Synechocystis expansion and division statistics are most consistent with an adder model for cell-size regulation. Using distributions of birth sizes, division asymmetry, and growth rates extracted from experimental data (n = 278 cells for continuous and n = 96 for light-dark cycles), simulations of cell growth using the sizer (orange), timer (purple), and adder (yellow) models were performed. Slopes of relationships between growth statistics were extracted from simulations and compared with experimental data (gray circles) and their least square linear fit (black). a Schematic illustrating birth volume, volume increment during the cell cycle, division volume, generation time, and division asymmetry. bg Relationships between birth volume and division volume (b, e), volume increment (c, f), and generation time (d, g) are most consistent with the adder model. bd were determined for cells grown under continuous illumination, and (eg) are for cells under light-dark cycles. All volumes were normalized to the mean birth volume. Generation time was normalized to the mean generation time
