Effect of the SQDG-defect on the light-intensity dependency of photosynthesis or LAHG in SD1. (A) SD1 cells precultured with supplementation of SQDG were transferred to SQDG-replete or -deprived conditions for 3 days. Then, photosynthetic activity was measured with illumination with different light intensities. The values are averages ± SD of three independent measurements. Closed circles, SD1-SQDG; closed triangles, SD1 + SQDG. (B) Wild-type and SD1 cells were precultured under photoautotrophic conditions with supplementation of SQDG. Wild type cells were further grown under the same conditions, while SD1 cells were grown under photoautotrophic conditions with or without SQDG-supplementation. Open circles, wild type; closed circles, SD1-SQDG; closed triangles, SD1 + SQDG. (C) Wild-type and SD1 cells were precultured under LAHG conditions with supplementation of SQDG. Wild type cells were further grown under the same conditions, while SD1 cells were grown under LAHG conditions with or without SQDG-supplementation. Open circles, wild type; closed circles, SD1-SQDG; closed triangles, SD1 + SQDG.
