Fig. 4: Characterization of photosynthetic abilities in PCC6803 and Tol strains.
From: Mutations in hik26 and slr1916 lead to high-light stress tolerance in Synechocystis sp. PCC6803
a Absorption spectra normalized at the chlorophyll Qy band. b Fluorescence spectra normalized at the PSI band (<725 nm). c Fluorescence decay curves of PSII normalized to maximum intensities. d Fluorescence decay curves of PSI normalized to the maximum intensities. Graphs to the left and right represent PCC6803 and Tol strains, respectively. Blue, purple, and red lines represent 4000, 7000, and 9000 μmol m−2 s−1, respectively. The absorption spectra, fluorescence spectra, and fluorescence decay curves were measured at 48 h for all conditions.
