MOESM4 of Electron balancing under different sink conditions reveals positive effects on photon efficiency and metabolic activity of Synechocystis sp. PCC 6803

Additional file 4: Figure S4. Chlorophyll-specific absorption spectra of PCC6803 under different sink–source availabilities. The spectra were normalized to the chlorophyll a concentration and the OD750 of the respective condition. The spectra were measured for cells in the investigated metabolic states low light high carbon (LLHC, panel A), high light high carbon (HLHC, panel B), and high light low carbon (HLLC, panel C).
