Growth of the ΔsigD and control strains under mild oxidative stress. The A₇₃₀ of the cell culture was set to 0.1, 0.1 μm methyl viologen was added, and the cells were grown under continuous irradiance of 40 μmol photons m⁻² s⁻¹ at 32°C under air levels of CO₂. Each growth curve represents the mean of three independent experiments, and the error bars denote se.
