Extended Data Fig. 4: Low temperature (77 K) fluorescence spectra.
From: Enhancing photosynthesis at high light levels by adaptive laboratory evolution
a, 77 K fluorescence emission spectra upon excitation at 435 nm. b, 77 K fluorescence emission spectra upon excitation at 600 nm. With the exception of the data for LT at 700 μmol photons m-2 s-1 (for which n = 4), all spectra shown are averages of six biological replicates of Synechocystis cultures measured 7 days post inoculation. Data has been baseline corrected for emission at 600 nm (a) and 620 nm (b), and normalized to input culture OD730nm, respectively. Spectra were corrected for dark-signal (dark-offset ON) and the blank value (BG11 medium prior to inoculation) was subtracted.
