechocystis sp. PCC 6803 after shifts from high CO₂ (5%, HC) to low CO₂ (0.038%, LC) conditions. Colored bars correspond to averaged values of three biological replicates measured by at least two technical replicates. Relative changes of metabolite pool sizes are represented by x-fold factors calculated relative to WT 24h HC. Error bars represent the standard errors (n.d. not detectable). Student’s T-test was applied to identify significant changes compared to WT 24 h HC.
