Fig. 2

Synechocystis cells expand exponentially under continuous illumination. a Representative time-lapse images showing growth and division of a pair of Synechocystis sister cells. Scale bar: 2 μm. b Scanning electron micrograph showing ellipsoidal Synechocystis cells, with some undergoing divisions, all of which are approximately symmetric. c Division planes in daughter cells are always perpendicular to the division plane of the mother cell. d Cell eccentricity (ratio of minor axis length to major axis length) as a function of normalized time during the cell cycle. Each gray line represents one cell, with the mean (black) and one standard deviation around the mean (orange shaded area) overlaid. e Single-cell growth (volume expansion) curves (gray lines) normalized to the generation time and plotted on a log scale with mean (black) and standard deviation (shaded orange area) overlaid
