Responses of PSII maximum photochemical yield (F_V/F_M) versus time in T. pseudonana (A–C) and C. radiatus (d and E) cultures treated with (closed symbols) or without (open symbols) the chloroplast protein synthesis inhibitor lincomycin. Bothspecies were grown at 30 μmol photons m⁻² s⁻¹ at 12°C (A), 18°C (B and D), or 24°C (C and E), then exposed to 450 μmol photons m⁻² s⁻¹ blue light for 90 min, and then allowed to recover at 30 μmol photons m⁻² s⁻¹ for 30 min. n = 4 to 5 independent culture experiments, ±se; most error bars within symbols.
