Phenotypic characterization of Synechocystis sp. PCC 6803 substrains reveals differences in sensitivity to abiotic stress - Fig 4

Cell size (A), dry weight (B), and glycogen content (C) of Synechocystis substrains GT-L (white bars), GT-B (red bars) and PCC-B (blue bars) under 25, 220 and 660 μmol(photons) m^-2 s^-1 of red light complemented with 25 μmol(photons) m^-2 s^-1 of blue light. The cells were cultivated at 32°C under input CO₂ concentration of 5 000 ppm in a quasi-continuous regime as described in the main text. Each value represents average from at least three independent experiments, error bars represent standard errors. Differences in cell size, dry weight and glycogen content among Synechocystis substrains are marked by letters above the particular columns (Tukey’s HSD post-hoc test following one-way ANOVA: p<0.05).
