a Photosynthetic efficiency of PSII (Fv/Fm) of 12 conditions at 84 h, same cultures used for proteomics. Data represent means ± SE (n = 3–4, individual data points shown, one experimental batch). Fv/Fm measurements are from the same samples used for proteomics. b Gross oxygen evolution (net oxygen evolution light minus oxygen uptake rate in the dark, normalized per biomass). c Net oxygen evolution in the light. d Oxygen consumption in the dark. All oxygen rate data (b–d) represent means + SE of combined replicates of two experimental batches, n = 6–8. e Total chlorophyll (a + b in femtomoles per cell) at 84 h. f Total chlorophyll (a + b in femtomoles per biomass) at 84 h. Chlorophyll data (e, f) represent means ± SE (n = 2–4, one experimental batch). Statistical comparisons are applied by Tukey’s HSD with adjusted p = 0.05 and represented by letters above bars. Source data are provided in the Source Data File.
