Popis: When dark-grown resting cells of Euglena are exposed to light at the low intensity threshold of chloroplast development(7 ft-c) the antennas, including the LHCP II 26.5 kD apoprotein are very low or undetectable, but on exposure of these cells to more normal intensities of light for development (80–150 ft-c) the antennas, including the LHCP II apoprotein and chlorophyll b rapidly accumulate 1. Thin sections of similar cells at 3–7 ft-c do not show appreciable staining of either Golgi or thylakoids with rabbit immune serum against the 26.5 kD apoprotein plus protein A-gold, but when these cells are incubated at 80–150 ft-c specific staining with immunogold rapidly appears in both the Golgi and the thylakoids 2,3.
