Effect of the SQDG-defect on the cell morphology of Synechocystis or Synechococcus. Wild-type cells were normally cultured whereas SD1 cells precultured with supplementation of SQDG were transferred to SQDG-replete or -deprived conditions for 3 days. (A) Wild type cells of Synechocystis. (B) SD1 cells replete of SQDG. (C) SD1 cells defective in SQDG. (D) Wild type cells of Synechococcus. (E) SDL1 cells. Scale bars indicate 10 μm. Insets show two-fold magnified images. Shown are the results representative of three independent experiments. (F) Distribution of cell lengths in the wild type Synechococcus or SDL1.
