Thylakoid protein extracts from plants grown in steady-state light environments ranging from 35 to 600 μmol m⁻² s⁻¹ (inset, representative of 4 experiments) (protein equivalent of 2 μg of chlorophyll/well). Each blot is representative of four separate experiments. Plants were grown under short days (8 h light, 20°C; 16 h dark, 15°C); growth light was provided by color 84 fluorescent tubes (Philips TLD 35 W, or Philips PL-l 55 W heat-filtered through 2 mm polyacetate). Photon fluence rates were measured at the leaf surface using a Skye Instruments (Llandrindod Wells, UK) SKP200 PAR detector.
